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.
