Two generations of X-Men will join forces for the upcoming X-Men: Days of Future Past. Director Bryan Singer tweeted yesterday that Patrick Stewart and Ian McKellan will reprise their roles as Professor X and Mangeto for the upcoming sequel.
James McAvoy and Michael Fassbender played Xavier and Magneto in First Class, the 2011 reboot of the franchise which was set in the early 1960s.
Days of Future Past is a classic storyline that unfolded in two-issues of Uncanny X-Men in 1981, from writer Chris Claremont and artists John Byrne and Terry Austin. The story was partially set in an alternate future where surviving mutants have been penned in concentration camps, giant robots named Sentinels patrol America, and most of the X-Men have been hunted and killed. In the present day, the X-Men were forced to stop a key event from unfolding in order to keep that future from occurring.
