The newest trailer for X-Men: Days of Future Past has hit, and it looks like a true return to form for director Bryan Singer. In this spot, we see for the first time the dystopian future that awaits mutantkind — like in the original 1980 storyline, Bolivar Trask's Sentinels have emerged and are hunting mutants down to the brink of extinction. Many of the major characters from Singer's original run make appearances alongside their First Class forebears, including Hugh Jackman as Wolverine and Halle Berry as a classically punky Storm. The best part, incredibly, is seeing James McAvoy and Michael Fassbender reprise their roles as Professor X and Magneto right alongside their future counterparts, putting in pretty amazing performances as two men at the height of their enmity. May 23rd can't come soon enough.
