Revealing mistake: When Herbie is being pulled from the truck at Crazy Dave's, Herbie goes into reverse and the camera does a closeup shot of one of the rear wheels reversing. If you look carefully, you can see an extra set of small wheels behind the tyre which are obviously propping the car up enough so that the cars proper wheels will only skid and not get any traction.
Revealing mistake: In the game against Liverpool, there is a reversed shot after Harris scores the first goal. It is fairly obvious since all of the players' numbers are backwards, in addition to the advertisements in the background. (01:45:25)
Revealing mistake: When Chelsea is on the roof of the house and Kathy joins her, Kathy's hair is blowing in the wind, while Chelsea's stays perfectly still, the water in the lake is also perfectly still. Obviously the director had the actors do the scenes separately until we see them both together in which case both characters hair is blowing around. (01:27:40 - 02:00:00)
Revealing mistake: There is one shot of the Duke boys in their car talking to Uncle Jessie with the CB radio. You can hear Uncle Jessie respond (through the radio) while Bo/Luke still has the button on the microphone pressed. When the button on the mic is pressed, no sound comes out of a CB radio at all, as they cannot transmit and receive at the same time.
Revealing mistake: When Christina Ricci picks up the silver knife off the floor in her house and her hand starts to smoke, pay attention to the shadow. You can see smoke coming from her wrist before her hand touches the knife.
Revealing mistake: On many occasions throughout the film, Keira Knightley's real, short hair can be seen under her wig.
Revealing mistake: When the talons and E.D.I. attack the fort during their first mission, the explosions show the use of pyrotechnics when A.T.S. missiles explode in a simple blast.
Revealing mistake: When the Mob's FBI is about to storm the house they shoot the transformer cutting power to the house. But yet when Bruce Willis shoots the fountain in the house it is still pumping out water.
Revealing mistake: After Alex steps off the bus at the same corner as Camryn and Beth, some of the same extras keep walking past in quite a few of the following shots. Two examples are the woman wearing a striped top and black skirt, and the man wearing a plaid shirt and tan pants. (00:09:25)
Revealing mistake: When the group finds the picture of Daniel and his father Eric in the house, look closely at the photo - it was obviously very poorly patched together with photoshop. The lighting on Daniel/Eric does not match the lighting in the background at all, and it's clear that they have been crudely "cut out" of another photo and inserted over the background image. The extremely poor, obviously fake quality of the photo is even jokingly mentioned in at least one of the DVD commentaries. (01:01:05)
Revealing mistake: Very obvious stunt double when Dennis Quaid's character falls off the forklift into the kiddie pool at the hardware store.
Revealing mistake: When Ben falls from the roof and into the leaves during the storm, you can see the mat that he lands on move from under the leaves.
Revealing mistake: As Lady Tottington leaves Wallace's home, the ivy between the windows on the left suddenly changes a bit- a portion gets squashed flat (about 2 bricks down and to the left of the house address numbers) as the area gets a bit blurry. The modelers must have not noticed bumping it while working with the doll. (00:57:15)
Revealing mistake: At the beginning of the movie, when the guy is bitten in the wrist, if you watch and listen closely when he shoots himself, the blood comes out of his head before he actually shoots.
Revealing mistake: When they are playing N64 look at the system, there is no game in it.
Revealing mistake: In the shot when Rosario cries in silence with her dead brother at the bed he moves the little finger of his left hand.
Revealing mistake: After Majid commits suicide, he is breathing.
Revealing mistake: When Charles Shine arrives at the bus station in the pouring rain, the background on all sides of him can be seen to be pure sunshine and dry land. It is obvious that a rain machine covering a VERY SMALL area was being used.
Revealing mistake: When Hayden is talking to the Psychiatrist in the Hospital, he is wearing some type of white powder face makeup to make him appear more "ghostly". This makeup was only applied to his face. Whenever they show a side shot of his face and neck during this scene, you can see the demarcation (line) of where the white powder face makeup ends and his natural darker tan neck begins. (01:05:20)
Revealing mistake: When Avner finds Carl dead in the hotel bed, you can see a pulse in Carl's neck.
