Original Cinerama screen in the Bellevue Cinerama, Amsterdam (1965–2005) 17-meter curved screen removed in 1978 for 15-meter normal screen. [1]Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146-degrees of arc.
Unlike other projectors of its hi-power kind, the DP70 did not offer forced-air cooling of the film itself, which is known to be a key feature to prevent overheating of the film and the major nitrate-fire prevention measure. A water cooled pre-shield just assists in keeping the gate and metal parts cold, not the film. [10]

35 mm movie projector in operation Bill Hammack explains how a film projector works. A movie projector (or film projector) is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras.
