I was reading somewhere that Lucas or Spielberg was working on a film that had twice as many frames per second as normal. They said that the more you increase the number of frames per second the more reaction and emotion the audience feels. They assimilated the effect as the same as the brainstorm type tape. The idea wouldn't go over big because of the cost of replacing all the projection equipment and the amount of film needed, but it might be good for certain areas. Any info on this subject would be appreciated. thanks, craig You almost got it right. The projection system is called "Showscan" and is being pushed by Douglas Trumbull. The frame rate is 60 hertz and the film format is 70mm, but a 35mm version exists. Interesting you should make the comparison to the tapes in "Brainstorm". That film (produced by Trumbull) was originally intended as a vehicle for the introduction of Showscan to the theaters. The idea was that the "brainstorm device POV" scenes would be in 70mm 60hz Showscan, and the mundane world view would be done in 35mm 24hz format (printed up to Showscan). As it was, that project could not get funding and the concept became to switch between "Academy Apreture" and widescreen format. -c
