Continuity mistake: The position of the spilt flour on the floor differs from when the camera first pans to it, to when Maggie gets the broom and dustpan and begins to clean it up. (00:21:45 - 00:22:50)
Continuity mistake: When Andy is making his mum breakfast in bed, there is a glass of orange juice on the breakfast tray. During shots in the scene, the amount of juice in the tray changes. As he carries the tray to his mum's room, he keeps spilling juice out of the glass, yet in following shots the juice is either at the same level, or is even higher than before, etc. (00:08:15)
Continuity mistake: When Karen and Maggie go to the peddler in the back alley, as they approach the peddler, the large dumpster behind the peddler has it's lid halfway open. Yet when it cuts to them reaching him, the dumpster is closed. Cardboard boxes piled up to the left of the dumpster also appear between the same shots. (00:11:30)
Continuity mistake: When Karen and Mike Norris talk in the graffitied room, and Mike tells Karen information about Chucky, in every back shot of Karen, a black handbag strap hangs on her left shoulder, yet in every front shots it isn't there. It appears/disappears/reappers several times. (00:58:40)
Revealing mistake: In the scene where Andy's aunt is sitting on the couch and Chucky runs by, look closely, you can see it's not Chucky but it is a person. (00:19:35)
Continuity mistake: When Karen and Detective Norris arrive at Johns home, Karen runs to John, who is lying on the floor, bleeding, and she kneels down to speak to him. In one shot, she kneels and her arms are by her side and her handbag hangs over her left shoulder. It cuts and now her left hand is resting on Johns neck, and her handbag has disappeared from her shoulder. (01:02:45)
Continuity mistake: As Andy talks to Dr. Ardmore through the bars in the door at the institution, sometimes Andy's right hand is gripping the wooden door, sometimes not. (01:03:55)
Revealing mistake: When Mike is in the car being attacked by Chucky, after he hits a metal can and makes sparks, he swerves violently in the road, and on the road you can see several pairs of dark skidmarks in the exact same place as he swerves, obviously from previous takes. (00:55:15)
Continuity mistake: When Andy makes his mum breakfast, he puts burnt toast onto a plate then puts a big lump of margarine on a slice of toast. Then when Andy pulls the tray from the counter, the margarine rolls off the slice of toast, onto the plate. Then when Andy walks to his mum's room, the margarine has jumped back onto the slice of burnt toast. (00:08:15)
Visible crew/equipment: At the end of the film, the burnt head and body of Chucky are thrown across Karens bedroom, below the window. The body twitches, then suddenly jumps up. The body's (one) leg actually doesn't touch the ground! The body rises with no real support, so if you look under the body, you can see a black rod/sheet (coming from through the carpet), pushing the burnt body up. (01:21:50)
Continuity mistake: When Aunt Maggie goes to pick up Andy and take him to bed, the cushion on the couch that Chucky is propped against, goes from sitting upright against the arm of the couch, to laying down on the couch between shots. (00:15:25)
Revealing mistake: Look very closely at the way Maggie is knocked backwards after being struck with the hammer. It seems as if she is deliberately throwing herself backwards, which also means they may have used reversed footage.
Other mistake: The Good Guy dolls are said to be manufactured by the Play Pals toy company. Later, when Karen picks up the box that Chucky came in, on the bottom left corner of the box are the words Play Partners Toys.
Continuity mistake: When Karen throws away Chucky after he bites her, behind her are 4 pokers that become 2.
Continuity mistake: When Maggie goes to pick Andy up and take him to bed, she walks over, and there is a box on the floor. In one shot she stands with one foot either side of box, standing over it. It cuts and the box has now moved to being beside her, and she no longer stands with it in between her feet. 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: When Karen talks to John as he's dying on the floor, sometimes Johns hand is on Karens arm and sometimes it isn't. Also, Johns hands are covered in blood, yet when he touches Karens coat no blood is there in following shots. (01:02:45)
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: When Dr. Ardmore is trying to give Andy the injection, the syringe he has is in his left hand, then disappears when he tries to take Andy's coat off, then reappears in his right hand. (01:06:30)
Continuity mistake: When Dr. Ardmore tries to give Andy the injection, Andy struggles from his grip and then grabs his glasses from his face. Then in the next shot of him, his glasses are back on his face. In the following shot they've gone again. (01:06:45)
Other mistake: Being struck on the forehead with a toy hammer would not cause someone to be knocked off balance to the point that they are flying backwards the 15-20 feet or so we see with Maggie.
