Corrected entry: In the scene just before Rogue asks Wolverine if it hurts him when his metal claws come out, Wolverine takes a drag on his cigar which is in his right hand. The camera angle changes and he places his right hand on the steering wheel. If you look closely you can see that his cigar has magically vanished from his hand.
Corrected entry: In the beach scene when senator Kelly is watching the news at the hot dog stand, we can see a big chain behind it; the next shot shows Kelly taking some clothes than were hanging on the chain; those clothes were not there in the previous shot. (00:43:56)
Corrected entry: In the scene after Sabertooth attacks Logan in the car, he (Sabertooth) confronts Magneto. It then shows Magneto sitting down and using his powers to take Logan's necklace from Sabertooth, but when he lifts his arm up, there is no number on it from the concentration camp. When in the very next shot, it shows the number back on his arm.
Corrected entry: In the scene right after Logan hits the hood of the truck, and Sabretooth is distracted by something, you can see Storm's hair is pulled back in a pony tail (you can also see it when she gives Rogue a hand out of the truck). But when they are still standing out in the open, the camera view switches behind them, and her hair is blown forward around her face. Then it is back in a pony tail. (00:20:13)
Corrected entry: When Mystique disguised as Bobby is telling Rogue that the professor is mad at her and to leave (after the Wolverine incident) you can see his breath meaning it was cold, but whenever it's a shot of Rogue, there's no breath. Has it warmed up or something. Some people say it's because he's Iceman, but following that thought, it's actually Mystique.
Corrected entry: When the X-men arrive at the statue of Liberty the police helicopter, which was hovering in the area, has disappeared leaving 200 world leaders without protection from the air. Meanwhile all the commotion is about to start there. Also there are no guards in the statue, which again is odd, because it would be THE spot for a sniper to shoot any of the worldleaders, which for some reason hold their summit in the open air nearby.
Corrected entry: In the scene in the Statue of Liberty where Wolverine shoots his claws through his chest to escape, how does this help? His claws are extremely sharp, as is shown later in the film when he cuts off a part of the statue that is made of solid metal. His claws should simply perforate the metal, instead of helping release him.
Corrected entry: Much is made of Magneto's helmet which stops Professor X using Cerebro to find him. However, he can control Sabretooth and Toad (at the train station) and presumably knew that Sabretooth was about to attack Wolvie and Rogue. So why couldn't he find Magneto's base by tracking one of his followers? Even if the base is shielded, he could still follow them until they disappeared, and it would be pretty simple to work out where the base was after that... (00:55:49)
Corrected entry: When Wolverine is falling down the side of the Statue of Liberty during his fight with Sabertooth (again), and he impales his claws into the side of the structure, they show up on the other side between Jean and Cyclops' faces vertically. However, it looks as though he put them in the structure horizontally when shown from the outside. (01:23:16)
