X-Men Origins: Wolverine (2009) - 14 mistakes

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.

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: 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.

Factual error: When Wolverine leaves one of the compounds, he slashes through the door with both hands, creating an "X" in the door. After the second slice, the portion of the "X" where the cuts actually crisscross remains in the door, when in reality the pieces would fall out as they wouldn't be attached to the door any longer and would be floating in air.

Factual error: During the Vietnam War scene, Logan is seen equipped with what is supposedly an XM177 Carbine/Colt Commando. Unfortunately it's not that weapon, but an M4 which was issued in 1994.

Continuity: When Agent Zero starts shooting while in Africa, he throws his pistols into the air and the slides are open, but just before he catches them the slides are closed.

Factual error: None of the vehicles in the logging camp, purportedly in the Canadian Rockies, have correct licence plates for either Alberta or British Columbia, the provinces the Rockies are located. They are not the white on blue that British Columbia was using in the early to mid 1980s, nor the black on yellow of Alberta during the same time period. They aren't even the red on white for Alberta or blue on white for BC that are currently used since the late 80s/early 90s.

Continuity: In the scene where Kayla is dead and Logan walks to her, her mouth is open in one shot, but in the next shot when his hand is reaching for her eyes, her mouth is closed.

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.

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 Logan takes out the helicopter carrying Zero, as it crashes and rolls you can see a pair of legs coming out of the window. As the helicopter rolls, the body almost entirely comes out, though when Logan gets up close, the pilot is slumped in his seat, with his limbs protruding only slightly from the wreckage.

Continuity: When Wolverine has been catapulted from the truck, Wolverine looks to the right as if to slash the helicopter blades on the right side. Viewing from above the chopper the blades are spinning counter clockwise initially. Once Wolverine reaches the chopper blades, the blades are spinning clockwise, enabling him to slice and dice.

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.
