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)
Continuity mistake: When Cole fills the water jug at the creek, it is only about a fourth full of water when he caps it and hands it to Captain Burroughs. A moment later as they are walking away, the jug is almost completely full of water. (00:18:50)
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: 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)
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.
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.
Continuity mistake: When Pippa and Herb are having dinner, she hits the table with her fist and wine splatters on his shirt. When he stands up and walks to the bedroom the shirt is spotless.
Revealing mistake: In the evil woman's dramatic scene after she kills the children, her knife flops around like it is made of rubber, but sounds solid when she throws it in the sink. (01:22:35)
Character mistake: At the hospital, the inspector manages to get from the nurse the file of the patient with the liver condition. Forgetting the fact that the Turin, Italy hospital is using English for its documents (it's simply a cinematic convention), the problem is that the letterhead of this document says "Department of Chronic Deseases", misspelling the word.
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: Mulan tricks her father into taking his medicine, and everyone has a laugh at him. Between shots she is pouring from the teapot first with the right, then the left, and one of the geezers sitting by is cackling with a different posture and hands switched as well. (00:05:10)
Revealing mistake: When the girl is giving the guy a blow job in the school restroom, he finishes in her mouth. She goes to the sink and spits it out. You can obviously tell she had a mouthful of water going by the color and quantity. (00:20:45)
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)
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)
Plot hole: In the series we learn that these creatures take a lot longer than us humans to grow up and that they live a lot longer. They mention that the children are about 900 years old, so a grown-up would be more than 1000 (probably 2000). The series is set around our time (1990s/2000s) and Fjellrose and Erke are very old. Yet the film is set about 100 or 200 years ago, you can tell by the way the humans are dressed and the way their houses are built etc. So Fjellrose and Erke should still be grown up, but they are young children. If they are only 100 to 200 years younger, then they should be much older in the film or much younger in the series.
Continuity mistake: The young 'au pair' does not have what it takes and resigns after falling into the fountain. As she speaks with the Caldwells, her wet hair is in front of her shoulders in a shot, in the reverse shot it is not, and so on. (00:04:20)
Continuity mistake: When the family is in a parking lot, the amount of beer in the glass on the car's rooftop keeps changing between shots.
