Visible crew/equipment: In the scene where Jenny's former boyfriend shows her the broken cupboard-door a crew member is reflected in the window over her right shoulder.
Continuity mistake: When Vivian comes out on the porch with a bottle of soda, the level is way under the label. When she goes down the stairs the level is way over the label on the bottle. (00:42:30)
Audio problem: DVD version. In the scene where Lisbeth is about to be buried alive, she gets shot three times by her father as she tries to run away. The sound effect of the gunfire includes the tinkling of a spent cartridge hitting the ground (clearly heard in the rear right). However, the father's gun is seen to be a revolver, which does not eject spent casings when fired - the spent casings stay in the cylinder. (01:50:30)
Factual error: The scene where Princess and Steven are in Chrome Skull's truck, they are trying to dial 911. They are denied access because the phone is password protected. This would never happen. Even though there is a lock on the phone, it would be automatically deactivated for 911 calls. When you lock your cell phone to protect it from unwanted usage, the phone will deny all usage EXCEPT 911 calls.
Continuity mistake: During the song 'Video Girl' watch Nick's tie because the tie is on, then it's off, then on again, then off and so on. (00:23:35 - 00:28:00)
Continuity mistake: When Sugar Bear flies through the air and lands on Truck at the end dance off, Trucks legs bend backwards underneath him. When Sugar Bear gets off of him, he's now flat but his legs are laid straight out instead of bent.
Continuity mistake: Lyn has a patch on his nose and it's loose on one side. In the next scene it's attached tight to his nose again. (01:17:00)
Factual error: Kevin and his buddies go to graduation in Army dress. While the ribbons displayed are hard to identify, several things are sure. They don't have a Washington National Guard ribbon, so they're regulars, and they have no Middle East service ribbons. So just where did they acquire so much fruit salad?
Continuity mistake: Approximately 10 minutes into the movie the main character is going to burglarize a house and there is a guard dog on a chain in the yard that bites him, through a black mask, on his left cheek. After he is in the upstairs bedroom trying to open a safe, you can see blood around the hole near his left eye, but when he pulls off the mask, there is no longer blood on his left cheek, or any signs of a puncture wound.
Other mistake: When Lisa and Toby are out, they are drinking Beck's Blue, a non-alcoholic version of Beck's, yet they still appear to be drunk. (00:39:30)
Revealing mistake: After the 4 have been tied up and babyface has killed their captors, he grabs Alexa by the neck. There is a shot of him from behind and you can see the make up covering the back of his head/neck coming up above his collar.
Continuity mistake: When Mary first opens the phone book at the post office she lands on Finklestein but when she puts her finger on the name she chooses it as Hororwitz, even though she never turned the page again.
Factual error: When the Lincoln Continental Convertible was rolling backwards down the hill, Nick put his hands on the trunk to try to stop it. A car, especially one weighing 5,000 - 6,000 #, would easily knock over a person and possibly cause serious bodily injury (even death). Nick's attempt to stop the car by holding onto the driver's door handle would also be futile and potentially dangerous. (00:37:47)
Continuity mistake: When Max is going to stab Naoko at the end of the movie, he grabs her by the hair, but in the next shot he's grabbing her by the chin. (01:18:30)
Continuity mistake: In part 2, as it shows the police cleaning up the crime scene from the end of The Final Chapter, they are shown picking up Jason's hockey mask to place it in an evidence bag. However the cut in the top of the mask from where he was hit with an axe in the previous film is missing. (00:01:05)
Continuity mistake: During the scene when Ian is taped to the chair, the duct tape across his shoulders changes from shot to shot. Some times it touches the shoulder seams on his shirt, and other times it is several inches away.
Continuity mistake: When Joel and Dean sit at the booth to talk, Dean places two beers on the table such that the labels are facing the camera. As they talk and the camera switches back and forth between the two friends, Dean's beer switches orientation showing the label in some shots and not in others, despite the fact that he does not touch the bottle whatsoever. There isn't enough time between shots to allow him to move the bottle or drink any as the bottle remains full.
Continuity mistake: During the fight, the extent to which the fire (starts on top of the mound) spreads toward the ground varies. Also, the fire burns downward through snow, but does not melt the surrounding snow along the sides and bottom of the mound. (01:15:35)
Continuity mistake: Sophie Marceau's Jeanne meets the Hachette executive Robert (Didier Flamand). She enters the room with handbag and jacket in one hand. She then follows him into the other half of the room. Now she has her clothes in her right hand and her bag is in her left. Not just that; the man had the folder in his left hand in the first shot, but in the new one it's in his right. (00:04:25)
Continuity mistake: After the spittoon cup gets spilled on Samir's shirt, the stain changes and becomes smaller in a later shot.
