In 2002, I remember seeing Apollo 13 at the IMAX theater in Universal City with a bunch of other HTF members during one of our first HTF Meets out in LA.
Yeah, I saw Apollo 13 at the IMAX at Loew's Lincoln Square in NYC via a SMPTE meeting invite. According to my notes, that was the first IMAX DMR and it opened in IMAX on 9/20/2002 (Wikipedia says 9/22) with 24 minutes cut out of the film, although I have to admit that whatever was cut wasn't noticeable to me. According to Wikipedia, the first IMAX film was "Tiger Child" released in 1970. "Live at the Max" was released in 1991. The 2nd IMAX DMR film was Star Wars Episode II, cropped to 1.85 and with 22 minutes removed.
