Abstract
A system for projecting and exhibiting motion pictures creating for the viewer illusory impressions of depth and participation. The system employs a single projector equipped with an anamorphic lens. In preferred embodiment the projector, using a standard 35 mm anamorphic film, projects onto a deeply curved screen. The arrangement is such that the system uniquely functions to produce good image focus over the entire surface of the screen to which the image is applied, lending a viewer a decidedly improved depth of perception.
