Saving 35mm prints goes beyond the movies as well. I read a story last year concerning the rock band Black Sabbath. Apparently when Dio was singing for them in the early 80's they filmed one of their shows for eventual release. There were a dozen or so canasters of 35mm film done. Well when Dio left the band there were apparenlty hard feelings and they decided to literally dump the project and they threw away all of the film. A collector rescued all of the canasters from the trash and they are still in the hands of a private collector to this day. Legal issues prevent them from distributing it.
