Continuity mistake: Towards the end, when Frank is about to kill the tied up Pauly Shore and Tia Carrera, he has a plastic glove on when his hand is raising the knife. When he drops his hand to his side and you get a different camera angle, he is not wearing the glove anymore.
Continuity mistake: When Pauly Shore is driving the truck full of Styrofoam towards the end of the movie, the level of Styrofoam changes from scene to scene. First it is full, then half full, then full again.
Continuity mistake: At the end when Tommy hits Frank with the book, Frank lands on the broken railing so that most of his body is on the railing, including his stomach and one of his legs. You also see the knife fly away from Frank's hand and past the top wooden part of the railing. In the next shot, only a little bit of his body is on the railing and the knife is on it as well.
