X-Men: Days of Future Past

In a dystopian future, mutants and their human allies are hunted by powerful robots. The remaining mutants converge on a Chinese monastery, where Professor Xavier reveals that the Sentinels, created using Mystique's DNA, are their greatest threat. Xavier proposes a plan to send Wolverine back in time to 1973 to prevent the Sentinel Program's creation, as only Wolverine can survive the time travel.
