Continuity mistake: When Andy equips himself with an electric knife, he heads for the basement, opening the door. We then see a shot of the basement, completely dark except for a window-shaped patch of light. When Andy gets down the stairs, the basement is much more brighter. (00:41:10)

Continuity mistake: When Kyle has dropped the knife to the floor she is standing by a mirror looking down to her right for the knife before reaching for it.

Continuity mistake: 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. (00:54:55)
