20th Century Fox has released a pair of new character posters for X-Men: Days of Future Past.  The follow-up finds Wolverine (Hugh Jackman) having his consciousness sent back to 1973 in order to help Professor X (James McAvoy), Magneto (Michael Fassbender), and the rest of the X-Men: First Class crew stop Bolivar Trask (Peter Dinklage) and the rise of the Sentinels, giant robots programmed to exterminate mutants.  These posters feature characters from the "future" part of title—Colossus (Daniel Cudmore), Blink (Bingbing Fan), Iceman (Shawn Ashmore), and Kitty Pryde (Ellen Page).  I assume these characters will be cameos except for Kitty, whose power allows Wolverine's mind to travel back to this 1973 body.

Hit the jump to check out the posters.  The film also stars Jennifer Lawrence, Nicholas Hoult, Patrick Stewart, Ian McKellen, Evan Peters, Halle Berry, Lucas Till, Omar Sy, and Adan Canto.  X-Men: Days of Future Past opens in 2D and 3D on May 23rd.

Here’s the official synopsis for X-Men: Days of Future Past:
