Corrected entry: Charles says when they are looking at the suits, that they have to wear them because they haven't mutated to endure g-force or being riddled by bullets. Yet somehow a deflected Walther PPK bullet, which is one of the smallest calibers out there, can go through the suit and still have enough power to paralyze Charles?
Corrected entry: In the scene in which Banshee jumps out of the Blackbird, the wings that Beast designed for him aren't on while he's still on the Blackbird, but they appear as he's gliding over the ocean. They're gone again once he's underwater and makes his sonic blast.
Correction: The wings of this wingsuit extend and retract via some unexplained mechanism from a harness strapped to his torso. The straps on his suit are visible at all times, whether his wings are visible or not, and they don't appear on anyone else's suit. Just like no one else has the disc on their chest that Havok has.
Corrected entry: In the scene in the Russian diplomat's bedroom, Erik tightens the bar around Emma's neck so hard that it cracks her diamond neck. Erik says that she can't become diamond again without dying. At the end of the movie, she shifts into diamond form and the cracks in her neck are gone.
Corrected entry: Emma Frost's power besides telepathy is also to change to a diamond-like form, however this applies only to her, not her clothes, and all throughout the movie everytime she changes to her diamond form she appears to be naked, when she should look as a diamond but dressed.
Correction: At no point in the film is it established that this power does not effect her clothes. There's no mistake here, deliberate or otherwise.
Corrected entry: Alex Summers, AKA Havok, is the younger brother of Scott Summers [Cyclops] and is a teenager in the film. Yet in the 90s, when the first X-men was set, Scott was still a teenager when the Cuban missile crisis occurred in 1962, so 30 years between events.
Correction: Scott and Alex are brothers in the comics yes, but it is never explicitly stated that they are supposed to be brothers in the movies. They have the same last name, but no further details are given, therefore, no mistake.
It is stated 2 movies later in X-Men: Apocalypse that Scott and Alex are indeed brothers.
Corrected entry: Near the end, on the island, Mystique changes into Shaw to command his peons not to attack her friends. She is wearing the correct outfit, despite having never seen Shaw dressed like this before.
Correction: Incorrect. She has changed into him wearing the outfit he had when she met him at the CIA base. The outfit with the red blouse and tie, not the one with all the buttons.
Corrected entry: After Prof. X has been shot and is in Moira's arms, he moves his own leg in the background of Erik's recruiting speech.
Correction: With a spinal injury or severing of the spine, involuntary leg movements may occur following the injury and for some length of time. They run the gambit of movements from a slight intermittent twitch to actual leg bending at the knee and hip. These involuntary movements are beyond the person's actual control and have to do with the spontaneous firing of the neural connections at the site of the spine injury, and, are well documented in the medical and diagnostic literature.
Corrected entry: In First Class, Professor X is made handicapped in 1962 at the end of the movie. In the previous X-men movie, he was walking when he visited the girl (Jean) in the mid 70s with Magneto.
Correction: In the next sequel, "Days of Future Past", it is established that there is at least one method by which Charles Xavier can temporarily regain his ability to walk to short periods of time. It is very possible that he was using one of these methods while visiting the young Jean.
Correction: It was also stated that Xavier cannot use his telepathic powers when using the serum, but does when they are talking to Jean. He catches her reading his and even Magneto's mind and especially the latter wasn't just a wild guess. It is very unlikely that he used the serum at this point in time since he has turned his back on it after the events shown in DoFP.
In Days of Future Past, it is never explicitly stated the serum stops Xavier's powers, instead, McCoy explains after Logan questions the actions of the professor that he "designed a serum to treat his spine" derived from his designed to control his 'Beast'. He goes on to say Charles takes "too much." It is possible that after Days of Future Past, Xavier could have pulled back a little, taking just enough to help him walk but not block his mutation.
"The Last Stand" takes place in a different timeline than "Days of Future Past" though. It's possible that in the original timeline, Xavier later used an improved serum that granted him the ability to walk while still retaining his powers, but then stopped using eventually due to it becoming ineffective, harmful to his body or out of concerns of becoming addicted to it.
Correction: The suits certainly are not all over bullet proof, and Magneto may very well have sped the bullet on its way, rather than merely deflecting it, giving it more oomph. The bullet didn't kill him at any rate, so I'd say the suit did its job.
