Peter Dinklage Is a Mutant! (In 'X-Men,' That Is)

We've got to hand it to "X-Men: Days of Future Past" director Bryan Singer, because the guy sure knows how to surround himself with serious talent. First he went and brought back original "X-Men" trilogy stars Ian McKellen, Patrick Stewart, Hugh Jackman and Ellen Page for his time travel epic. Then he signed up "X-Men: First Class" leads Jennifer Lawrence, Nicholas Hoult, James McAvoy and Michael Fassbender. And now?

Well, now he's just added Golden Globe and Emmy winning "Game of Thrones" star Peter Dinklage. Looks like this "Future" is going to be an awesome one.

Singer made the announcement on Twitter late last night, saying "Officially like to welcome #PeterDinklage from #GameOfThrones to #XMEN #DaysofFuturePast Very very excited!"

That, of course, set off an instant storm of speculation over just who Dinklage will be playing. With most of the X-Men already cast, most fans are hoping Dinklage will instead be playing the diminutive adventurer Puck, who in the comics is a member of the Canadian superhero team Alpha Flight and who has a long history with Jackman's Wolverine.

However, with two full teams of X-Men already set to appear in the film, adding Alpha Flight to the mix might just be overkill. Our best guess if Dinklage isn't Puck: A replacement for Sen. Robert Kelly, who in the comics plays a major role in the "Days of Future Past" storyline but who, in the movies, has already been killed off (he's the anti-mutant congressman who gets mutated into a glob of jelly in the first "X-Men" film).

Whatever the case, though, one thing is sure: We can't wait for July 18, 2014 to get here.
