Continuity mistake: The toys in the back seat of Mattson's car change from when Chucky is tossed in, to when Chucky comes alive. (00:14:45 - 00:16:05)
Visible crew/equipment: When Mattson gets in his car, you can see a crewmember wearing a yellow raincoat reflected in the car door, along with what looks like camera equipment. (00:14:50)
Continuity mistake: At night when Mattson is leaving the factory, it's raining and he tries to put Chucky inside the trunk, he can't so he grabs Chucky by the face (near its eyes) in the next shot Mattson is holding Chucky by its clothes. (00:15:20)
Continuity mistake: When Chucky is threatening Mattson in the car with the fake gun, between shots as he shouts threats at Mattson, Chucky's grip on the gun and the angle at which he has it pressed against Mattson's cheek keeps changing. (00:18:30)
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 pretends to be Tommy, a small drawn on mole, under the left side of the dolls' mouth is alternately there / missing. The position of the dolls' hair keeps altering as well. (00:25:00)
Continuity mistake: When Andy approaches Chucky posing as Tommy, near the foot of the stairs, the doll's freckles are faded in some shots, and more prominent in others. (00:25:00)
Continuity mistake: In the first movie, when the batteries fall out of the Good Guy box, they are size D. When Andy goes to check the batteries in this movie and opens Chucky up, the batteries are marked size C. (00:26:00 - 00:27:00)
Visible crew/equipment: When Kyle is gardening outside, a crane is on her left. Watch carefully and a shadow moves along it. It could not be a cloud making the shadow as none of the other shadows disappear. Something or someone are making those shadows; it's either a crew member or some equipment. Kyle and Andy are supposed to be alone in the backyard. (00:26:15)
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: When Andy is tied up on his bed, the two skipping ropes tied to his feet have green rope, but in one closeup of Andy kicking his foot about, the rope is yellow, then in the next wide shot, is green once again. (In the closeup of Andy kicking his feet he has also gained slippers!) (00:28:35 - 00:29:40)
Continuity mistake: When Kyle climbs into Andy's room, she unties his hand from the skipping rope, and Andy punches Chucky, who falls down onto the floor by the side of the bed. Yet when Phil comes in, he picks up Chucky from the floor by the end of the bed. (00:29:30)
Continuity mistake: After Kyle takes the sock out of Andy's mouth, she places it on the bed. In the next shot it has gone. (00:29:40)
Continuity mistake: Look at Andy's feet when he was freed when Kyle comes in through the window, he has no shoes on, but when he chases after Mr. Phil Simpson he gains a pair of shoes. (00:30:00)
Revealing mistake: After Phil has thrown Chucky down to the basement he turns the lights off. We then see lights fading in to make it seem like light is coming from outside the window. (00:30:20)
Continuity mistake: In the very first shot of Miss Kettlewell reading, in the background beside the closet is a ruler leaning against the doorframe. When Miss Kettlewell walks to Andy the ruler is now leaning upright against the wall, no longer leaning on the doorframe. (00:32:40)
Continuity mistake: The books and other items on the desk of the boy sitting behind Andy move about between shots, and the boys sleeves change from rolled up his arms to pulled down to the wrists too. (00:33:00)
Continuity mistake: When Miss Kettlewell is reprimanding Andy in class for disturbing her lesson, the shot alternates from behind her to in front. During each shot change, the position of the book she clutches in her arms keeps changing. (00:33:10)
Continuity mistake: When Miss Kettlewell is about to check the children's homework sheets, she puts her glasses on. Then when she discovers the profanity written on Andy's work, you can see her glasses hanging down by her chest. They're back on in the next shot. (00:33:35)
Continuity mistake: In Miss Kettlewell's classroom Andy slides open a cupboard door and sees Chucky. He only opens the door about halfway, but in the next wide shot, the cupboard door is slid all the way open. (00:33:40)
