An audio-visual cassette system is provided employing a photographic film strip and an audio tape interwound on a common supply spool and adapted to be advanced along different paths from the supply spool to a takeup spool. The cassette is of the type in which the film strip may be exposed, processed and projected for viewing without removal from the cassette. The film strip is provided with an aperture in the supply spool leader which cooperates with a processor actuating pull strip to initiate processing of the film upon film advancement. The audio tape is coupled to the film strip at the supply spool end at a location with respect to the aperture such that the film strip pulls the tape away from the aperture region of the film during engagement of the pull strip with the aperture.
