Continuity: In one scene, Chucky and a girl are driving down a road when they get pulled over by a cop. The cop is surprised to see a "Good Guys" doll, and is shocked to see that its nose is bleeding. They do a close up of Chucky's nose, and blood is running from it. When they cut to the cops point of view, where Chucky and the girl are both in frame, the blood is gone. It doesn't reappear for the rest of that scene, even though no one wiped it away.
