Re: X-MEN: Days Of Future Past (Casting, Rumors, Pics till release)
Perhaps, through the course of DOFP, certain things will end up differently than they were at the end of First Class or The Last Stand (for instance, maybe at the end of the movie, Professor X, Scott, and Jean are all alive and well in their new altered timeline).
At the end of The Last Stand
, Xavier is alive. Well, however, might be a different story, and there's also the question of whether he retained his powers.
You get hurt, hurt 'em back. You get killed, walk it off.
