Trivia: When Jennifer Aniston answers the phone and the Leprechaun's hand comes out, it's an homage to the scene from A Nightmare on Elm Street, when the main character was talking on the phone and it suddenly turned into Freddy's mouth and tounge.
Trivia: When Max is chasing the cat, the scene was accomplished by training the cat and dog together so they'd be comfortable. The cat was being trained to run towards a toy, while the dog was trained to run towards a trainer making hand signals a short distance away from the cat-toy. If you pay very close attention, there's actually one point in the scene where you can tell that they're running in ever-so-slightly different directions.
Trivia: The initial cut of the film came in at under one hour. Original director William Lustig refused to shoot any new scenes and walked away from the production. Joel Soisson was brought in to direct several new scenes to pad the film out. Additionally, outtakes and clips from "Maniac Cop 2" were also spliced into the film to lightly pad the runtime.
Trivia: This comedy features several future stars. It was the feature film debut of Matthew Fox of "Lost" fame and superstar Matthew McConaughey (albeit in a very small role). It's one of Philip Seymour Hoffman's earliest movies. And it would have also been Renée Zellweger's feature film debut, but her scene was cut before release.
