The X-Men: First Class sequel is set to feature time travel.
The makers of the movie have registered the title Days Of Future Past — which is one of the most famous story arcs from the comic book series — with the Motion Picture Association of America (MPAA).
The storyline switches between the present day and a future in which mutants are an outlawed species, following the assassination of Senator Kelly by villain Magneto (Michael Fassbender).
Kitty Pryde manages to warn her future self of the threat and the X-Men embark on a race against time to stop Magneto before it's too late.
Simon Kinberg, who also worked as a screenwriter on X-Men: The Last Stand will write the script while Matthew Vaughn will once again direct.
Vaughn has previously spoken about his ideas for the sequel saying he would only bring in one new character.
He explained: "We will only have one more new character. I won't say who he or she is! But we will only be bringing one more new character in. Because, I think, as Professor X (James McAvoy) is in a wheelchair, Magneto needs to have a nemesis he can fight with."
"Someone that will be his equal. I know who it is. It would be nice if I could say something, but I can't!"
