When the film ends, we suddenly see the credits scrolling up on a completely different movie screen, together with another completely different cinema audience of onlookers observing it before getting up and leaving one by one until the final onlookers stand up and walk to the left with the screen going black as he/she does so (implying that the real storyline was also yet another film within film).
The film begins with a written disclaimer: "During the film you are about to see, you will be subject to subliminal messages and mild hypnosis. This will cause you no physical harm or lasting effect, but if for any reason you lose control or feel that your mind is leaving your body -- leave the auditorium immediately." The disclaimer is accompanied by a narrator, who advises viewers to take caution regarding their surroundings once the film has begun, and not to engage in conversation with any unknown individuals for the duration of the running time.
