Man I saw that in a theatre in SD, it was really great, but it was possibly the worst projection I've ever seen, and it just about ruined the movie for me. Every reel had *radically* different color timing, so you'd be watching one scene and then it was almost as if someone screamed "MAGENTA" directly in your ear. And then the next reel would be yellow, etc.
It's also interesting because the possiblity of a doing a feature-length film in one take has been made possible only recently (really). I don't think anybody ever made a 1500 ft. reel of 35mm film or whatever you'd need to do an hour and a half of film....So yay for Digital Video.
