X-Men Days of Future Past: Second Trailer Released Online

On the heels of a week of teasers, the second trailer for X-Men-Days of Future Past has been released online, along with a new movie poster. The trailer keeps the same epic tone as the first, but gives a little more clarity to the narrative, which seems to focus on the relationship between Professor X and Magneto once again. 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 beloved 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. X-Men: Days of Future Past comes to theaters May 23, 2014.
