I didn't comment on the film used, did I?
I told where and when I saw it. The 'where' WAS on a 'Cinerama' screen. Obviously the projection unit was so positioned that the movie's aspect ratio and screen size overarched the audience's entire periphery (or at least those I can speak for, sitting front and center), and caused the visceral *weightless* effect of which I commented. The point I made was on the 'frame' visible around what one views, and its negative effect on the 'willing suspension of disbelief'. When the frame is removed (as with sitting at the very front of an incredibly wide/tall screen), so-called 'immersion' can ensue---of a deeper, more total type than '3-D' of any stripe can produce. Thanks for the note.
