New 'X-Men' Trailer: 'We Now Find Ourselves on the Edge of Extinction' (Video)

The new trailer for this summer's "X-Men: Days of Future Past" reveals more about the future Wolverine is trying to prevent -- and finally lets fans see a peek at the Sentinels in action.

The new trailer for X-Men: Days of Future Past — officially, only the second “real” trailer, despite the many social media clips and teases to date — has been released, giving fans their best look at the dystopian war between humans and mutants yet.

“Mutants — we now find ourselves on the edge of extinction,” Patrick Stewart’s Charles Xavier explains as we see the world that Wolverine (Hugh Jackman) is attempting to change through time travel. As we see X-Men in both of the time frames from the movie in action, we also get our first (fleeting) glimpse of the robotic Sentinels in motion, including one that looks like a particularly unexpected addition.

More than any of the earlier glimpses into the movie, this trailer gives an idea of the scope of Days of Future Past: not only what’s at stake in terms of Wolverine’s mission, but also the number of characters who’ll appear in the movie, and what they’re up against. With a little over two months until the release of the movie, it’s a good reminder that Captain America may be saving America and Spider-Man New York City, but this time around, the X-Men are saving the world — and the future.

X-Men: Days of Future Past is released May 23.
