morgan freeman's character was a bit like Q of James Bond

confirmed by others it was changed!Affirmative!

Saw it Yesterday on I-Max screen. AR does change lot of times.

Picture filled full screen width all the time. Difference was in vertical height. Film started with 3:1 or wider AR (Bottom of pic was above Exit sign) that's smallest picture. Picture height jumped a lot. At times bottom of pic was above exit sign, middle of door, floor level (top of pic too changed symmetrically). When full screen filled, side to side, floor to ceiling, AR was aprox 16:9. Often it was 2.35:1. There were other variations as well. But not sure if it was supposed to be multi AR as I did notice vertically squished picture often. Picture was not squished in 16:9 AR (i.e full I-Max screen) but sure it was squished in some of the wider ARs but not all the time. Looks like, no one (film printing, cinematographers, projectionists etc) can notice vertically squished picture ??

The Dark Knight is back for a return engagement in theatres and Imax in the US on 23 January, 2009!

being re-released in imax-big cinemas in india as well

IMAX DMR®

The IMAX Experience® is known as the world's most immersive movie experience. Now through the magic of IMAX DMR® (Digital Re-Mastering), movie-goers can experience a whole new way of seeing Hollywood blockbuster movies.

IMAX® Corporation has developed a total system to re-master 35mm live-action films into 15/70 film format for exhibition in IMAX theatres. Referred to as IMAX DMR®, this technology digitally enhances the image quality of 35mm motion pictures for projection onto screens up to eight stories high. The images are just as big, clear and beautiful as those films originally produced in the 15/70mm format.

How does this happen?

* IMAX DMR® starts by scanning, at the highest resolution possible, each individual frame of the 35mm film, converting them into digital images.
* Next, image enhancement tools are used to optimize each image for printing on to 70mm film.
* Some of the techniques used to enhance the digital image include sharpening, colour correction, grain removal and eliminating unsteadiness.
* The enhanced digital signal is then recorded onto 15/70 film resulting in a visual presentation which, when projected on IMAX®'s projection system you have bright, crisp, steady and absolutely stunning images


DIGITALY RE-MASTERED, REFINED, AND RESIZED!

To create the brightness and clarity that audiences have come to expect from The IMAX Experience®, IMAX uses a proprietary computer program to make the images sharper than they were originally, while colors are adjusted for the unique technically superior characteristics of the IMAX screen. The completed re-mastered film is then transferred onto the world's largest film format, IMAX 15-perforations 70mm.


IMAX SOUND – CRYSTAL CLEAR AND FREE FROM DISTORTION

IMAX has always delivered incredible six channel multi-speaker sound that helps puts audiences in the picture. This experience is recreated for IMAX DMR releases. IMAX DMR recreates each film's original soundtrack, adding another sonic dimension to upgrade the original movie soundtrack to IMAX standards.

how do they manage aspect ratio of the original film when remastering like this? for example, 2.35:1 original (as in anamorphically shot on 35mm).
