Revealing mistake: When Solina is crawling on the wall, whenever she turns her head, her long hair turns with it, instead of falling freely downward toward the floor. (01:05:20)
Revealing mistake: In the scene where Rudolph is saving Tony from the truck he says, "close your eyes, Tony". But in the next scene when they are on the blimp the boys introduce themselves. Rudolph did not yet know Tony's name but yet he said it.
Revealing mistake: You can see the plane intact even though it has exploded. It stays complete, there's just fire around it. (00:18:55)
Revealing mistake: Jennifer swipes her card the wrong way at the studio and the door opens anyway. (00:57:15)
Revealing mistake: Many times throughout the movie, people are shot and they bleed, but their clothes don't have holes from where the bullets hit them. The most noticeable examples are when the teacher is shot at the end, and when the big gun fight between the girls breaks out in the lighthouse.
Revealing mistake: Near the end when a naked John Jasper kills M, he staggers back and you can see a modesty pouch that is covering his private parts. (01:31:47)
Revealing mistake: When the bleached dead girl is lying on the table, you can see her breathing. (00:13:45)
Revealing mistake: When the Abbe du Coulmier comes running around the corner towards Marquis' cell during the fire scene, you can see him smash his head against the wall.
Revealing mistake: The algae in the "garden" is fake. It is cloth.
Revealing mistake: When Nick has swam back to his water scooter, he climbs up and drives away and the shark comes up behind him. But look carefully behind Nick as he is climbing. The nose of the shark is visible during the whole scene, right under the surface. This proves that the shark was a dummy, waiting to come up.
Revealing mistake: In the fight scene between Riddick and Johns, there is a wide shot of them both fighting over Johns' shotgun. In this shot it is apparent that it is not Vin Diesel in the shot but in fact a stunt double. (01:17:35)
Revealing mistake: Trevor Stark appears as the twin brother of Travis. They both have the same scar on their left cheek. Therefore they are the same person and not twins.
Revealing mistake: In an early shot shown from the neighbor's house, it is established that the Spencers' house is quite a ways uphill. Some of the later shots where Claire is spying on her neighbors and looking at their home, the angle of view does not appear to be correct. The neighbors' house looks like it's a lot closer and more level with the Spencers' home.
Revealing mistake: In the end, when Paula kills Hein, you can see in close-ups that the scars on his face are on tape and not on his skin.
Revealing mistake: The 7 Children on the road that Kim swerves to avoid and dents the car are obviously wearing facepaint - and it's been applied very badly at that.
Revealing mistake: When Jessica's dead body is seen by Annie in her bath and then in the hall, the make-up that is keeping Jessica's eye shut is coming away around the edges.
Revealing mistake: Sebastian Caine wears a latex mask and latex gloves in order to appear near-human. The mask he wears is fairly long, and covers his neck, and the tops of his shoulders and collarbone. However, there is a scene in which Linda and Matt are helping a nauseous Sebastian reach the toilet, where he vomits (invisible fluid) into it. In this scene, when Sebastian breaks free from them and runs to the toilet, we can see that his arms and chest are also visible, skin-colored. The mask he wears only reaches the very base of his neck, so it is possible that the actor playing the invisible man did not realize that the tops of his arms and chest were visible. (00:49:20)
Revealing mistake: When Patrick opens his fridge to offer Jean some sorbet, you can see the decapitated head of a woman in the fridge. If you pay close attention, you can see the head is moving a little. (00:59:36)
Suggested correction: It's a prop head resting on a freezer shelf. It could simply be that opening the freezer door causes the head to sway a little, similar to if you had an egg, lemon, or something else that didn't have a flat bottom resting on a shelf inside a fridge.
No, the way it was filmed was with the actual actress putting her head up through a hole in shelf. It's her head moving.
Revealing mistake: When Tomie's disembodied head is on the ground, taunting the lead characters, you can easily tell that the actress is just sticking her head through a hole in the ground. She's moving far too much, which gives away the effect.
