Visible crew/equipment: When Andy goes into the closet and he knocks the skateboard, and Chucky falls down, you can see a wire attached behind the skateboard so it doesn't fall down on the actor. (00:13:55)
Continuity mistake: When Joanne is singing to Andy during the thunderstorm it pans to the banister to show Chucky standing at the foot of the stairs. In this shot Chucky tilts his head to his left. In the immediate close-up his head is tilted to his right. (00:21:15)
Continuity mistake: When Chucky walks out of the closet saying "You've been very naughty..." there is no gap between the clothes hanging on the rack behind him, where they were pulled apart previously by Miss Kettlewell. In the next shot, there is again. (00:37:00)
Visible crew/equipment: When Mattson and his boss enter the room where the Chucky doll is being made, at the beginning, there is a boom mike reflected in the glass panel next to the door, as they enter the room. (00:04:45)
Continuity mistake: Throughout the classroom scene, there is a row of desks which are right by the wall, which keep either disappearing or moving. (00:34:40)
Deliberate mistake: When Andy opens the tap to the liquid plastic it is that some of the liquid squirts on his hand. That would hurt and stain, but Andy doesn't seem to care... (01:14:35)
Continuity mistake: When Kyle and Andy are in the garden, we see Chucky sitting on a flower cart. In a wide shot he sits in the middle of the cart, in a closeup he's on the left. (00:26:40)
Continuity mistake: In the school cloakroom above the coats, is a shelf of dodgeballs, footballs and basketballs. Look at the arrangement of the balls when Miss Kettlewell enters the cloakroom. When Miss Kettlewell is stabbed, and crashes into the desks, you can see in the cloakroom that the arrangement has totally changed and additional items have appeared. (00:36:25 - 00:37:05)
Other mistake: When Andy is in the Chucky Factory at the end, the boxes momentarily knock him out, as the camera is on him, you can see that his eyes are blinking when they're shut.
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: When Ms. Simpson and Andy enter Kyle's room, Kyle's lighter is lying on the table beside the cloth. When they leave, the light has moved onto the cloth. (00:12:30 - 00:13:00)
Continuity mistake: Near the beginning, the Chucky doll causes a worker to be electrocuted and fly backwards. As he somersaults through the air, and through the window, it is clear that in this angle he will land on his front. But in the next shot we get a close-up of him lying on his back. (00:05:55)
Continuity mistake: When Kyle has dropped the knife to the floor she is standing by a mirror looking down to her right for the knife before reaching for it. It cuts to a closeup of the knife and Chucky grabs it before her. It cuts back to Kyle who gasps in fear, but now she is looking more to her left like everything is happening on that side. (00:52:50)
Visible crew/equipment: After Andy has came back from his school, Phil and Joanne are arguing in their room about Andy and his problems. Then there is a travelling shot of the wall in direction to Andy's room, in the travelling shot there's an old black and white photograph (6th) of a woman which reflects the movie camera man and one of his hands while Phil says "For whom Joanne? For him?" (00:40:35)
Continuity mistake: Miss Kettlewell gets stabbed, and goes flying out of her cupboard. As she flies into the desks and falls she is wearing tights, but in the previous shots she wasn't. (00:36:55)
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)
