Just got home ... our IMAX GT projector has just been equipped with the hood-mounted, automatic polarizer swing mechanism. It's a pretty nifty doohickey, even if it's going to be yanked off when Superman's run is through.
While it's mounted (as it would be a pain to remove, what with the hoses), the polarizer glass plates themselves can be removed by unscrewing the sides and sliding them out, so you can run normal 2D movies. While the plates are in, the upper (right eye) deck is stationary, as normal. The lower (left eye) polarizer swings up with a pivot on the right side, between the plates. So, when it's open, allowing the left eye 2D to play clear, the polarizer is in front of the upper lens and polarizer at a 90 degree angle. (At that point, I think both filters are aligned with each other, but it's playing black slug anyway, so it hardly matters.)
Programming in the DTAC event list for opening and closing the mechanism is a snap ... especially if the DVD-ROM soundtrack is going to include the cue marks in the file, like they already do for "Begin END Credits", where you can drop in a "house-lights-to-half" cue or similar.
We also got a battery back-up for the QT Reel Unit. In the event of, say, a system E-shut, the platters won't have their power cut off as well. That caused damage to prints in the past, when the tension arm would quit communicating and the momentum of the print alone would pull itself way too tight and possibly out of the output sprockets, when the projector came to a complete stop within that second-and-a-half. And now that shouldn't be a concern!
FURTHER UPDATE!
What a gyp! The four sequences are, respectively, 2:59, 6:42, 6:29, and 1:16 ... for a total of 17 minutes and 26 seconds of 3D, in a film with a total running time of 2 hours 31 minutes 6 seconds.
The assembly should be completed tonight, at which time I will run it. Review to come. [ 06-25-2006, 05:48 PM: Message edited by: Brian Michael Weidemann ]

quote: Mark Lensenmayer A couple of the "take glasses off" cues are a bit hard to see.
There's a reasonable explanation for this: either one eye goes black, which is the only eye that flashes the red "take glasses off" symbol, while the other eye sees the movie properly, before the polarizer swings away ... OR ... (if the polarizer timing was adjusted), it swings away immediately before the right-eye goes black, which allows both eyes to see an image which is mostly the left-eye print's main movie images, with the right-eye's flashing symbols difficult to make out because they're superimposed (dimly) on the screen, PLUS the fact that the polarizer that swung out of the way is now obscuring the right eye deck THAT MUCH MORE, because it is held in front of that lens. There was a lot of thought to this upgrade, and it makes some sense (because it allows the left-eye print to play alone as a 2D), but it's hardly perfect from a presentation standpoint.
I've been sitting on these for a few days, but here are some images from the Superman Returns IMAX debacle ...
The print came in a total of 88 reels, 44 per eye. The right eye was mostly black slug, in the red-labeled boxes.

When the print assembly was completed, there was a pile of plastic bags which had held all the reels, and the unfolded boxes which is, I'm sure, a good deal of recyclable cardboard.

The 3D sequences are indicated by three symbols displayed along the bottom of the right eye print frame.

The four 150-minute 72" platters of the QTRU, at full speed during the beginning of the presentation; two feed, two take-up. (A 120-minute platter is leaning against the wall on the right.)

I've got a video of these things ramping up, but I'll have edit it first and adjust contrast/brightess settings to make it presentable before I link to it, or send it to Brad for posting, or something. These things sure do haul ass!

Yep, each print is fitted with eight of the screw-in clamps. That's not a single band, that's just the speed they're spinning ... well, the extended exposure necessary from the camera in order to get a decent light reading, that sure helped the illusion.
And our booth really is not too cramped, despite the angle of the picture.
Yes, the large crowds are what make it all worth it! The IMAX is the only auditorium selling out (546 seats) for this movie, and each day so far has seen the last available day's tickets all sold by noon or 1:00pm. They all cheer and laugh and leave happy! (Well, at least they all did when we finally got our auditorium's AC up to 100%) The funny part is people excited over a movie like this usually cheer after the trailers, when the feature begins. We get people booing at that point! Surely, however, it's due to the first "remove your glasses" prompt.
