Continuity mistake: When Kyle first breaks the car, and Chucky flies out the window, behind the wire fence you can see loads of barrels and crates. But when Kyle smashes the car into the fence in an attempt to hit Chucky, in a wide shot you can see all the barrels and crates have fallen over, but there are less barrels and crates than in the previous shot. (00:56:15)
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 the fire alarm has been set off, all of the children run down stairs, and at the end of the line of children, we see Andy who stops at the top of the stairs. When he stops you can see a girl holding a teddy going down the stairs, and she is nearly reaches the bottom. But when the shot changes, the girl is nearly at the top of the stairs again. (00:57:50)
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 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 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 Grace falls to the floor dead, photocopies fall over her body and face. But when Kyle opens the door and sees her, there are no sheets of paper on her face anymore, just two sheets on her body. (00:59:00 - 00:59:55)
Continuity mistake: In one wide shot as the fire trucks drive down the road, it is apparent that Kyle's red ford, which she crashed earlier, is not there. It should be partially visible in this shot, yet isn't. (00:59:20)
Continuity mistake: When Kyle is pursuing Andy and Chucky, she sees them climbing onto a truck which drives off. The truck is several feet away from Kyle and while it is driving it passes by a fire truck. Kyle start running after the truck and when it cuts she is right behind the truck and the fire truck is not to be seen anywhere. (01:00:00)
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 Kyle is running after Andy against the factory, we see Andy approaching a huge truck. However Andy passes the truck several times between the shots. (01:02:20)
Continuity mistake: Street goes from wet to dry, as Kyle runs toward the closing metal door at the Play Pals factory. (01:02:30)
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 Chucky is pursuing Andy up the slide we first see Chucky all they way down on the slide and Andy half way up. When it cuts Chucky is suddenly at Andy's feet. (01:07:00)
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: At the beginning of the film the facial features of the doll are sprayed on using a mask with cut out sections. There is no paint sprayed on the 'eyelashes' part of the mask, and when the mask is removed the doll has no eyelashes. Chucky, however, does have eyelashes throughout the rest of the film.
Continuity mistake: In two different places in the movie, Andy's foster parents have the same argument with the EXACT SAME dialogue, about Andy being too much to handle. Obviously, the director decided to try the dialogue in two different settings, and both scenes were accidentally left in.
Continuity mistake: In the opening montage, when Chucky is rebuilt, they show his shoes being tied. About a minute later, when the CEO and his assistant enter the room, you can see one of the tech guys tying his shoes in the background... even though they were already tied.
Continuity mistake: The first shot of the movie is an extreme closeup of Chucky's eye. Two shots later, you get a view of his whole face... and his eye is completely different. The color and design is slightly different, and the charred plastic around it doesn't match. The scene was shot with two different props (an oversized eye for the extreme closeup as confirmed in the commentary, then a regular sized doll-head for the next shot), and they didn't quite match.
Continuity mistake: When Kyle pulls her car in front of the big truck with all the newspapers in back, the car is first shown curved at an angle, but after a camera change to a different angle, the car looks straighter in relation to the truck and not blocking it in the same area.
