FYI, the Castro Theatre in San Francisco is in the middle of a two week engagement of Alfred Hitchcock's "Dial M For Murder" presented in its original Naturalvision 2-strip 3-D. According to the Castro's calendar, Warner Brothers has struck new double system copy for this engagement.

Now the bad news...I just called the theatre's recording to find out the showtimes and learned that due to tech difficulties today's showings (Sunday, 11/28) are not in 3-D, but they may have the system back up and running on Monday for the remainder of the week. It would be sad if they ended up having to play the last few days in 2-D as the theatre invested in a new silver screen and synchronization motor for the two projectors.

I can see running into setup problems with the synchronous motors, but unless I'm missing something, they'd have to have a traditional 2D print in addition to the 3D print.

There's no way to run a 3D print and watch it like 2D - that I'm aware of.

hmmm, vewy intewesting...

Dial M is two-strip 3D. When I ran it last January, we got one of the prints that was struck for the "75 Years of Warner Bros." festival. It was the "right-eye" version that was printed off of an intermediate element that was dated 1981 (which would make sense, given that the last 2-strip reissue was done in 1981). I guess that this is the long-winded way of saying that 2-strip 3D features can be converted to single-strip 2D features by just running one "half" of the print and using normal lenses (Dial M is 1.33, but probably looks OK at 1.66 as well).

Oh, one more thing--I guess that 2-strip prints are shipped on 6000' reels. The right-eye version that I ran was shipped on (and projected with) standard 2000' reels...

Oh.

We ran a single-strip anamorphic version of Dial-M two years ago.

I would still think only half of it would be blurry... guess not.

On a recent trip to Las Vegas I had the oppertunity to catch a few of the IMAX show that they have in town. By far the most memorable of them is the IMAX 3D motion simulator ride that they had at Ceaser's Palace titled Race for Atlantis. I was very impressed with the quality of it images.

There is no reason that either the left or the right eye cannot be shown independantly as seperate 2 presentations
In many cases the orignial 2 strip prints were shipped out as 2d prints wiht just one eye shipped
There is no blurry image as they are conventional 1.37:1 images
Even the single strip can be shown 2 d by projecting in scope and moving the bases to align only one of the images on the screen
For House of Wax a few years ago all we could get were single strip side by side prints so to get enough light we synced to of them togather with conventional scope attachments and interlocked the 2 machines with opposing apperture plates

Hello
I did a lot of 3D screenings in europe for different festivals. I work for an archive where we collect 3D films for many years. We do sideby side and "over and under" single strip projections. I made a special alingment film so you don't have to test with the copies. I works really great. For the over and under film we rebuilded the Isco 3D lenses so it also works. If anyone sells copies or lenses we always look for that.

of course we rebuilded the Isco lens for the side by side anamorphic versions. (not for the "over and under" i wrote something wrong).
The single strip copy of dial M for murder we have is really neat. there is nothing like focus problems or anything else. One hint: it is the only 3D film which has a making between the frames where you can adjust the lenses properly. If someone has this print as single strip have alook.
All other films totaly differ with their measurements. In fact there are some wich can not be adjusted with the isco lenses at all.So you have to rebuild them (shorten the pin wich keeps the two lenses apart).

Why rebuild the Isco lens when the Paramount mirror box has far better range of adjustment for different spacings.
There large size allows even for a certain degree of keystone correction in the overlap of the two images
I have even used them on side by side flipped on there side with small intigrated anamorphics
THe split lens are not the best route to go.

I agree with Gordon, mirror boxes have more flexibility. Also, polarizing filters or lenses lose polarization with repeated exposure to the high intensity light from a projector, resulting in ghosting. Change out on a mirror box is more practical.

"Dial M" and "H.O.W." were the best 3-D of the 1950s films, IMHO. I need to get frame sequential VHS copies for home.

As a little kid, I had the awesome experience of seeing The House of Wax as a special one-time show at a first run theater which was held in conjuction with a lecture that Mr. Price gave at the University of AZ. What a most gracious and polite gentleman he was!

Anyhow, I occasionally see 3-D prints for sale in Big Reel. Of course there are no exhibition rights.

25 years ago, I saw several 3D films at a "3D film festival" in New York. Three Stooges, Dial M, House of Wax, many others.

They did it the "real" way, with two projectors. I peeked in the booth; (which was tiny) they had a drive shaft with universal joints on one end going from one projector to another. I was talking to the operator before the show started; he jokingly shouted at the projectors; "I defy you to get out of sync...!"

I had a negative opinion of 3D films, until I saw some of the better quality ones (like Dial M.) without any; "3D for the sake of 3D" scenes. I mean, I would'nt want to see it everyday, but for some films that want to immerse the audience, (Jurassac Park?) I think it could still "sell." But, it has to be done right from camera to projector, (no selling those seats on the far sides!) or people will get annoyed.

Well, 3-D was one of the gimmicks they came up with to get people back into theaters when they were staying home watching TV. With business going down, maybe they could try 3-D again- though hopefully done on competent movies, not stuff like "Spacehunter". I've always been a 3-D fan and wondered why 3-D's always been a 'fad' and not something that's been used seriously.

Sad to say, I think theater owners killed 3D by getting cheap with equiping theaters (underlit lamps, selling seats too far left/right, etc.) Studios responded to this cheapness by using non-Polaroid systems, many which looked even worse when projected poorly.

I think that by 1962 or so, the public just said "Screw this."
