Time travel movies can be tricky, but with a movie like X-Men: Days of Future Past, which connects both the original X-Men trilogy and the 2011 prequel X-Men: First Class, the story can be even more complicated. Thankfully, director Bryan Singer recently broke down both the past and future time lines in this highly-anticipated sequel, revealing what time each thread in this story takes place, while coining a new term for the movie.

But, before we get to that, the director sent out the latest photo from the set, featuring what appears to be Jennifer Lawrence's Mystique choking out one of her enemies. Take a look at the photo, then read on to see what the filmmaker had to say about his sequel's timeline.

"I'd say it's not a sequel to one of the others. It's an inbetwequel - that's what I call it, for lack of a better word. It takes place about ten years, give or take, after X-Men: The Last Stand; and in the past it takes place about ten years after X-Men: First Class."

The filmmaker also teased some of the international locations used in this adaptation of Chris Claremont and John Byrne's beloved comic book series.

"It takes place in the future and the past and then all over the world, from Russia to China, then France, and Washington, New York. It's got scope, but most of the scope is in the breadth of the story."

Bryan Singer also spoke about the different places James McAvoy's Charles Xavier and Michael Fassbender's Erik Lehnsherr are in the story.

"They're in a radically different place. Charles is in a very dark hole when we meet him, and Erik has been gathering his power."

The filmmaker talked about how Ellen Page's Kitty Pryde/Shadowcat has an important role in this follow-up, whose power makes travelling through time possible, along with Hugh Jackman's The Wolverine.

"She's the prime facilitator - it's her power that enables that to happen. But it's Wolverine who has the strength and the stamina to be able to go back on this journey."
