Pupik:
They did indeed do a digital transfer of Attack of the Clones. Unfortunately, they chopped out key sections of the film. One limitation of the IMAX film is that the reels are so large, that it limits the time to just under 2 hours.
So any film over that time, will be chopped.
Impressive film even withthe chops.
I'll note that for educational/informational films, it's tough to get kids to sit still for 2 hours. I watched the Lion King in IMAX, and a little over 1/2 way through, the kids in the audience were starting to fidget around.
