In this age of comic-book-based movies ruling the multiplex, it is little wonder that the reigning box office champ is X-Men: Days of Future Past, the latest in the 20th Century Fox’s X-Men franchise. The movie effectively wraps up the last four X-men movies in a nice little package, incorporating the actors from the first three X-Men movies and the actors who played the younger versions of them in the last one. It is all very neat and tidy, except for two glaring discrepancies that just about every fan noticed: the claws and Professor X.
Continuity is that aspect of storytelling in which facts and events set up in early stories are accounted for in later stories using the same characters. It is essential in soap operas and movies sequels and to a slightly lesser extent in TV series (of course the TV serial has made a resurgence, hence the “previously on [insert show title here]). When something significant happens to a major character, the viewer has to accept it as a fact of life for the character. This is why writers rarely kill off a principal character: the viewers then expect not to see them again (exception for Southpark’s Kenny).
The character Wolverine, played in all movies by Hugh Jackman, has two spinoff movies of his own, X-Men Origins: Wolverine and The Wolverine. In the latter film, Wolverine’s adamantium claws are severed (an impossibility, by the way) by the Silver Samurai, to be regenerated as bone claws by his mutant healing ability. At the end of that film, in a post-credits scene, Wolverine is approached by Professor X and Magneto asking for his help.
Jump ahead to X-Men: Days of Future Passed and Wolverine is helping the X-Men fight a losing war against mutant hunting robots called Sentinels. The problem is that Wolverine has his adamantium claws back. This begs the question of how that happened. The movie says nothing of it, he is just happily shredding away as if he never lost the metal claws.
Of course, the plot of the film involves Wolverine sending his consciousness back in time to take over his younger body to prevent the advent of the Sentinels in the first place, and in this younger body, he had not yet acquired the adamantium in his bones. But the future self has the metal claws. Brian Singer, the director of the X-Men films offered a half-hearted possibility: perhaps Magneto helped restore his claws. He did not say this definitively what happened. He said nothing definitive.
The other issue is Professor X. He was killed by the Phoenix in X-Men 3: The Last Stand. Although in the end, we hear some other person speaking in his voice; we saw the Professor’s body disintegrate, so it cannot be his body the voice is coming from. Yet at the end of The Wolverine, Professor X is back in his body—complete with wheel chair—asking Wolverine for help. Now, comic book characters have an affinity for coming back from the dead. Barry Allen’s Flash was killed in the 90’s and he got better. Superman was killed by Doomsday and he got better. But in every one of those cases, the resurrection was explained (albeit sometimes very flimsily) by some plot device like time travel or alternate realities or parallel universes or cloning or something. In X-Men: Days of Future Past, there is no explanation of how this happened. Perhaps Brian Singer will suggest that Professor X is related to Kenny.
So, while Days of Future Passed is a very enjoyable film, it leaves two unresolved plot holes that the viewer will have to fill in on their own.
