CinemaScope is a system of making and presenting motion pictures including in the theatre an anamorphic lens for expanding the projected picture horizontally, a curved or concave screen of special design, an additional, simple, film-driven sound head designed to pickup the multiple magnetic tracks of the CinemaScope system, as well as a multiple installation of amplifiers, speaker assemblies and allied equipment designed to produce stereophonic sound, which latter might be described as sound seemingly actually to originate at its visual source upon the picture or, as respects effects, from some source entirely outside the limits of the picture.
