X-MEN: DAYS OF FUTURE PAST - Instagram Teaser & 12 Pictures

In preparation for the full trailer which will be released on October 29th, director Bryan Singer has released an Instagram teaser and a batch of 12 official images have appeared online (via Empire and Entertainment Weekly). The teaser only offers 7 seconds of scenes from the trailer, but you'll have to admit that it does an excellent job of teasing the upcoming trailer. The images are far more revealing as they offer a first look at some of the film's cast members from both timelines. In case you didn't know, "X-Men: Days of Future Past" features time travel and will reunite characters from both the first X-Men trilogy and the "First Class" prequel.

Wolverine (Hugh Jackman) gets sent back to 1973 to help stop the rise of the Sentinels, giant robots programmed to exterminate mutants. This, of course, means that he will have to join forces with Professor X (James McAvoy), Magneto (Michael Fassbender) and the younger versions of the other mutants we know and love, in order to accomplish his mission.

The film also stars Peter Dinklage, Nicholas Hoult, Jennifer Lawrence, Ian McKellan, Patrick Stewart, Shawn Ashmore, Anna Paquin, Ellen Page, Omar Sy and Halle Berry.

"X-Men: Days of Future Past" opens May 23, 2014.
