"It takes place about ten years, give or take, after X-Men 3; and in the past it takes place about ten years after First Class.” Singer also coined a new word for what to call the film, "“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."
Previous reports on the film have revealed it to take place in a few other locations beyond simply America, but Singer says that's just the first layer and the film goes even more places.
“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,” he says. “It’s got scope, but most of the scope is in the breadth of the story.”
Speaking about the "1970s" portion of the film, Singer revealed where we will find Charles Xavier and Magneto at the start of the film: “Charles is in a very dark hole when we meet him, and Erik has been gathering his power.”
