A floating alien brain possesses a man and turns an ordinary small town setting into a test of appetite and control. The Brain from Planet Arous makes the invisible takeover visible through altered behavior, abrupt threats and a strikingly literal monster. Its economy is part of the fun: cosmic stakes arrive in domestic rooms rather than a vast futuristic city. Watch the contrast between the man's familiar face and the alien's increasingly open enjoyment of the power that face allows it to exercise.
