Revealing mistake: When Mattson pulls the card through the card reader in order to open the door, there is no lock mechanism on the door at all when we see him opening the door and entering the room. (00:04:45)
Revealing mistake: After Phil has thrown Chucky down to the basement he turns the lights off. We then see lights fading in to make it seem like light is coming from outside the window. (00:30:20)
Revealing mistake: When Miss Kettlewell is searching in the closet for Andy, you can clearly see shadows of crewmembers moving about on the hanging coats and walls, on the left hand side of the screen. (00:36:20)
Revealing mistake: When Andy first goes down into the cellar with the electric knife, the camera pans around the cellar, then back to Andy. When Andy starts to walk away from the foot of the stairs, you can see a cameraman's shadow on his back. (00:41:35)
Revealing mistake: When Joanne is kneeling by Phil's body, she cries "Oh God no." and then, just before it cuts, Phil's right hand moves, even though he is dead. (00:45:50)
Revealing mistake: In the full-screen version, a piece of Chucky's animatronic equipment can be seen bobbing up and down with him (the bottom-left corner) as he chases Miss Kettlewell in the classroom.
Revealing mistake: When Grace falls to the floor, copies of her face keep pouring on her. Two are shown up close pouring out, and they are different from each other. One has a big hole of cracked glass covering her right eye and the other one shows her right eye without the hole at all. One copy was taken before she fell so two different looks over her eye is not possible.
