Continuity mistake: The sizes, locations, and smoothness of the pieces of glass remaining in the wall mirror after Aidan smashes it with a bat change. Initially, there were a few large and several smaller jagged-edged pieces around the top and upper-half of the right side. Later, there were four relatively large smooth-edged pieces spaced around the upper half of the mirror - one in each upper corner and one on each side at the middle. (00:15:48 - 00:19:33)
Continuity mistake: After the announcement from her boss that she is scheduled to 'marry' her quasi-fake BF, Ana goes to the gym to meet her friend. When they are talking, she says "it's been forever, it's already kind of worn out." Ana's ponytail is in front of her shoulder, and goes back behind her back in the next shot. (00:10:00)
Continuity mistake: Adam has connected strands of hair across his right cheek that are no longer there when the camera switches direction. (00:51:22)
Continuity mistake: At the "Wave Hair Salon", Ms. Gordon has a curler/roller at the top of her forehead. In some shots, it is straight, but in other shots it is angled. A little later, Christine goes over to Ms. Gordon and starts rolling down the curler to the top of her forehead as if for the first time. (00:08:04 - 00:08:47)
Continuity mistake: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff. After continuing the story for about two minutes, the length of the ashes still have not increased when Amanda is about to take the third puff. (00:37:21 - 00:39:53)
Continuity mistake: When Pat is standing on the passenger side of the flatbed near the rear bumper, the boxes are not covered in plastic. After Pat takes two steps and is behind the truck, the boxes are suddenly completely wrapped in plastic. (00:09:24)
Continuity mistake: Towards the beginning of the flashback, Jahkor gets thrown to the ground. The legs of the bully in the close-up cast a shadow over Jahkor's body. Cut to the next shot, and the shadow is away from Jahkor in a blatant change of direction of the light of the scene. (00:09:35)
Continuity mistake: There are some continuity problems during the cafeteria scene where Fern is being introduced to her co-workers. Fern is holding a banana, peeled almost to the bottom, and has several slices of banana on her peanut butter sandwich. There is another banana peel on her paper lunch bag. Fern is shown taking a bite of her sandwich. A little later, Fern is holding a partially peeled banana but no slices can be seen on her sandwich. If this is her second sandwich, she already peeled two bananas. (00:05:59 - 00:06:32)
Continuity mistake: When they lock Tommy in the port-a-potty, they put a sign on the door. The sign is crooked when he keys go off it. In the next cut, the sign is straight. (00:12:30)
Continuity mistake: Bernice's bangs go back and forth between having a small section separated from the rest to not separated. Before she kisses Thomas, her bangs are separated, but combed together when they are done kissing. (00:21:56)
Continuity mistake: Grandpa did not get a lot of soda/pop sprayed on his shirt or Santa hat - most went onto his face. However, the "wet area" of his shirt becomes much larger after he left the table. Not too long afterwards, the "wet spot" on his shirt looked much wetter, then soon after he falls down holding onto the ladder it's drier. Also, the white fur around his Santa hat stayed almost dry (or dry) despite being on his head when the soda/ pop (can shaken by Peter) sprayed all over Grandpa's face. (01:15:30 - 01:15:53)
Continuity mistake: The grilled cheese sandwich was charred while it was still cooking, but not when Jason's dad served it to him. (00:02:00)
Continuity mistake: After Wes was clobbered and on the floor, he had a long stream of water/mucus coming out of his nose or mouth and his lips were wet when he was standing up, but his lips/mouth/nose were totally dry when the killer put his gloved hand over Wes' right shoulder. (00:33:40)
Continuity mistake: Kareem's mom is talking to her coworker about the fact that her son asked for James to pick him up at school. When she mentions that it's not seen as the coolest thing to date a cop, and a white one at that, her friend goes from hand low, to smoking with that hand, to drinking from the cup, in the span of a few words and a couple quick cuts. (00:09:45)
Continuity mistake: Yi-Na had her head turned to the right while her dad Sang-Won was talking to her from the front seat and, eventually, Yi-Na closed her eyes. After a camera shift, Yi-Na's eyes were still closed, but her head was turned to the left. (00:04:17)
Continuity mistake: At the restaurant, the chairs at the counter behind Mara and Tess get turned sideways a few times even though no-one is moving them. (00:08:36 - 00:09:19)
Continuity mistake: Theodore rides once the tiny rollercoaster; the cart comes to a full stop and his left foot is in the space between the bars, but in the next shot the left foot is on the outside. (00:48:00)
Continuity mistake: There are only two missing pieces to complete the jigsaw puzzle, and the perimeter/frame is intact. After the pastor turns the puzzle around to face Eden, there are four pieces missing, three of which are perimeter pieces. (00:04:38)
Continuity mistake: The amount and location of dirt on Christine's face is inconsistent, ranging from being very thick and obvious to barely visible, if at all. Sometimes it extends down her neck on the right side. When her hair covers most of her face, no dirt is visible - until she turns her head and the hair is away from her face. The intensity and location of the redness on her neck also varies. (00:03:31 - 00:04:48)
Continuity mistake: Brahms was quite clean for having been buried under dirt and leaves. No dirt fell off Brahms' body when Jude pulled him out of his "grave" and there did not appear to be dirt in his hair. When Sean (Jude's father) held up Brahms, the doll looked relatively clean - or cleaner compared to when Liza (Jude's mother) started to wash him. (00:14:10 - 00:15:45)
