I've also heard Cameron has stated that he prefers the full frame version of his movies. Was super 35 matted used for LotR? Is there a list of all of the matted widescreen films where you actually see "more" in the fullscreen version. Didn't the dvd lawsuit against MGM deal with this? The open matte films I can think of are.
