A movie projection system includes a film projector for projecting moving images of a film while broadcasting the film sound track in two or more languages simultaneously to different film viewers who view the film at the same theater. A time code reader detects time code signals recorded on the film and derives sync signals therefrom. A playback system receives the sync signals for generating first and second sound tracks, in first and second languages, respectively, each synchronized with the images recorded on the film. The first sound track is broadcast over the usual theater sound system, while the second sound track is transmitted to receivers worn by those viewers who speak the second language.
