In the last shot inside Magneto's plastic prison, when Xavier says, "And I will always be there," the guard's visible shirt pocket has a metal button. [There is no way to say with certainty that the button is metal, so it must be assumed that it is plastic.] Corrected by Phixius

When Sabretooth is at the train station, Storm looks around and he begins to lift her up, yet when the shot goes to her feet we see the back of her legs just turning around and lifting up. (Storm may have great powers but I doubt she's a contortionist). [Watch the movie again. When Sabretooth comes up behind Storm, she only turns the upper half of her body partway around, and then when Sabretooth grabs her and lifts her up, he turns her the rest of the way around so she is facing him completely.]

Near the start of the film when Sabretooth comes back without the mutant, Magneto asks, "What happened?" Just after this, when he pulls out the chair, if you watch closely he moves his hand up twice, and the chair moves out twice (slo-mo required). [Requiring the viewer to "watch closely" and to use "slow motion" for a minor repetitive action invalidates mistakes such as this. As it states on the 'Contributions' page, "If something requires slow motion to spot, chances are it's not a valid mistake...but a tiny change in position...that's only noticeable by slowing the shot down won't be listed."] Corrected by Rikki

When Wolverine and Mystique are fighting, Wolverine cuts off Mystique's knives, because she is in Wolverine's form. If he cut off her knives, wouldn't that be like cutting off her fingers or something? They are still part of her body. [Yes, that's exactly what he's done, which is why she cries out when he does it. It's not her fingers, but it's definitely some body mass. Not a mistake though.] Corrected by Tailkinker

When in the Statue of Liberty, Magneto magnetizes the bars to keep Wolverines hands pointed at himself and hang him against the wall. Wolverine decides to stab himself, which makes him fall. Maybe I'm wrong, but why would stabbing himself make the magnetism wear off so he can fall? [Magneto doesn't magnetise the bars to keep Wolverine imprisoned, he simply uses his powers to bend those bars into shape. Once he stops bending them, he has no further effect on them and they're just metal restraints. When Logan pops his claws through his own body, he severs the restraints at the point where they join the wall behind him, allowing him to get loose.] Corrected by Tailkinker

At the beginning of the film when the owner of the bar is holding a shotgun to Wolverine's head, if you look at it closely, the shotgun turns from black to silver between shots. [I've viewed this scene countless times. The shotgun NEVER changes colour. The lighting reflecting off the shotgun changes slightly but the shotgun is always black.]

It is established that the X-Men's base of operation including Cerebro are in underground levels. In this scene, you see Bobby walking with two friends talking about Rogue missing. Mystique (as Bobby also) walks out of the round elevator as the real Bobby walks past. They are on the main ground floor. The next shot, Mystique as Bobby is in the underground level standing in front of the door to Cerebro. Why is she in the elevator in the first place that she'd exit on the ground level, and why would she exit at the ground level if she just has to go back in to go down to the basement to access Cerebro? [She may have come from upstairs, not shown in this film, but in X-Men 2, it is shown that the elevators also go up to the 1st floor, as Bobby uses it to go upstairs to find Rogue.]

After Senator Kelly's death, watch Storm as she runs away. On her right, a microphone wire is visible. [Doesn't appear to be a wire, but rather a line in the fabric of the shirt she is wearing. There is one on the other side that you can see when she walks in to the room. Also, I don't think they wear microphones. Usually there is a boom mic overhead. You can see examples of the boom being used in the special features disc of X-Men 1.5 that shows you behind the scenes footage.]

The "copper" straps used to restrain the heroes in the Statue of Liberty are actually made of foam or some other malleable material. They flex considerably as the characters struggle. [If you read the movie novel, you find that Jean was trying to tear the straps away with her telekinesis. No one mentioned it in the movie.]

When you see the X-ray of Logan's body, you see the solid metal blades that shoot out of his hands. In the X-ray, they go from just before his elbow, up his wrist to the middle of his hand. But later Logan bends his wrist. How does he do that if the blades don't bend? [The blades could retract slightly to allow his wrist to bend. After all, his blades come out on command so who says he can't make them go back when he needs to bend his wrist. Or it may be that he was slightly nervous when the X-ray was taken so that he blades are actually already slightly extended from their normal position.]

Near the end, Cyclops tells Storm to "fry" Magneto. Magneto then answers, "..lightning bolt in a small copper space..." meaning that everyone would be "fried". This is total baloney, as the bolt would hit Magneto directly, then discharge into the floor of the statue and dissipate in energy through the whole statue. Magneto would receive a direct hit and as the main conductor and would be instantly killed. The others would also be shocked, but to a substantially lesser degree and certainly not life-threatening. However, Magneto seems to either not know this, or more likely is lying with the (correct) assumption that the others don't know that either. [You are assuming that Storm would be able to pinpoint a bolt of lightning through the small hole in the statue and into Magneto. It is more likely that the bolt would come near the statue and be attracted to the metal as it neared the hole, causing it to veer off and spread through the walls (where the X-men were chained).] Corrected by Twotall

Right after Wolverine has stabbed and Rogue has absorbed his power, she turns around to face Storm. The front of her nightgown has no holes from the stab. [This was already corrected, but here it is again. Look closer, or at a still from the scene. Rogue's top did not have material over the front of her shoulder to begin with, so there was nothing to puncture. Her hair is in the way so you can't see the blood or torn flesh in the front.]

In the train station scene, when Magneto, Beast, and Toad go outside, Toad has Cyclops visor on his head. Later on in the movie Cyclops is wearing the visor. [That was Sabertooth. Not Beast. Also, one would think that Cyclops has more than one visor in case he loses one while fighting.] Corrected by Maria Santos

In the cage fight with Logan and the trucker guy, Logan takes 2 in the face, and 2 in the stomach, the 2 in the face should have hurt a whole lot considering Logans face is laced with Adamantium (later shown when Logan knocks the guy out with his chin and a metal sound is heard) [I don't think that your nerves can appreciate any difference in hardness due to being crushed against adamantium coated bones as opposed to plain bones - they are just as hard compared to flesh. It's like saying falling out of a plane onto concrete would hurt more than falling out of a plane onto tarmac.]

Why isn't Magneto wearing his protective helmet on the boat towards the end of the film? He has no way of knowing that Mystique's sabotage of Cerebro worked - for all he knew, Xavier could have been tracking him at that moment. [Mystique can't make a phone call?]

Xavier might not want to kill Magneto outside the train station, but he could easily have used Sabertooth to knock his protective helmet off or slam him into a wall and knock him unconscious. If he had done this immediately (before Magneto pointed everyone's guns back at them, after which it was obviously too risky) he could have captured Magneto then and there. Granted, not very good for the film, but it still should have occurred to him. [Ignoring the fact that Professor X and Magneto are very old friends, it's very clear throughout the movies and comics that Professor X does not want to get into a physical conflict with Magneto - instead, he wants Magneto to convert to the ideology of the X-Men. This is important because attacking Magneto will only escalate the conflict, whereas converting him would also bring many if not all of his followers. In addition, Professor X is in Sabretooth's mind - Sabretooth knows that the helmet fits Magneto very tightly (hard to knock off) and protects him from physical violence as well as mental intrusions (hard to knock out).]

When Wolverine is in the bar right after his fight listen to what is said on the TV. The guy is saying that "over 200 nations' leaders will be present" and he is referring to the meeting on the island. There are only 191 nations recognized by the UN. So how could their be over 200? [The film is set in the near future - by which time there may be more recognized nations than there are at present.] Corrected by Chimera

Just before the tree crashes down on Logan's truck, Hugh Jackman says the line about driving safety in his natural, Australian accent. [As an Australian, I don't believe what he said was in an "actual" Australian accent.]

The helicopter markings and paint schemes are exclusive ONLY to POTUS (President of the United States). Senator Kelly, even thought he's trying to get a Presidential bid, wouldn't be allowed to fly around in aircraft marked like that. [This film is set in "The Not-Too-Distant Future". The helicopter markings etc may have become exclusive to POTUS and senators by that time. Unlikely, maybe, but definitely possible. ]

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. [I've watched this scene from beginning to end very closely and can see that the cigar never disappears in any shot. Whenever he puts his hand on the steering wheel the cigar stays in between the tips of his fingers.]
