History ContinuitySnarl / XMenFirstClass

* Regarding the Cerebro montage, Cyclops is a teenager in ''Film/XMenOriginsWolverine'' (set in '79). Creator/JamesMarsden was born in '73 and in his late 20s filming the first two movies, but, if one does the math, he was [[UnderageCasting actually playing a forty-year-old]]. Ditto for the girl made to resemble Storm, who looks like she's a teenager in this film.

* Emma Frost has a fairly significant role in ''Film/XMenOriginsWolverine'' as a teenager, is now an adult a good thirty years earlier, in a completely different role, with additional powers, and playing for the opposite side. Xavier makes no comment about the resemblance when he sees her in ''X-Men Origins: Wolverine''. [[note]]Emma in ''Origins'' was later retconned by the time of ''First Class''' via WordOfGod to be a separate character with some similar powers (not that a Blu-ray extra telling the story of each character didn't do the very questionable decision of trying to say both are the same person). It’s likely Xavier, once he saw her powers, made note of a resemblance, but similar powers in different mutants is not unheard of.[[/note]]

* Regarding the Cerebro montage, Cyclops is a teenager in ''Film/XMenOriginsWolverine'' and in his late 30s/early 40s in the original trilogy, which, if one does the math, would put him at infancy or at most, toddler age in the early 1960s, not the pre-teen (with an approximately 20 years old brother) we see playing ball. Ditto for the girl made to resemble Storm, who looks like she's a teenager in this film.
* Charles and Erik briefly have a run-in with Wolverine, despite the original movie seeming to depict them meeting him for the very first time in the 2000's. Wolverine not remembering them is explained away by his memory loss at the end of ''Film/XMenOriginsWolverine'' but it still creates the question of why neither Charles nor Magneto remember ''him'' or explain that they've met before. However, they only met for about five seconds, and they didn't even look him directly in the eye, so after over thirty years it makes sense they would have trouble remembering him. And even in ''[[Film/XMenDaysOfFuturePast Days of Future Past]]'', it took a while for Xavier to remember him.

* Creator/MatthewVaughn, director of the movie, stated he tried to fit with only the trilogy instead of ''Film/XMenOriginsWolverine''. Too bad Fox and the makers of said movie's Blu-Ray didn't listen, and the Cerebro bonus feature profiling most mutants try to put all 5 films in the same timeline (as mentioned above, [[http://media.comicbookmovie.com/images/users/uploads/35849/2011-09-08_2335.png Emma Frost]] is the most senseless).

* In the original trilogy, Xavier mentions that Scott, Jean, and Storm were his first students. According to this film, ''DaysOfFuturePast'', and ''Apocalypse'', the three of them don't show up for decades after Xavier opens the school.

* During TheStinger, Erik rescues Emma Frost from CIA Headquarters, wearing a distinctive red outfit and red-tinted, horned helmet reminiscent of his classic comic incarnation. While it's not out of the realm of possibility that he may have created more than one helmet, the distinctive silver helmet he wears through the entirety of the film is what he later chooses to wear for decades afterwards, right up until he is caught prior to the flashback scenes in ''Days of Future Past'', and then subsequently through the events of ''Apocalypse'' and ''Dark Phoenix'', while the red helmet he sports in TheStinger of this film is never seen again. It is also decidedly ''not'' the same helmet seen in ''[=X1=]'', which is more rounded and doesn't have any horns.

* In ''Film/XMen1'', Professor X claims he and Magneto first met when the former was 17. This film has their first meeting in 1962, but prior to this shows a younger Charles Xavier aged around eleven alive and well in 1944.

* Hank [=McCoy=] becomes Beast in this film, but is shown on a television screen as a human in ''Film/X2XMenUnited'', talking to Sebastian Shaw, who should look like Kevin Bacon and also should be dead by the 2000's.

* Charles and Erik briefly have a run-in with Wolverine, despite the original movie seeming to depict them meeting him for the very first time in the 2000's. Wolverine not remembering them is explained away by his memory loss at the end of ''Film/XMenOriginsWolverine'' but it still creates the question of why neither Charles nor Magneto remember ''him'' or explain that they've met before. However, they only met for about five seconds, and they didn't even look him directly in the eye, so after twenty years it makes sense they would have trouble remembering him.

* There is ''one'' thing that inexplicably matches up, however; if Banshee was a teenager in the mid-sixties, it makes sense that Siryn, who is canonically his daughter, appears in the original trilogy.

* Hank [=McCoy=] becomes Beast in this film, but is shown on a television screen (in human form) in ''Film/X2XMenUnited'', talking to Sebastian Shaw, [[spoiler:who should be dead.]]

* In order to make the ages work, Beast would have had to be 60 or so years old during the events of ''Film/XMenTheLastStand'' (Creator/KelseyGrammer was 51 during filming); meanwhile, ''Film/X2XMenUnited'' Hank looks much younger.
* ''Film/XMenDaysOfFuturePast'' eventually solved the problem by providing a CosmicRetcon that explicitly [[spoiler:removes ''The Last Stand'' from continuity along with every other movie that occurs after ''First Class'']]. WordOfGod is that ''Origins: Wolverine'' is also officially CanonDiscontinuity since there is simply no way to fit it into the continuity of the prequels.
* The film contains cameos from what appear to be adolescent versions of Cyclops and Storm in 1962. Not only would this push them into their 40's in the original trilogy, but it is also blatantly contradicted by its own sequel, ''Apocalypse'', which depicts the two as teenagers (and [[TheOtherDarrin played by different teenage actors, no less]]) during the 1980's.

The movie steps on the toes of almost all the previous movies (Creator/MatthewVaughn admitted that it's an UltimateUniverse):

* Magneto obtains the helmet from Shaw and Xavier is fully aware of how it blocks telepathy; in ''Film/XMen1'', Xavier is shocked at Magneto's helmet being able to block his telepathy.
