The action flick and sure-to-be blockbuster gives shows mutants—past and present-—trying to fight Sentinels from overtaking the world. In an interview with Collider, X-Men: Days of Future past's director said this film "actually delves into being a time travel movie."
"Once I took on that and figured out a methodology for it, I embraced the fact that like Time Machine, Back to the Future, Terminator, Looper, I'm now in that world or trench, but it's a very fun opportunity to see maybe this is a future," Singer said. "When you see the X-Men in this future, it's almost like you start off and it's sort of a dreary 'maybe' future, it's one you hope didn't happen, maybe it won't happen, and that's kind of what it feels like. So I went full out, that's why it's very dark and they're all militant and I wanted to make sure they all looked like they'd been fighting a war for ten years."
