Two MAJOR original X-Men stars returning for Days of Future Past

There have been rumblings that some former X-Men cast members could return in the upcoming sequel Days of Future Past. Now we know for sure—and it seems Magneto and Xavier's battle will rage through a few generations this time around.

Bryan Singer has confirmed that X-Men stars Patrick Stewart (Professor X) and Sir Ian McKellen (Magneto) are the latest additions to First Class sequel Days of Future Past, which is said to be a time-jumping story based on the seminal 1980s comic arc of the same name.

James McAvoy (Xavier) and Michael Fassbender (Magneto) took up the characters in the recent prequel, and it'll be amazing to see what happens with all four now in the mix.

Singer confirmed the casting news on Twitter:

Possibly the best part? That last bit. What does he mean by "More to come..."? We don't know, but we can't wait to find out.

WIth original X-Men director Singer back in the saddle tackling this storyline specifically, it looks like the studio is taking a real shot a revitalizing both versions of the franchise with one film—a gutsy and potentially awesome proposition.

What do you think? Could Days of Future Past make up for the mess that was X-Men: The Last Stand?
