Abstract

An embodiment of the invention provides a theater having a first screen and a second screen movable relative to the first screen. The first and second screens are typically designed for different movie formats. The second screen is mounted to a frame in sections, and a rotating member is operable to move sections of the second screen away from the first screen. A projection system disposed in front of one of the screens is operable to project screen images alternatively on the first screen or on the second screen. A plurality of speakers are mountable to the frame to provide a sound system.
