It's hard to say if there's ever been an X-Men film as highly anticipated as the upcoming X-Men: Apocalypse. Ever since [X-Men: First Class](tag:3567490) reset the cinematic timeline audiences have been eagerly anticipating the return to that universe and the chance to see the ultimate formation of the team.
The X-Men team is vast and fluid, members drop in and out all the time and the films have only shown us a very small portion of the comic book characters so far. [X-Men: Apocalypse](tag:1194267) is set to introduce Jubilee (lana Conder), Psylocke (Olivia Munn) and Caliban (Tómas Lemarquis), not to mention the big bad himself - Apocalypse (Oscar Isaac).
Regarding the wider cinematic universe, X-Men producer Simon Kinberg dropped some news a while back that could make things very interesting further down the line...
The Continuity Reset
"The idea is that we’ve sort of reset the timeline after Days of Future Past in some ways, and if not erased, certainly allowed for change from X1, 2, 3, everything from Days of Future Past forward, 1973, everything we set now becomes canon."
The alternate timeline we saw in Days of Future Past is about to get even more prevalent - and it answers a question that many were asking of the original X-Men films, namely, where's the rest of the Marvel Universe?
Now obviously we know where they are (tied up in rights agreements with Marvel Studios/Disney/Sony) but thus far the X-Men have been isolated apart from the wider narrative universe they share in the comics. However, the timeline reset means that the preceding films take place in a different timeline from the events of the first three movies - hence why Jean Gray (Famke Janssen) and Scott Summers (James Marsden) are shown to be still alive at the end of Days of Future Past.
This kind of continuity reset is common in comic books, as it allows for fresh takes on classic characters, and opens up wider avenues for storytelling. (It does make keeping track of things a bit tricker though.) Similarity the X-Men cinematic reset gives the studio a good way to start introducing other characters from the books, namely...
Deadpool, And Gambit
Yep, because again according to Simon Kinberg:
"The Gambit movie, the Deadpool movie, will exist in a world that acknowledges whatever happened in Days of Future Past and moving forward. Doesn’t mean they’ll always interact with those characters, obviously, it’s not like every movie has all the characters, but they all have to exist within the same rules.
There will be interplay between different characters in different movies. We have a clear sense of the directions we want to take them in and in my my mind at least, how we could start to cross-pollinate sort of with those characters that have their standalone movies."
Born of the same procedure that created Wolverine, Deadpool has been affiliated with the X-Men in the comics, sometimes as antagonist, sometimes fighting alongside them, most notably with Wolverine. And with his recent foray into his own solo film being met with thunderous applause the time has never been better to exploit the love for the Merc with the Mouth.
Deadpool has a long history with the X-Men in the comics, he's asked to join and been turned down, been offered membership which he's then turned down and there's been a ton of fights and misunderstandings between them - he's kinda like Spidey to the Avengers (but much more intense).
We've already seen X-Men Colossus (Stefan Kapicic) and Negasonic Teenage Warhead (Brianna Hildebrand) in Deadpool - as well as the X-Mansion and a ton of other X-Men references - so that supports Kinberg's claims for the wider universe.
The mention of Gambit (a.k.a. Remy LeBeau) isn't too surprising either as he's commonly been associated with the X-Men team throughout his comics run - notably as a love interest for Rogue. Like Wade Wilson, his only live action iteration thus far was in X-Men Origins: Wolverine, and his character (portrayed by Taylor Kitsch) was also heavily criticised for being... Well, kinda crap.
But worry not, Gambit is getting his own solo film too - portrayed by Channing Tatum (a weird casting I think, but okay) - to be released October 7, 2016. Deadpool landed 12th February 2016, and will be followed up by X-Men: Apocalypse on May 27, 2016.
