Continuity mistake: When Judge Reinhold is in his kitchen with Helen Slater he tells her they have to be ruthless. He sees a spider on the floor and gets a magazine and scoops it up. Then he goes outside to let the spider out and he puts the magazine down for 1/2 of a second. He was supposed to put the spider on the ground but if you look nothing comes off the magazine. Then he goes to squash it with his foot, but what can he squash if there's nothing there? (00:13:35)
