With the release of one single photo, director Bryan Singer revealed that original X-Men trilogy star Daniel Cudmore is returning as Colossus in X-Men: Days of Future Past, along with new actors Bingbing Fan and BooBoo Stewart. Take a look at the photo, then read on for more information.

Bingbing Fan is set to play Blink, a mutant with the power of teleportation, although it isn't known who BooBoo Stewart is playing. The photo does make one wonder if there are six roles left to be cast, since there are six randomly-blank spots on this casting wall. As we reported earlier today, one of those roles isn't Azazel, after Jason Flemyng revealed he isn't reprising his role from X-Men: First Class.

Bryan Singer is directing from a screenplay by Simon Kinberg, based on a 1980s comic book arc by Chris Claremont and John Byrne. In the comics, the mutants are being hunted by Sentinels in an alternate future, after an important Senator is murdered by the Brotherhood of Evil Mutants.
