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.

Trivia: Reportedly, star Kevin Bacon was at a rough patch in his life during production and didn't understand the appeal of the film or the light-hearted comedic elements. (Even once breaking down in public and exclaiming in frustration "I'm in a movie about giant underground worms!") And thus, he chose to have no involvement in the sequels. It wasn't until some years later that he decided to re-visit the film and give it another chance after it became a massive cult-hit, and discovered that he actually really loved it. Bacon has since gone on record saying one of his dream projects would be to reprise his role of Val McKee in a future film.
Trivia: The third story, " A Lovers Vow" was based on the Japanese folklore of the yuki-onna. However, writer Malcom McDowell decided that the creature should be a gargoyle instead of a spirit.
