New 'X-Men' movie to be called ...

(CNN) -- The "X-Men: First Class" sequel won't bow until July 2014, but speculating about it is bound to be easier now that producer Bryan Singer has shared the flick's title with fans.

The James McAvoy- and Michael Fassbender-starrer will be called "X-Men: Days of Future Past." The title comes from the '80s comic of the same name and is set in a dystopian future (which should be familiar to "Hunger Games" star Jennifer Lawrence, who plays Mystique in the franchise.)

"There will be elements that will be similar to the original 'Days of Future Past,' but there will also be some original elements," Singer told CNN. "I can't really say more about it. I will only say that it's a very ambitious project and it definitely widens out the X-Men universe."

Singer confirmed that Matthew Vaughn will return to the director's chair, but there's still no word if anyone from "The Last Stand" will show up in the film. (According to Entertainment Weekly, the original comic features Kitty Pryde, the character played by Ellen Page in the 2006 movie.)

"It's at script stage, so it's coming along good," Singer said. "It's going to be cool."
