"I don't want your future," shouts James McAvoy (as the young Charles Xavier) in the full trailer for "X-Men: Days of Future Past," the mother of all X-Men movies. McAvoy doesn't appear to be yelling that money line at Patrick Stewart, but the two screen incarnations of Professor X do have a conversation in "X-Men: Days of Future Past," which also includes roles for Ian McKellen, Michael Fassbender, Jennifer Lawrence, Halle Berry, Nicholas Hoult, Hugh Jackman and pretty much all of your X-Men favorites from the last 14 years. Fox has "X-Men: Days of Future Past" set for release on May 23. Watch the new trailer below.
