Singer: X-Men 2 is an 'inbetwequel'
Bryan Singer has revealed that X-Men: Days Of Future Past is neither a sequel nor a prequel.
The follow-up to Matthew Vaughn's X-Men: First Class is set to involve time travel, with the new generation of stars like James McAvoy and Michael Fassbender sharing screen time with their predecessors Sir Ian McKellen and Sir Patrick Stewart.
Asked about the film's timeline, the director told Empire: "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 3 (X-Men: The Last Stand); and in the past it takes place about ten years after First Class.
"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," he added.
James will reprise his role as Xavier (Professor X), with Michael as Erik Lensherr (Magneto) in the sequel, which also stars Jennifer Lawrence, and Nicholas Hoult with Halle Berry, Hugh Jackman, Ellen Page and Anna Paquin returning from previous X-Men films.
X-Men: Days Of Future Past, which has been filming in Canada, is scheduled to be released in May 2014.
