There is a saw laying on the floor from the "Good Guys Tool Box Set" which disappears between these two shots as well. (00:15:25)

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.

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: 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.

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 Chucky peers through the window of the institute, he sees the keys on the table. The black telephone on the table moves from being against the wall, to sitting out halfway on the desk between shots. (01:04:25)
Continuity mistake: Karen threatens to throw Chucky in the fireplace if he doesn't speak, and then suddenly Chucky comes to life and starts to thrash and kick in Karens arms.

Continuity mistake: The drink Andy makes changes colour.
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: 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.
