Trivia: When filming the scene where Marty is being hanged from the clock tower, Michael J Fox agreed to really hang from the rope. Whilst filming, Fox held the rope away from his throat with his hand. At one time he wasn't holding the rope and was really being strangled.

Trivia: When the movie played in theaters, there was a scene where Dr. Catheter begins to tell Billy about the gremlins before the movie is interrupted by gremlins until they are threatened by Hulk Hogan.

This caused many people who bought or rented the movie to think there was something wrong with the tape and took it back to the stores they purchased it from.
