Corrected entry: In the scene where Magneto's Brotherhood attacks, research lab soldiers use plastic weapons to prevent Magneto controlling them. However, even if the weapons are made of plastic, needles on syrettes are made of metal, so he should be able to feel and control them.
Corrected entry: When they first attack the bridge and everyone is escaping from their cars and jumping off the bridge, none of the cars have their lights on. Yet after darkness suddenly falls (see the other mistake), all the lights on the cars on the bridge are all on, despite no-one being left in their cars to have turned them on.
Correction: When we first see the bridge before the attack, almost all the cars have their lights on.
Corrected entry: In the scene where Jean and Magneto are overlooking the camp of mutants, Magneto talks to Jean about her powers. He holds up the weapon with the antidote and says he can only control metal then levitates the weapon. The weapon was supposed to be made of plastic as revealed later in the movie. The alternate scene shows him levitating a metal mug instead which made sense with his line.
Corrected entry: When Shadowkat meets Leech in the complex, she can't phase through the wall to escape because being near Leech negates her mutant powers. When Juggernaut enters the same room, he is unable to break through the wall for the same reason, however Juggernaut technically isn't a mutant, his abilities were received through mysticism so his powers shouldn't have been affected.
Correction: Inapplicable comic book mistake. In the movie, Juggernaut IS a mutant.
Corrected entry: Juggernaut's power is the ability to gain great strength but only by building momentum. This was proved when the loss of momentum, by locking his arms and legs down in the mobile prison, is how they were able to contain him. However, when Kitty Pryde sinks him in the floor, he bursts out effortlessly, despite having his arms and legs fully pinned down in concrete and unable to gain momentum.
Correction: Even though Juggernaut is not a mutant in the comic that is not how his power works. Juggernaut has uncharted superhuman strength like the Hulk and could have easily broken through the floor like he did. When he was in the back of the truck the point they were trying to get across was that he is so strong that nothing can stop him short of fully restraining him as so he can not move or even wriggle.
Corrected entry: When we see Magneto move the Golden Gate Bridge to Alcatraz he sets it down so that there is a bridge across the mainland to Alcatraz. The bridge is supported only by the island and the mainland, this wouldn't happen as a bridge that long and heavy would just collapse in the middle, that is why suspension bridges with supports in the middle are needed.
Correction: Already listed. See minor mistakes.
Corrected entry: Somehow, Angel manages to get from New York to San Francisco, just in time to save his father. Of course, this takes place about half an hour after the other X-Men arrive in a super sonic jet. Even with some feathery wings, that's quite a distance in such a short time.
Corrected entry: When the troops start mobilising to attack the Brotherhood, they make a big show of removing 'all metal' from their gear. However, multiple times the soldiers are shown using radio equipment built into their helmets. Even if they replaced everything they could with plastic, electronic impulses still require metallic wire to operate, and since in X2 Magneto made good use of iron injected into someone's bloodstream, a decent collection of wires would definitely have been enough for him to use to kill the troops.
Correction: There are semi conductors other than metal. There are silicon conductors and organic conductors that are in use already and more being researched as I type this (Read ACS or Scientific American Journals). Therefore, it is entirely possible that the "wiring" in the radios and helmets was created out of this non-metal, semi-conducting material.
Actually Magneto is able to control and manipulate the magnetic fields, not "metals" as such. Since every electric charge in movement generates a magnetic field the user has made a good point. Probably that level of control would had left him exhausted and vulnerable though.
Corrected entry: In the scene where Juggernaut is attempting to catch Kitty Pride and Leech, he runs and ends up hitting his head on the wall and knocking himself unconscious (due to the fact that Leech has the ability to nullify other mutants' powers). However, Juggernaut is not actually a mutant, as his power is derived from the suit he wears (an alien suit). Therefore, in reality he would have still bashed through the wall and Leech's power would have had no effect on him at all.
Correction: Incorrect. In the film, Juggernaut is a mutant and thus Leech can affect him. The fact that his origin is different in the comics (it's nothing like what you suggest, by the way) is irrelevant.
Corrected entry: When Magneto is holding Wolverine up in the air in the forest you can plainly see one of the wires used to hold him up.
Correction: Watching this now, I see nothing. This scene is loaded with trees and branches, and there are no wires in plain sight as suggested.
Correction: This could have been fixed two ways: 1. They could have used a non-magnetic metal (such as aluminum or stainless steel) to make the syringes; or 2. They could have used a plastic needle (which does exist). Even if they didn't exist in real life; it's safe to assume that they could have developed one in the X-Men universe since it takes place a few years in the future and they have shown technology that is more advanced than what we currently have. Besides; when was the last time you saw a "plastic" firearm, outside of some hijacker's fantasy?
