I have heard unconfirm reports that this re-issue of "2001" will be only with 6 track Mag sound as to preseve the original 6 track Todd-AO sound of the original.
I always belived that this will be in 70mm DTS, can anyone shed any light on this film?.

Last time I saw it in 70mm, I walked out. The shutter was out of time! I can't sit and watch a movie, now matter how good it is, when the projectionist either screws it up (which seems to be a normal occurrence), or when there is obviously an equipment problem. Shame on those guys who do not know how to time a shutter! Slight keystoning I can live with - but shutter timing? Bah - give me a break! 
The 35mm reissue prints may have black side boarders on the 35mm anamorphic release prints to preserve the original 2.2:1 aspect ratio.
70mm mag is the way to go in my opinion, it's the only way to take the ultimate trip.
'2001' set for re-release in 2001
LONDON, England -- Stanley Kubrick's "2001: A Space Odyssey" will blast back into movie theaters next year, beginning with a special screening at the 2001 Berlin Film Festival.
The remastered version will close the festival on February 18 and it will be re-released in several countries, including Japan, France and the United Kingdom, on March 7, the second anniversary of the director's death.
There will be one chance to see the movie before then, when the film runs January 1 at the National Film Theater in London. Warner Bros. made an exception for NFT since it spent a large amount of money to make a new print of the film.
There are no specific plans for a re-release in the United States, but Warner Bros. expects one later in 2001.
END
My source for info (not really more reliable than anyone else's) has it that there will only be a few ("less than 10") 70mm prints made. They will all be 70mm DTS, since mag striping is expensive and there is some doubt by Turner/Warner that the theaters still have mag eqipment and have the personal to operate it.
Don't bet the ranch on this info, but my source works in the accounting hierarchy (not in production) and sees some invoices. He also hates it there, and doesn't care if he get fired!
Does anyone else find some of these release dates for special things like this odd? It's almost like "hey, Kubrick is dead so let's all celebrate by re-releasing a classic of his". Just strikes me a bit strange. 
"He put forth his will, and the circling megatons flowered in a silent detonation that brought a brief, false dawn to half the sleeping world."
Depending on your mood of the moment, you can read this that Dave, as the star child, stopped all possible war and agression, or that he creamed at least part of the Earth into pot roast and gravy.
Of course, in "Childhood's End," the book that the book 2001 was loosely based on, Karallen watches the destruction of Earth from a safe vantage point outside the solar system.
Then, there is the short story that "Childhood's End" was based on...
Arthur C. Clark has a dark, misogynist, even human hating side.
FWIW, I've always admired Doug Trumbull more than Kubrick for 2001. Trumbull was the one that brought the space station to life, and for my money, the price of admission is repayed in the few seconds of it waltzing across the big screen. The bulk of the film is typical Kubrick excess and schmaltz.
Oddly, Trumbull's film, "Silent Running" has much more of a chance of being prophetic than "2001," and yet it is seen as a weak film. Then again, I invested in the original Showscan and the stock went in the toilet, so whadda I know?

As Gabrielle Union says to Kirsten Dunst "Bring It"
"For those who figured out our last calendar's none-too-subtle clue, and were looking forward to ringing in 2001 with 2201 - all we can say is that when it comes to Kubrick films, delay is a tradition. We llok forward to a grand 70mm restoration next fall."
By the way, The Castro is currently playing the original release version of Blade Runner, which apparently is not an easy thing to get Warner's to let you do, so I's sure The Castro, along with theatres in NYC and LA will be among the first to get the 70mm release...Castro did humongous business with the Vertigo 70mm restoration several years ago.
Every time it showed again in 70MM, I went back for another viewing. I never miss this opportunity! It's one of my favourite films and each scene is totally unforgettable.
Without a doubt, it's my favourite large format production of any era. (Jacques Tati's 70MM 'Playtime' comes in second.)
An anecdote I can't help but recall at this point: After my parents took me to see 2001, Star Wars was released and my parents were 'curious' to see what 'all the fuss was about'. They took me along and I couldn't stand it (I still can't). It held none of the fascinating beauty of Kubrick's film for me, even as a seven-year-old. This accounts for my taste in art and movies, or perhaps it's a reflection of it...
So each time I've seen 2001, I've seen it in 70MM. I did see a reel of it once in 35MM and that's just not the same thing. Therefore, this work of art MUST be shown in it's original production format, because that's a totally different experience! Therefore I'm compelled to agree with Brad, Mark and Scott on this one.
I'm open to the Mag/DTS issue. From what I heard while seeing Vertigo, DTS seems up to the task: to my ears it sounds very dynamic and sonically transparent.
As far as mag is concerned, it really does sound best, but... Mag is dead...Long live Mag! At $700 or $800 bucks for a mag head that will only last for 2-3 runs (I'm thinking that most of the places that even have 70mm are platter-type) and the cost of a mag-stripe print, I'm sure they will say "forget it." And if they are restoring from the orginal stems, who wants to pay for both a 6-track "Todd-AO" type mix down (that will hardly be used) and a 5.1 mix?
When you eliminate the theaters with 70mm that; a.) are unwilling to take the risk of damaging the print with poorly trained operators; b.) have screens that are considered "too small" to bother with 70mm (some management types actually believe this!); c.) do not have five speakers behind the screen (only three) - I think that (sadly) there is very little point in wasting the money for mag striping, especially if the difference can go to making more 70mm DTS prints.
In the early 1970's Walter Reede theaters built the Zigfeld in New York. About two years later, they went bankrupt, and couldn't get any current product. They must have booked "2001" 1-2 times a year from 1973 to 1977. I must have been there to see it 20 or 25 times. It was a 70mm print, in good shape, but I swear I watched it turn pink over the years.
The last time I saw it, just when the lights were dimming, a guy stood up on a seat in the front and yelled, "LIGHT UP!!"
When we re-released it in 1995, the print this time was brand new (we had it struck) but the print was less than great. Some (a lot) of vertical movement in most reels.
I loved how HAL came out of the surrounds...
the 35mm print was only dolby 'A' and consequently too boring too be of any interest.

Thus ends my Public Service Anouncement.
I agree on the easy set up of DTS over mag for the newer installations....think about it...if you have either a Simplex or Century, only the projector head need be changed if it is currently a 35mm only theatre.
With Panastereo's CSP-4600, mag installation would also be a snap for existing mag set ups with CP-500s or CP-65s or Panastereo.
In speaking with one of the studios that was looking into DTS and 70mm...they claimed that DTS wanted a pretty hefty premium to license the DTS format for 70mm in addition to 35mm (in addition to the negative cost for the 65mm time-code)...so much so that it would have been cheaper to strike mag prints for a small run.

"Old projectionists never die, they just changeover!"
...which is exactly what I'm trying to do. Wish me luck. 
BTW, the 35mm optical stereo print (a new one, I was told) I screened about a year ago or so did not have any black masking to achieve the 2.21 ratio. As far as I could see, it was a perfectly ordinary scope print.
I begged and pleaded to get the 70mm print instead (Sweden's remaining 70mm print still has its colours intact, and even though the sound has faded somewhat, the print is in very good shape) but to no avail. The stupid film company, Warner I think, that handled the Kubrick retrospective stated in writing that "Mr Kubrick would have wanted us to screen a new print..."
For years, he kept A Clockwork Orange unavailable on video in Australia and Great Britain due to the problems on its initial release in GB and the fact that Australia uses the same video format.
Now, the poor guy's still warm in his grave and guess what came out on video here about one month ago?
You guessed it...A Clockwork Orange.
Give it up Warners...no-one believes you.
Anyone have any updates on releases?

Yeah, I think you told me about that feature of the Panastereo unit in a previous thread. I really want one of those! But I really want those two extra speakers, too, so I'm not going to tell the management about that particular feature just yet. 
"2001" is magnificent, absolutely stunning, in 6-track mag; that "sensurround-like" sequence near the end always blows everyone away.
We cranked up the Stargate sequence (reel 7 or 8, I think) and layed down on the stage with our feet touching the bottom masking. Then, when the scene begins, put your arms out in front of you as if you were Superman. It's really like you are flying through time.
Proves you don't need drugs to have that induced freaky experience. 
...Daisy...Daisy...Give me your answer, do...
I mean, it's not the end of the world or anything, but if you want to run a film, run it properly, or just get a 35mm optical print.
On the other hand, the 5->3 (and, even, 5->1!) channel conversion option would be good to have around for emergency use, in case the film in question had panned dialogue and an amp or crossover or loudspeaker were blown. Obviously, the problem would need to get fixed, but it's better to have some options for temporary use (with apologies to customers and offers of refunds) rather than to be forced to cancel shows or lose some dialogue as a result.
I've always liked the way that some Dolby processors have a "bypass" mode which sends a mono signal to all three screen channels. I've never lost a center channel, but this would allow running the film in mono through the L and R screen channels if the center channel were to go south.
(Not that I advocate doing any of this, but I do like to have the ability to run the film with some type of sound rather than having to cancel a show entirely.)

At $700 for one mag head, 4 hours of labor to convert to 70mm operation, (that's if there's only one projector) the need for much better trained operators, the high cost if the print is damaged -and- the lean times theaters are going through now means that mag striping has (sadly) worn out it's welcome.
I think I'd rather have 70mm make a come-back with DTS (or SR-D or SDDS) then not have it come back at all.

But, I would politely disagree with with you, John. The best soundtracks I ever heard were with SR-70mm mag. Where I work, we have 4 THX, bi-amped theaters with digital(three SR-D, one DTS.) The digital sounds very good, but mag is (IMHO) better.
I admit, I don't know exactly what it is.. a certain clarity, warmth, richness... It's funny how we use words for other senses to describe sound. I understand that if you were to measure all the elements that make up sound (S/N, dynamic range, freq response, IM distortion, etc.) digital would probably have better techinal specifications.
But, (consistantly) my ears tell me 70mm mag sounds best. I know a soundtrack may not be reproduced *exactly* perfectly- 70mm may "color" the sound. I only know that it's right- because it sounds best.
4 hours to convert from 35mm to 70mm? What projectors are you using?
It takes a fraction of this time on a Vic 8 ,pause for torrent of US based Cinemeccanica abuse 
Leo
As far as I have heard the only two places that you can get mag striping done now a days are those two environmentally aware countries Mexico and China.

As always your news from across the pond adds to my knowledge.
New prints of A Place To Stand?
Ontari-ari-ari-o !! 
I haven't seen that for nearly 10 years.
It's an interesting film but why new prints? Do you still run this at Ontario Place?
Is there a spare print that we may be able to borrow sometime for a festival screening?
For Gordon, I agree that due to scan speed of the mag that the quality is there! And the
newer mag oxide coatings are indeed better
nowadays, but the vulnerability of the oxide to wear, abuse and magnetic fields leaves the probabilty of a lasting high quality run in the average multi plex very unlikely! How many people take and de-gauss there sprockets, film traps, etc on a regular basis, and how many even have a way to check for magnetism in these items?? I am sure besisdes a few old timers, techs and projectionists, and really serious theatre
owners, The average multi plex equipped with 70mm mag isn't even aware of the extra maintenance required! So I still stand on the
virtue of digital sound as the best all around way to reproduce with little or no degradation and minimal maintenance!
The average audience is not going to hear any difference between mag & digital anyway!! It's only nuts like me that like that stuff including vacuum tube amps!!! Oh well...

Perhaps I can make it to Lakeshore this summer ,well I can dream.Volcano is an interesting one as well especially when you hear the story about how it was made. Tripod legs melting in the Lava flow etc

This will be the first screening in the UK after the print returns from the Berlin Festival and before it starts a run in London.
Tickets are not on sale yet but keep an eye on http://www.bradfordfilmfestival.co.uk for details
- 2001 will not be released in Denmark. As i understand ONLY 70mm prints will be made, and with the high price attached to such a print ( and printing subtitels ), the film depot will not spend the money. I beleave it was first intended to make 1 print to share between Sweden, Norway and Denmark, and with-out subtitels. Why not?------------------

Would've worked, too. We always filled the auditorium (713 seats) when rerunning the old 70mm print of "2001". And for the life of me, I can't see why we can't screen that print. It's used, but it's in good condition.

Again, You haven't been listening carefully before bringing rumors into space: The Kubrick Family will not accept prints in circulation without subtitles for the actual location, -and that's why, Denmark, Norway and Sweden can't have a print to sheare, neither will they accept old prints.
Getting ready for 70mm ? - Well, -if those darn gremlins inside the rack hadn't been humming, as soon as projector 1 is on, it would take about 3 minutes per projector to get going. Anyone using more time, should convert for DP70 /AAII asap. Contact Your local dealer 
P.S.: Martin: Last time, You visited me, and wanted me to run 70m, I hadn't seen my bed for about 30 hours, -only been sleepwalking round the DP's. I was not in the mood for "I could have danced all night" or anything else. -Check that before leaving home next time... 
P.P.S.: Anybody got a gremlins-trap to spare...?
Per
2001 reissue in 70mm - a matter of human rights !
Well, I said it would drift out of sync after awhile, but then I remembered; Awhile ago, there was a guy who had a box that would sync audio to audio. I think his idea was to have a system like DTS, but instead of a sync track on the film, it would use the regular optical sound track to generate a pulse to control a CD player. Existing prints could be used with a CD player.
Does any remember this system?
Also, the four hour figure to change from 35mm to 70mm is based on the JJ's I used to use. I'm including de-maging the projector and hand tools; aligining and A chaining the mag head; checking the B chain (should be correct, but I'm not going to go through everything else and not check that); removing the optical lens assembly (would scratch the film); refocusing the lamp; tilting and kicking the pedestal to align the test film image to the screen (it's always a little off); unhooking the masking cable from the masking motor to set the masking to 2.21 (very few theaters will pay for a masking motor with 3 stops); changing to longer 1/2" spindles (easy on a V8!); fiddling with the trap holder (that dove-tail shaped part) to position the trap for good focus; removing the 35mm plastic pad rollers (yeah, you shouldn't turn it the wrong way, but..)
If you can do all that stuff in less than four hours.. come here!
At least for the large film party you will have next month everything should run smooth, right?
I have seen you dance in the booth with that reel of ''Dolly'' it was not a pretty sight i must say!
i'll rather see Miss Eliza dance at the Ball!

The picture and sound should be well aligned as Richard Huhndorf of Warners and Dion Hanson spent a considerable amount of time setting up the equipment for the Curzon's first 70mm screening for some time.
This is the same print we ran on March 10th and is coming back to Pictureville on May 18th for 10 days after it as finished it's run at the Curzon and been to a theatre in Cambridge.
PS "2001" is issued on DVD June 12, with the cleaned-up soundtrack and film material mastered from the 65mm negative.
PPS. The De-Luxe DVD set comes with a 70mm frame from the film. So, the only way to see "2001" in Denmark is on DVD while holding the 70mm frame. Ironic, huh!

35mm trailers for '2001' have been attached to all the UK prints of 'Best in Show' with an 'Exclusive 70mm presentation at the Curzon, Mayfair' tag at the end.
IMHO, if they're not going to rerelease the film in 35mm at all, then Warners should not be distributing 35mm trailers. They certainly should not be sending the trailers to cinemas which cannot show 70mm.
I've been told by our head office that they will try to book us the 35mm version when it comes out, so they obviously believe that there will be a 35mm release. If there isn't, then I've been wasting our customers' time for the last three weeks (apart from the tiny minority who are willing to travel a considerable distance to see it).
BTW, the cinema in Cambridge to which Dick refers is none other than my company's own Cambridge Arts Picture House - for screening dates and times, see
www.picturehouse-cinemas.co.uk/cb/whats.html
I know we are in different ridings of Yorkshire but Bradford isn't that far from York 
Good God you can even catch the mighty Iron Horse between our two cities as long as Railtrack / Northern Spirit (aka Spawn of The Devil) don't interfere 
Perhaps your management might allow us to send some flyers across for display at City Screen.
BTW there's a ticket for 2001 waiting for you if you wish to cross the border in May.
All I was trying to say was that mass-trailing a film which cannot be shown at the venue where the trailer is being shown could be off-putting to our customers. If the tag at the end had said 'showing ONLY in 70mm at the following cinemas...' then that might be one solution. As it is the trailer gives the impression that we'll be showing the film.
BTW, the 35mm trailer looks extremely sharp and the sound is great. It would be a pity if there is no 35mm release - I'd much rather be showing 2001 than Chocolat four times a day!
As to subsequent viewings, I have 3 copies in the film library, but Vault #160/10-4 is the most recent updating off-satellite from TCM, and this is an "Edited by Schmidt" version with a number of minutes snipped out of the apes sequence, which after you've seen once or twice becomes unbearably tedious. I plan to get the dvd which will obsolete all tape copies as they always do.
I'd personally rather see 2001 at home on dvd than watch a faded, reddish scratchy 70mm print. But that's just me, of cuss.
For new 70mm prints, my vote as a practical matter would be I think you are all better off with DTS stereo. For a mag print to be better than this -- and it IS possible, but not probable -- there are certain requirements.
1) Each reel of the new print has to have had the striping properly done and then recorded properly from the mag sound master... a process requiring careful, individualized attention by an expert. Given this, then
2) You must have a good system in place in the 70mm booth to play the print back on. My opinion is that ONLY a Dolby mag preamp or a CUSTOM-BUILT mag preamp system such as I have done will give good results. [If you are so unfortunate as to have Century 70/35 transistor garbage in your booth you are in BIG trouble.]
3) And there is the issue of the expensive mag head in the penthouse wearing out fast -- lasting only 2 or 3 shows? geez. that's not much.
In the beginning back in 1976, Dolby actually didn't really want to produce a mag preamp unit, but was forced to design and manufacture small runs of the MPU- units because the theater mag systems were so awful. There were only two good ones: the original 70/35 system produced by Ampex [of which I believe few survive today] and the Simplex XL system... and both of these to some extent suffer from possible tube noise in their preamp stages. But either of these, if tweaked up properly had the POTENTIAL for pretty-good, if not excellent mag sound. Unfortunately in the typical theatre the systems were NOT properly maintained as the exhibitors wouldn't spend the money.
Thus, this led to the Dolby preamp as the only practicable remedy in the field.
It is also a fact that IF and GIVEN a custom-built mag preamp system, 4-track mag can outperform Dolby stereo on the bi-lateral optical tracks, even with the A-chain NR system. And definitely in 70mm, that's a given. But I believe that very few of you working in the field today will actually have had this sort of hands-on experience. And to the best of my knowledge 4-track mag prints haven't been done for many years.
Yet, a superlative custom mag preamp system CAN BE BUILT and the cost of components isn't all that bad. But it's a lot of labor to carefuly hand-wire it all together.
During the approx. 1960-1976 period, before the Dolby system with Star Wars came out [and Fox FORCED theatres to have it installed to get Star Wars after it became such a big hit] many features WERE produced with a stereo mix on the mag sound master even though most release prints were in mono optical. A handful of prints were striped and recorded in 4-track mag and these were seen in the major markets only; such as in LA and Radio City Music Hall in NYC where I guess for sure the system was maintained, altho I've never been there. [I'm afraid to go to New York!]
It is due to this that we have today so many of these great films in stereo on the AMC, TCM and FMC satellite channels; and such wonderful things as the DVD release of "The Time Machine."
J.
2001 is now showing at the Curzon Mayfair in London, UK. The print is 70mm 6 track mag with SR noise reduction. There is no censor on the beginning of the feature so as to allow the overture to be played with the house tabs closed.
All the best
Steff
I think you are being a bit over the top there. Which version of the Dolby mag pre-amp are you using as the standard? The 92?, 92-2, 92-3, 92-4 or the latest, 92C?
Also the Simplex 6-4-1 mag system was a bit hissy if memory serves...Germainium transistors, as I recall.
Teccon also manufactured mag pre-amps? Ever tried one? They made them for use with their mag heads. The 80000 series were stand alone. They also made special card that fit the Dolby MPU card cage. It had two level and EQ settigns so one could have one set up for pre-1983 and one post-1983 standards or one for 24fps and the other for 60fps.
Recently Panastereo has come out with new mag preamps (Two different units, actually). Ray Derrick is a bit of an analog nut. Are you ready to rule out his preamps or have you used them and determined they are not up to Dolby standards?
To sum things up...sure Dolby pre-amps are good and a worthy standard by which others should be judged (the 92C sets up wonderfully for either 35 or 70mm) but they certainly are not the only ones to consider.
Oh and on 35mm magnetic....there is no doubt that it CAN sound superior to optical, it often suffered from inferior preamp as you have noted, inferior mag heads and the god awful 12KHz tone on the surrounds. If it were produced a decade ago with Teccon mag heads available, Dolby preamps (or others even) and Dolby SR noise reduction...sure it would stomp all over optical but that isn't how it was originally presented. I have run 4-track on faily high-end systems (using both Dolby and Teccon pre-amps) and it wasn't a perfect system but certainly better than optical for its day. An old 4-track vs a current optical with SR...the Optical SR would be judged to be superior, in my opinion, by the vast majortiy in all respects except descrete channels.

"Old projectionists never die, they just changeover!"
I've been retired for many years [for more on me, see [WHO?] post in film-yak] so what I am speaking of here is somewhat ancient history, and no, I do not have first-hand experience with the preamps you mentioned but no doubt they are excellent. Possibly I could build up something equally good, but there is no need, and I am emphatically retired! If you have a GOOD wheel, no need to re-invent.
The Simplex 6-4-1 system we [I] are speaking of is 100% tubes, circa 1955+ approx. as was the Ampex. These were the ONLY good mag systems, all the rest were absolute GARBAGE, and horribly overpriced garbage at that. Of course the Altec speaker systems had great potential, but it was like a racehorse trying to pull a donkey cart with a flat wheel.
Theatre equipment mfrs. wanted cheap stuff they could sell at high prices and just never seemed to get in touch with the right people who could have designed and given them something better. Never would you find any of the theatre junk at the studios, where practically everything was custom-built. That's why 2001 and many other great films could sound so good!
It may well be that only today is the full potential being realized, based on what I hear at home off-satellite, and especially dvd.
There was no good transistor sound anywhere until McIntosh Labs came out with their solid-state equipment; then gradually other equipment improved but it took Years.
[McI is what I use exclusively at home; it's been running 14 hours a day for 25+ years now + Voice of the Theatre.] Dolby Labs was FIRST to produce good solid-state systems for theatres, and they only did the front end.
Power amps had to come from elsewhere. Of course today good amp power is plentiful and cheap. McIntosh eventually discontinued the amplifier clinics when the competitive gear finally caught up and nearly everything was "a straight wire with gain."
One of my little specialties years ago was producing optical sound reproduction which was so good people thought they were listening to mag. Custom-built. That was the only way. Some optical tracks wre amazingly good. One of my favorite test reels is #1 of "Where Eagles Dare," mainly the overture.
Another old trick: if you had L-C-R speakers on stage, feed mono signal thru all 3.
j.
What exactly do you mean by custom-built optical sound reproduction? Pre-amps? Or more than that?
Interesting, I had been toying with the idea of putting mono through L,C,R myself. Anybody know offhand how to do this in a CP200, or if it's even possible with Dolby processors?
Anything is possible with the CP-200. As to L,C, R on mono...I have never liked it! I find that it makes dialogue muddy. There was a period in the '80s and early '90s where on 70mm some films would have "draped dialogue" such that it was on all three channels with L and R at reduced levels. Again, this made the dialogue worse in most cases since if you are near the left side of he screen...it pulled the dialogue to the left even if the actor was on the right.

"Old projectionists never die, they just changeover!"
I suppose if the screen was really wide, it might make things better for people on the extreme left and right. The screen I tried it with was about 50 feet wide.
Chris: You will have to change a few things on the CP200 to "mono" the channels. Do you know about the DIP switches on the format cards, and how they work?
When the switch is thrown to "Proj 1 and remote" several relays are switched which feed the Dolby optical preamp directly to the CP200 output and connects the power amp inputs together. Everything gets sort of connected to everything, including the non-sync 1 signal, and the mag preamp outputs. The relays also removes power from some PC boards, but not all- the optical preamp, the non-sync and (if running mag) the mag input PC boards still need to be working. A simple 2-relay circurt with a resistor and cap will allow c/o's.
I don't think proj 3 or 4 (if the theater had them) would work. If I remember, a LED would blink, reminding you the unit was in emergency mode (as if you would forget!) Again, a resistor and cap setup would provide the blink. Problem was, you could hear a "tick" in the sound as it charged and discharged during quiet scenes.
No, I don't know about the DIPs. Do the installation/operation manuals describe their use? I recall flipping through one or the other or both and coming away with little information on how to modify it. (If my tech is reading this right now, don't worry, I'm not going to do anything on my own
)
Chris, I would be glad to come out to Hawaii and fix any problems you may have....! 
So there is clearly going to be a 35mm release of some sort (we cannot show 70), though more than that I could not say.
quote:
Warner Brothers is still working out their theatrical plans, from what I understand, but the 70mm restrictions (ie, most theaters don't have 70mm) mean this won't be getting a wide release, so it will never match the sheer box office of "The Exorcist" rerelease.

It would be nice to see this in 70mm everywhere, but that's not going to happen. If I have to choose between being able to see at my local theater or not, I'll go with being able to see it in 35mm.
The closest place to my town possibly capable for showing "2001" in 70mm DTS would be the Hollywood Theatres Penn Square Mall 10 in Oklahoma City. They have 70mm capability in the one THX auditorium; however, their DTS unit is one of the original white and blue 2-drive units. My understanding was DTS 70mm required a DTS-6D player or DTS-6AD Cinema Processor for compatibility with the 70mm reader. If that is the case, then a number of 70mm theaters that installed DTS early on could be possibly cut out of the loop. Even outside of that, I don't think very many traditional 70mm houses have the 70mm DTS readers either. Don't they cost around $1,300 (as compared to the $700 or $800 for the 35mm reader)?
Mag stripe audio with Dolby SR can sound incredible. I was fortunate enough to see a few 70mm SR shows when I lived in New York. For instance, I was really blown away by the sound quality of "Born on the Fourth of July" with its 70mm SR showing at the Ziegfeld at the end of 1989. The DVD on the otherhand just sounds kind of flat. Dolby SR mag has dynamic range of 22 decibels above reference, which is better than the 20db of gain you get with 16-bit digital.
I really hope "2001" is supported by a decent number of 70mm prints. I don't think 10 prints or 15 prints is enough for this landmark film. I just hope some 70mm prints are booked in some quality theaters in Texas or Oklahoma so I don't miss it.
When "2001" is released, I certainly want to see the 70mm end of it promoted well in the ad work.
All you need for DTS 70mm is a 70mm reader and *ANY* DTS unit (Even the DTS-6). It is *highly* recommended that two readers and drive units be used for failsafe redundancy, but given the extreme robustness of the DTS70 track I would think its not THAT necessary... Has anyone who has projected DTS70 had a timecode dropout or other failure requiring the second reader/unit to come in?
Aaron
On testing the next morning it all ran fine. Ain't that the way? For 300 plus patrons...problems...for little ol' me...perfect.
And it sounded and looked fantastic.
Our surrounds (in those days) were so good that in the cemetary scene where the birds tweet in the surround channel, I actually believed we had a bird in the ceiling of the theatre.
From what I hear, that theatre now sounds like shit.

Children really brighten up your life...they never turn off lights.
I've seen DTS 70mm in action only on showings of "Vertigo" and "Titanic" at Dallas' Northpark #1 theater. That grand place is demolished and I know of no other theater in the Dallas area equipped for 70mm DTS (outside of maybe any of the three IMAX theaters in that area; the 70mm DTS capable Showscan theater at UA Galaxy was reportedly dismantled).
With 11,000 watts of sound and a 19 metre screen this will be a presentation not to miss.
I believe this same equipment was re-installed at the Filmhouse Richmond and could still be in use today.
though: out of focus and a frameline showing for the first few minutes, the Academy plate seriously undercut, houselights left on the low setting throughout the feature and an almighty 'crack' on the soundtrack every time a reel change join went through.
This is not a new print. It's about 5 years old and has registration problems. See earlier in this thread for more info.

Resolved: Warner Bros.' planned theatrical re-release of 2001: A Space Odyssey will not be happening, despite a newly struck, digital-sound 70mm version having been shown at February's Berlin Film Festival and then at Roger Ebert's Overlooked Film Festival. And despite WB's funding of both a 35mm remastering with a new digital soundtrack (which almost opened at L.A.'s Nuart and S.F's Castro theaters last January, only to be pulled) and the new 70 mm version. A shame. I wanted once more to see this masterwork in 70mm on a big screen with needle-sharp focus. If you haven't seen it this way, you haven't seen it.
Thats too bad, I was looking forward to it, having never seen it. I know, slap my hand. 
JK
The "Berlin " print has a SR mag track not digital. It's playing in Pictureville Cinema here at the museum until May 28th.
BTW Unfortunately on it's travels since originally playing here in March the first 3 reels have picked up some rub marks down the extreme left hand side.
But it still looks amazing.

It's about time.
"A digitally restored print of '2001: A Space Odyssey'
will be released in theaters for a limited 70mm run,
Warner Bros. said Wednesday.
"Seattle's Cinerama will start screenings of the digitally
restored classic Oct. 5, with Dec. dates set for L.A.'s
Egyptian Theatre, San Francisco's Castro and the Uptown in
Washington D.C."
Funny, no mention of sound format: mag, dts, nothing.

Dick: any idea the cinema that did it?, as only a hand full screened it in the UK
>>NO 2001 IN 2001
Although it had seemed like a foregone conclusion that Stanley Kubrick's 2001: A Space Odyssey would be restored and re-released by Warner Bros. in 2001, it may only get limited distribution in four cities -- Seattle, Washington DC, San Francisco and Los Angeles -- late this year, according to Wired magazine. A wider release is planned for 2002 if this year's screenings produce a profit, the magazine said. Warner's hesitant plans have received a tongue lashing from critic Roger Ebert, who featured the film at his Overlooked Film Festival in April (although the film could hardly be described as "overlooked"). Ebert told Wired: "Seeing it on a big screen in 70mm is not just seeing a better picture, but essentially having a different experience. ... Those unlucky enough to have seen it only on video have not really seen it at all."<<
Well put, Roger.
By the way, did you notice the rub marks Ben mentioned above?

There were new print(s)made for the US.
So it's still playing in the UK? Does the UK still have a lot of 70mm installations?
Scott's list at http://www.redballoon.net/current70mmforeign.html
give's a list of most of the theatres that have screened 70mm in the last few years however having looked at the list this morning I notice some omissions. Thomas Hauerslev also has an extensive list but I tried accessing this just now and it wouldn't connect.
Scott
Will try and gather more info for you on Showcase installations(Nottingham + Leeds + ?) .,Cambridge Arts Picture House etc. who have recently run 2001.
the chance to show 2001 in 70mm has brought to life a lot of dormant 70mm theatres which just goes to show what can happen if you get the right title.
Not sure what could be done to "polish" or rejuvenate the back side of a mag-striped print. Acetate prints used to be "glass wheel polished" to "heal" base side scratches, but the solvents would attack any striping. ESTAR base prints can be treated with UV-cured overcoats like 3M ScotchGard Film Protector (aka "PhotoGard") or Dacar ImageGard, but could not be coated over the stripes. AFAIK, cleaning and/or rewashing could be done by any lab that routinely handles 70mm prints.

I am sure that the only lab in the UK that can work with 70mm elements is Technicolor London. They do not use 70mm very often but the equipment is in place.
------------------
As far as photoguarding is concerned it can be done over selected areas. We used to have problems with photoguard around the perf areas on IMAX films shedding on the input stator so they then modified the process to just coat the image area.
