Continuity mistake: Opening scene where Chris Sarandon is chasing Brad Dourif into the toy store. During the gunfight, Sarandon has gloves on. As he enters the store he is wearing gloves. The next shot, the gloves are off. The next scene, the gloves are back on and he takes them off by biting the fingertips and pulling them off.
Continuity mistake: When Andy pours the cereal, and then the milk, there is cereal on the counter, to the left of the bowl. There is loads of cereal on the counter, then when Andy puts the burnt toast onto a plate, there is much less cereal. Then when he takes the tray from the counter, there's now loads of cereal on it.
Trivia: In all, nine menacing Chucky figures were constructed for the film: a simple "toy" doll; a doll that could stand upright; a doll that could walk; two hand-held puppets for quick, specific movements (such as sitting, biting or flailing about); and expendable "stunt dolls" that could be tossed round the set or otherwise subjected to rough treatment.
