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)
Visible crew/equipment: When Andy goes upstairs after being introduced into the Simpson's home, he walks down the hallway and then backtracks to Kyle's bedroom door and opens it. As the shot pans closer in as he opens the door, the camera and its operator are shadowed on the door. (00:12:05)
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)
Audio problem: When Mattson throws Chucky into the back of the trunk, he tries to close the trunk. However, the trunk won't close because it hits Chucky. You can barely hear any sound when the trunk bumps into Chucky. When it cuts to Mattson trying again, you can hear a bumping sound. (00:14:35)
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)
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)
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)
Other mistake: At the beginning, we see the workers attaching Chuck's head to his body. But there's no place for the wires that would operate the dolls, seeing as how the workers believe he's just a normal doll.
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)
Plot hole: In the factory we see the machine that adds the hair to the Dolls it "punches" the doll at standing level. Andy hits the reverse button and they watch a doll go backwards. A few moments later Chucky appears on a cart and now the machine "punches" Chucky to the cart. 2 Errors -1 How did Andy and Kyle not see Chucky on the cart right in front of them. 2. What made the machine go low enough to stick Chucky to the cart.
Suggested correction: 1. Andy and Kyle were looking away, hence they didn't see Chucky. But then, Kyle turns and sees him. 2. We are to presume that the punch machine goes down until it is stopped by the doll it's meant to be "punching" into. So, it just descended until it reached Chucky and the platform he's on. (Additionally, the machine also seems to be malfunctioning given it goes into a sort of overdrive.)
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)
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)
