X-Men: Days of Future Past (2014)

You wanted a First Class sequel? Sike! 

The follow up to 2011's X-Men reboot saw the return of original movie director Brian Singer who decided instead of continuing Matthew Vaughn's prequel film in a satisfying way, that we were going to instead get the third Brian Singer original trilogy movie featuring some of the cast of the last movie. To save the X-Men from a future in which mutants are wiped out by Sentinels, Wolverine must travel back to the 1970s to stop Raven (Mystique) from murdering Bolivar Trask who's death becomes the catalyst for the creation of these weapons of mass destruction.
