Following the trailer preview from last week, 20th Century Fox has released the second full-length trailer and a new poster for the highly-anticipated X-Men: Days of Future Past. Hugh Jackman returns as Wolverine, who is sent back to the 1970s to stop a war that is brewing in the past, which could have a devastating impact on the present, in an adventure that unites the cast of the original X-Men trilogy with their younger counterparts of 2011's X-Men: First Class. Take a look at the exciting new footage from director Bryan Singer's superhero sequel, which arrives in theaters exactly two months from today, on May 24.

The ultimate X-Men ensemble fights a war for the survival of the species across two time periods in X-Men: Days of Future Past. The characters from the original X-Men film trilogy join forces with their younger selves from X-Men: First Class in an epic battle that must change the past - to save our future.
