Trivia / Ghoulies IV

• Creator Backlash: Script writer Mark Sevi has gone on to say that he hates the final product, and that his script got rewritten by Liapis and Wynorski so much that he felt his listed credit was him being scapegoated.
• What Could Have Been: The puppet Ghoulies were supposed to come back for this film; However, Cinetel Films didn't have the money to rent them for this film, causing them to just stick with the actors.
