Corrected entry: In this movie, Emma Frost is seen as an adult woman [roughly around the same age as Professor X and Magneto]. But the character is also in X-Men Origins: Wolverine, set years later when Professor X and Magneto are much older, but in that movie she's younger than she is in this one.
Correction: The Emma in First Class and the Emma in Origins: Wolverine are two different people - Emma (First Class) is Emma Frost, White Queen, telepath a with secondary mutation rendering her skin like diamond. Emma (Origins: Wolverine) is Kayla Silverfox's sister, unknown mutant, but also has a mutation rendering her skin like diamond... Just because they have the same mutation, and coincidentally the same name, does not make them the same person.
Corrected entry: In the beginning of the film, Shaw gives young Erik a coin. This coin is a 5 mark Nazi coin dated 1934, yet the coin was only produced from 1936-1939.
Correction: The coins were produced from 1934 - 1939.
Corrected entry: When Erik is destroying Shaw's yacht with its own anchor, in the shots of the chain slicing the top half of the boat, the chain exerts a forward force on the yacht, but the boat is stationary. This is impossible considering it is floating in water and the slightest nudge would make the yacht move.
Correction: The yacht has a lot of mass and therefore a lot of stationary inertia. The water also creates a significant amount of resistance against the hull. As long as the amount of energy needed for the chain to slice through the yacht is less than the amount of energy needed to move the yacht, the yacht would remain stationary during the attack. Especially if Erik is holding the yacht still with his powers in order to make his attack more effective. If you think "the slightest nudge" is all that's required to make a boat that size glide through the water, I invite you to visit your nearest marina and just try shoving a few boats around.
Corrected entry: When Raven is making a pass at Erik in his bedroom he brushes her off by saying that she would need to be a little older. She then makes herself look older - this older woman is Rebecca Romijn, who played Mystique in the original 3 X-Men films.
Correction: This is far too obvious to be trivia. It is an attempt by the filmmakers to tie this film in with the previous films, not trivia.
Corrected entry: In the movie when Xavier is using CEREBRO for the first time keep an eye out and you can briefly see young versions of Storm (girl with white hair) and Cyclops (boy with soccer ball and dark sunglasses).
Correction: Not likely. The film is set in 1962. If those characters were intended to be Storm and Cyclops, they would be in their mid-40s in 2000, which is when the first X-men film was set. More likely is that they were simply generic mutant children.
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 nueral connections at the site of the spine injury, and, are well documented in the medical and diagnostic literature.
Corrected entry: In the credits James McAvoy is listed as Charles Xavier (Age 24), then Xavier is listed as Age 12 with Raven at Age 10. If Charles and Raven first meet in 1944 at the ages of 12 and 10; then in 1962, 18 years later, Charles would have to be at least 30 years old - not 24. Raven would then be 28 and not a teenager as she is portrayed.
Correction: Xavier's age notwithstanding, it is stated in the film that Mystique's mutation causes her to age slower than a regular person, so her appearing to be younger than she actually is is entirely consistent with what is said about her powers.
Corrected entry: When Magneto lifts the submarine, he is the point from which the submarine hangs. But Magneto is hanging from the jet, so basically, that is carrying the submarine. And there is no way a jet, even one that powerful, can lift a submarine in mid-air.
Correction: You're misunderstanding how Magneto's power works. If his body were the anchor, he would not be able to ride pieces of metal that he levitates; that would be like trying to pick yourself up by your belt loops. It's his power alone, not his body, that supports the objects he manipulates.
Corrected entry: When Banshee is showing off his power in one shot of the movie he destroys the window. In the other scene at the CIA center two of the guards are picking on Beast and he closes the blinds at the window.
Correction: The window was undoubtedly replaced promptly. That's a pretty big hole to just leave in the side of your top secret government facility after all.
Corrected entry: Emma Frost can turn into diamond, which is the hardest material in the world, yet the Erik is able to use the bedpost, most likely made out of a soft metal, to both strangle and starting to crack her neck.
Correction: You're confusing "hardness" and "toughness", I'm afraid. Diamond may be the hardest material on Earth, but it's not actually that tough, in fact it's extremely brittle. If you wanted to scratch diamond, true, metal would be pretty much useless, as it's not hard enough, but if all you wanted to do is break a diamond, a good whack with a hammer will do the trick. A piece of metal, particularly one backed up by Magneto's powerful ability to manipulate such objects, would be readily able to apply enough pressure to make a few cracks.
Corrected entry: In the scene where Erik is in the bar in Argentina, after the fight starts the bartender says "Oye, cabron". From his accent it's obvious that he's supposed to be a native Argentinian, but the word "cabron" is never used in the Argentinian dialect - it's mostly used in Mexico and Spain.
Correction: This doesn't mean a person in Argentina cannot use that word. I know some American people that like to say "scheisse" even though it is a German word.
Corrected entry: Moira McTaggert, who has NO mutant powers to prevent her aging, is shown to be in her 30s in this movie set in the 60s. The X-Trilogy is set in the 2000s according to the novelization. That's a gap of 50 years, so Moira should be in her 70s in the trilogy. Yet, when we see her in X-Men 3, she's barely pushing 40.
Correction: First, she's never stated to be in her 30's in First Class. She could very well be in her 20's. Second, she's never stated to be in her 40's in X3, she could be much older, having merely aged gracefully. Finally, the novelization is not movie canon. It's a separate medium.
Corrected entry: When trying to teach Banshee to fly, he is told to make his sound waves super sonic. Sound waves cannot be super sonic. Sound can only travel at the speed of sound, it always does. I guess they were trying to tell him to use a very high frequency, but the speed would still be the speed of sound.
Correction: From Dictionary.com: Supersonic - "of or having to do with sound waves beyond the limit of human hearing".
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?
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.
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: During the scene with the SR-71 Blackbird, while Erik is on the wheel assembly, Professor X yells 'Hank tank my hand' several times. Hank is flying the plane. Erik is the one he is trying to save from falling.
Correction: He says Erik. Xavier's accent and the noise surrounding the scene just make it sound like he is saying Hank.
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.
Correction: Erik meant that he would kill her if she changed into her diamond form again. The cracks in her neck not reappearing imply that her diamond form can regenerate itself.
Corrected entry: In the end of X-Men: First Class, Magneto puts on his helmet to protect himself from Xavier reading his thoughts. In X-Men: The Last Stand, the pair go to visit Jean as a child and Magneto is not wearing a helmet, even though the setting is much later.
Correction: Apparently, they patched up their differences in the time in between the two scenes (as they have done, several times, in the comic books). Magneto would not necessarily feel the need to shield himself from Xavier when they are working together. In addition, it would attract all kinds of unwanted attention to walk around with that helmet on.
Corrected entry: Xavier and Magneto attempt to recruit Wolverine but, in the first X-Men movie Xavier has no prior knowledge of Wolverine, despite the fact that it is in the future.
Correction: Xavier apparently knew of Wolverine in the first X-Men movie but chose not to say anything about their meeting in 1962. He knows that Wolverine is very distrustful of anyone from the time before he lost his memory; telling Logan that they had met sometime in the past would only raise suspicions.
Corrected entry: The scene at the beginning is set at a German concentration camp in occupied Poland in 1944 (as annotated). Scientist Sebastian Shaw, who has observed Erik bending the metal gate through a window, calls the boy up to see him. On entering Shaw's office, the song "Non, je ne regrette rien" is playing. The song was written in 1956 and recorded by Edith Piaf in 1960.
Correction: The song playing in the doctor's office is actually "La Vie En Rose." This song wasn't popularized until 1946, so it's doubtful it would have been playing at that moment.
