A motion picture apparatus and method for intermittently advancing motion picture film by forced air. The film is initially placed into successive loops formed by closure of a rotary air valve. The loops and thus the film are advanced through the projector or camera pathway by a forced air blower which propels the successive loops through a projection pathway by opening of the rotary air valve. The film loop is metered by timing the opening and closing of the rotary air valve with the opening and closing of the shutter of the motion picture apparatus.
