Night of the Demon/YMMV


 * Hell Is That Noise: If you hear creepy bat-like chittering, your time is almost up.
 * At a certain speed, this troper's vehicle makes the exact same noise from its vents - kind of scary.
 * Special Effect Failure: The closeups of the demon are more likely to inspire laughter than terror. Other effects, however, are really pretty good.
 * The closeups were a result of Executive Meddling - director Jacques Tourneur wanted the demon to be barely glimpsed. The demon's smoky long shots are effective, though.
