One mutant that is confirmed of course is Professor Charles Xavier, but Patrick Stewart won’t be easing himself back into the chair this time around. Instead, the master telepath will be played by the rather more sprightly James McAvoy.

No news as yet regarding who will play Magneto, but Singer has stressed that the relationship between the two will be key to the film’s story.

“Just doing younger mutants is not enough,” said Singer in an interview with the LA Times. “The story needs to be more than that. I love the relationship between Magneto and Xavier, these two men who have diametrically opposite points of view but still manage to be friends — to a point. They are the ultimate frenemies.”

With a Magneto spin-off also in the offing, will somebody be cast for both movies? And is there a risk that the two films will cover similar ground? Singer remains confident that there is plenty of room for manoeuvre.

“This story would probably utilize some of the Magneto story,"  he told HeatVision, “but no, I don’t see an exhaustion. The X-Men universe is boundless. These are great characters. And as young characters, they are quite different than the characters we have seen in the contemporary movies.”
