This time, our favorite mutants will have to go back in time and join their younger selves to "end this war" before it even begins. But — lo and behold! — it's not as simple as you'd think. There will be hijinks and at some point, The Jacked Man is going to have to open up a can of you-know-what on his own past in what is bound to be the battle of the century. Peter Dinklage also joins the cast, alongside Michael Fassbender, James McAvoy, Nicholas Hoult, Anna Paquin, Ellen Page, Fan Bingbing, and, of course, Sir Ian McKellen and Patrick Stewart. Watch and weep, because it is wonderful, but also because you have to wait until May 23, 2014.
