I did enjoy watching the third Matrix release in IMAX. My opinion of the audio was favorable in that it seemed less strained in those portions that required high output, and that would make sense based on IMAX system specs.

Speaking of screen images, there is a large screen theater format, not as widely known as IMAX, by a company called Showscan in Culver City, CA. Their film production is meant to accompany motion rides. They not only use 70mm film, but they shoot and project at 60 frames per second instead of 24 for ‘flicker-free’ viewing. More expensive film stock and more of it, not something likely to be used for feature films. Then again, no ‘pull-down’ needed for needed for regular television and transfer to HD is a one-to-one ratio.
