X-Men Origins: Wolverine (2009) - 12 mistakes

Deliberate "mistake": After Wolverine arrives at 3 Mile Island he approaches through a thick fog. Above him are a series of conveyor belts that are used at a coal power plant, not a nuclear plant such as 3 Mile Island. The belts are unique to coal mines and coal power plants, and would not be found at a nuclear power plant. The filmmakers obviously couldn't film on the site of a nuclear plant, so filmed on a coal plant to fill in.

Revealing: When Logan is at the old couples' house and checking out his new claws in the bathroom, watch where they come out of his hand carefully - the animation of his CG claws doesn't totally replicate the movement of his hands, making it look as though they are floating around his knuckles.

Continuity: When Logan stops Victor from killing someone at the camp in Africa, he is holding his wrist. When he is looking at Victor with his back towards camera, you can see his claws out. However, when it shows him face on, they are gone.

Revealing: When the old couple who give Wolverine clothes are first driving towards their house, there is an aerial shot of them driving over a bridge. This is supposed to be set in Canada (drive on the right) but it was filmed in New Zealand (drive on the left). They are driving on the right but the arrow on the road is on the left side.

Continuity: Wolverine fights the Blob in the boxing ring and knocks him out. When he interrogates the Blob on the whereabouts of 'the island' he draws his claws in a horizontal line, but when the shot switches back (beside Wolverine's shoulder), his claws are in a vertical line facing the Blob's face. The alignment of the claws switched from horizontal to vertical every time the shot changes.

Continuity: When Wolverine wakes out on Silver Fox , Stryker and Sabretooth at the nuclear plant, he is wearing his white undershirt with a red button-down shirt over it with the sleeves rolled up. A second later he hears Silver Fox scream and he rushes back in, but the red shirt is gone.

Continuity: When Logan chops down the tree, its canopy is shown to be rounded, but when the tree hits the ground it has a different shape, noticeably more pointed at the top.

Continuity: When "New" Wolverine breaks out of the dam, after he was soaked in water, he comes out perfectly dry and hair neatly styled.

Revealing: When the team of Mutants are in the small village in Africa, it all goes kinda crazy and there is a bolt of lightning. If you look at the back left corner, you can see one of the flashes from a light they use to create the lightning flash.

Factual error: After Logan and Victor are busted in Vietnam, we move to "6 years later" and we experience the rest of the film. The Vietnam war ended April 30th, 1975, which means that the latest that this film could have taken place was 1981. In addition, The Three Mile Island accident occured in 1979. However, the Army in the film is regularly using Humvees, which did not enter into production until 1984.

Continuity: In X-Men 2, when Wolverine re-enters the room where he had the adamantium grafted to his body, there are numerous claw marks on the walls and water bath which have obviously been made by him (3 marks, ie. his claws - Deathstrike would have made 4 or 5). In this film he just gets up and runs out of the room, doing nothing to justify where the claw marks come from.

Other: After Wade stabs the last two gunmen he turns to say the line, "OK people are dead", and you can see the sword is clean, no blood.
