It's been rumored for quite sometime now, but producer Bryan Singer has officially confirmed that the sequel to X-Men: First Class will be titled X-Men: Days Of Future Past, an adaption of the famous storyline by Chris Claremont and John Byrne from the 1980's . Speaking to IGN, Singer said the movie will touch on aspects of the story, while also adding their own spin on it. The story concerns a dystopian future where mutants are outlawed, and those who are not shot on sight are put into internment camps, the result of an assassination attempt on a senator many years in the past. A lone mutant is sent back in time to stop the assassin and prevent the dark future from coming about, encountering the X-Men along the way. It's pretty much The Terminator with mutants (funnily enough it came out three years before The Terminator). This isn't the first time an X-Men movie used a comic storyline as the basis for it's plot. X-Men 2 adapted God Loves, Man Kills, making some changes along the way, the main one being changing bad guy Stryker from an Evangelist to a military Colonel.
Singer also teased the possibility of connectivity between the new sequel and the other films in the X-Men franchise, as Marvel Studios have done, saying, "I think there's a strong desire to broaden out the universe. The X-Men universe on its own is as big as the Marvel universe and I think it's time to reach out and explore it and perhaps even bring some connectivity between the films as Marvel's done so well." While this doesn't exactly mean that Patrick Stewart and Ian McKellen turn up in the future scenes, I can't stop my fanboy brain from imagining that awesome possibility.
The sequel begins shooting in January, with Matthew Vaughn directing, and much of the originals cast returning.
