Alfred Hitchcock's famed experiment creates the illusion of a single-take film by splicing each 10-minute single-take reel with hidden hard cuts. Watch it for his daring 1948 innovation in apparent "real time" filmmaking, much later to be explored in films like Russian Ark and Birdman, or for the stagy but deeply sinister murder plot: Two students kill a third for the thrill of it and invite the victim's family to dine off the chest that hides the corpse.
