A few months ago, the first trailer for the upcoming film 'X-Men: Days of Future Past' didn't really show us much. It was almost like they released it too early. Director Bryan Singer even said that at the time the trailer was released, the visual effects weren't even near to being finished.

Now, we finally get a good look at the film, and our first look at the Sentinels in action. Also, you get a ton of mutants in this new film, which includes the original X-Men cast and the 'X-Men: First Class' cast.

Watch the new trailer for 'X-Men: Days of Future Past', which opens in theaters on May 23rd, below!
