Continuity mistake: After the worker has been electrocuted, Mattson and his boss walk towards the exit. We see Chucky sitting by the exit door (rigid and lifeless) and his right arm is down on the floor. In the next shot, his arm is in his lap. (00:07:35)
Continuity mistake: When we watch the production of the Good Guy dolls we see that the dolls get their hair stitched on while naked. However later we see dressed dolls come out of the machine with no hair on. It makes no sense that a factory would have two different production routines like that. (01:11:25)
Continuity mistake: When Phil stops the car due to nearly hitting a truck, the truck turns and drives along beside the car. The truck starts passing the car, but then as the shot changes, you can see out of the car window the same part of the truck passing the car once again. (00:09:50)
Continuity mistake: Near the beginning, Mattson tosses Chucky into the back seat of the car head-first. In the next shot, Chucky is turned around, as if he was chucked in feet-first. (00:14:35)
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: After the teacher has thrown Chucky into the closet there is a closeup of Andy. You can see a book with red edges on his desk. When it cuts to a shot from above you can see the book has changed. (00:34:15)
Continuity mistake: When the fire alarm has been set off, Andy is standing at the top of the staircase, looking at Kyle. Then Grace Pool walks down the stairs and grabs Andy by the top of his arm. But when the shot changes she is holding his hand. (00:58:00)
Continuity mistake: When Chucky closes the door so Kyle can't get in, he has his arm by his side, but in the next shot when he says 'Ok sport' his hand is up and pointing at Andy. (00:58:55)
Continuity mistake: When Andy is in the basement, he walks backward into the wash-dryer, and we see a big sheet hanging up on a line behind him, with five pegs. After he hears a noise and turns to look, now only four pegs hold it up. (00:43:15)
Continuity mistake: When Kyle manages to stop the truck, we see Andy running away with Chucky on his shoulders. It cuts to Kyle and the driver for a second before Kyle runs after Andy. In the next shot, we see Kyle running but we don't see Andy. Andy could not have run so fast that we wouldn't be able to see him anymore. (01:02:05)
Continuity mistake: When Andy is in the cellar it is quite dark. Then a round spikey object make some squeaky sound and Andy turns against it. When it cuts back to Andy the whole cellar is suddenly full of light. (00:42:45)
Continuity mistake: When Grace Pool is stabbed, she falls onto the photocopier, and Chucky falls to the floor, beside the photocopier. But in the next wide shot he's gone, with not enough time to of done so. (00:58:40)
Continuity mistake: When Joanne and Phil talk to Grace Pool about fostering Andy the pot of pens on Grace's desk move about between shots. (00:08:00)
Continuity mistake: The position of the metal poker changes from when we see it as the camera pans around the basement, to when Chucky picks it up. (00:42:25 - 00:45:10)
Continuity mistake: When Chucky jumps on Kyle's back in the bedroom, she struggles to get him off. In an attempt, she bashes up against the wall, and this knocks a picture frame askew. In the next shot the frame is straight. (00:52:30)
Continuity mistake: When Miss Kettlewell is stabbed with the bike pump by Chucky, she drops her keys to the floor. When Chucky exits the cloakroom with the ruler, the whole floor is visible, but the keys have vanished. (00:36:50)
Continuity mistake: The long ruler beside the classroom closet door keeps disappearing and then reappearing. (00:36:55)
Continuity mistake: The front part of Kyle's red Ford is damaged when she is trying to get rid of Chucky and smashes into a pole. However, when she runs to her car so that she can chase the Chicago Sun-Times truck, in the overhead shot of the front of the car as she reverses, the car is intact. (00:56:25 - 01:00:25)
Continuity mistake: When Kyle and Andy are climbing up the metal roller conveyer, in a wide shot when Kyle calls "Come on" to Andy, you can see Kyle is right at the top of the conveyer, but when the shot changes, Kyle isn't quite at the top yet. (01:06:30)
Continuity mistake: When Andy is being picked up by the manager of the center Kyle is standing in front of him. Then the manager calls for Andy, and Kyle is looking out at her. When it cuts Kyle is looking at Andy. (00:47:40)
