Continuity mistake: When Chucky is electrocuting Dr. Ardmore, blood comes out of his mouth and eyes. Yet when Dr. Ardmore finally dies, there is no blood on or around his eyes. (01:07:15)
Continuity mistake: After escaping from the institute, Andy goes back to the apartment. When he gets through the front door, he picks the big blue rug up from the floor and tosses it to the right of the door in a heap, then drags a bench and pushes it against the front door. Yet later, Karen and Detective Norris arrive at the front foor, then smash through it. When they smash through it, Norris rolls to the floor and you can see the big blue rug now laid out perfectly in front of the door. (01:08:25 - 01:12:45)
Continuity mistake: When Andy returns to the apartment, he goes to his room and shuts himself in his spacious cupboard. In the cupboard there's a pile of toys including a red remote-control car, a baseball bat etc., and between shots the pile of toys changes. Eg. when Andy looks at the pile, the baseball bat is totally exposed, yet when he picks up the remote-control car the bat is wrapped in a sweater. (01:09:35)
Continuity mistake: In Karen's apartment, Mike Norris gets slashed on the back of his leg, well below his knee, by Chucky with his knife. Yet later in Karen's room, Mike makes out as if the cut is well above his knee, and that is where his leg is bandaged. (01:12:55 - 01:21:40)
Continuity mistake: In the apartment, Chucky nearly transfers his soul into Andy, until Karen and Mike come and save Andy. Karen then takes off her coat and puts it over Andy, who lays on the floor. In a wideshot, when Mike gives Karen his gun, the coat lays about halfway up his body, yet when it cuts to a closeup we see the coat laying over his body all the way up to his neck. (01:13:10)
Continuity mistake: When Mike Norris opens Karen's bedroom door, looking for Chucky, the camera pans around Karen's room and on top of her TV you can see a wicker basket, some books and a vase. Yet later when Chucky finally gets into the bedroom and chases Karen and Andy, and in following scenes, the vase has gone from the top of the TV. (01:13:25 - 01:18:20)
Continuity mistake: In Karen's bedroom, when Chucky is shot in the leg he flies near the window, and there is a dresser table right beside the window. But minutes earlier, when Mike entered the room and the camera panned around the room, the dresser table was a couple of feet away from the window. (01:13:30 - 01:14:15)
Continuity mistake: After Chucky is set alight, as he knocks down the fireplace guard you can see both his shoes have come off. In the following shots as he climbs across the sofa, his shoes are back on. (01:15:35)
Continuity mistake: Karen, Andy and Mike are shut in Karen's bedroom and Chucky has the opportunity of getting into the bedroom via two doors - a door leading to the hallway, or a door leading to the bathroom. The door leading to the hallway has a key in it, on the side of the door facing INTO Karen's bedroom. Yet later, Chucky runs down the hallway facing the outside of Karen's bedroom door, and first there is no key in the keyhole. Yet when Chucky smashes the door open, there is now a key in the keyhole on the outside of Karen's bedroom door. (01:17:20 - 01:18:15)
Continuity mistake: When Karen struggles to keep the door shut, as Chucky tries to pull it open, Chucky stabs his knife through the door, cutting Karen's hand. Between shots the hole made by the knife gets mysteriously longer, and all the holes Chucky makes in the door seem to change shape/size/location. Also, when Chucky stabs through the door, cutting Karen, a small stain of blood is left on the door. Between three consecutive shots the blood is there, then disappears then reappears. (01:17:45)
Continuity mistake: When Chucky's fried, decapitated body comes out of the vent and grabs hold of the policeman's neck, the policeman whirls around and knocks a basket and another object off of the TV. The shot goes to the other three, but when it goes back to Chucky and the cop, the items are back on the TV, untouched. (01:21:20)
Continuity mistake: When Chucky is finally shot at the end of the film, his body falls to the floor, slanted on it's side and then dies. Yet seconds later when Andy looks at the remains of Chucky, Chucky's body is now sitting upright against the wall. (01:22:05 - 01:23:10)
Continuity mistake: At the end, when Andy's mom shoots Chucky for the first time, it doesn't really faze him; he just keeps walking. But in the bedroom, when she shoots him through the heart, the bullet impact causes him to fly several feet through the air.
Suggested correction: Because shooting him in the heart is the only way to kill him, also when Mike Norris shot him he got sent flying, but when his body parts get shot off he still walks.
It has to be a human heart in order for him to die, that's what the man told Karen.
Continuity mistake: When Karen throws away Chucky after he bites her, behind her are 4 pokers that become 2.
Continuity mistake: The drink Andy makes changes colour.
Continuity mistake: When Andy makes his mother breakfast in bed he brings in a glass of orange juice but over the course of the scene of him and his mother talking it changes to a much lighter colour. It could have been switched with a glass of milk or cloudy lemonade but it's probably just the same orange juice that's been watered down over multiple takes.
Continuity mistake: After the cop helps Karen she has a bunch of snow on her back which decreases between shots.
Continuity mistake: While Andy is playing with Chucky and the wooden car, there are some tools that disappear and reappear between shots.
