New X-Men: Days of Future Past Trailer + Poster

20th Century Fox is stepping up the marketing and showing off just how awesomely dark and action packed X-Men: Days of Future Past is going to be. They released a new darker trailer for it along with a well....let's put it as ill-advised layered poster. *Prof. X is farting a trail of fire by the looks of it*.

Wolverine has his consciousness sent back to 1973 to convince and help young Professor X (James McAvoy) and Magneto (Michael Fassbender), and the rest of the First Class team stop Bolivar Trask (Peter Dinklage) from starting the rise of the Sentinels, giant cool robots programmed to kill all mutants.

Days of Future Past will have the "big comic-book tentpole film of the summer" in it's sights when it hits theaters on May 23rd.
