Peter Dinklage Joins X-Men: Days of Future Past

Casting all the original X-Men stars isn't Days of Future Past's only trick. Director Bryan Singer also has the ol' "let's get Game of Thrones badass Peter Dinklage into the mix" up his sleeve, as tweeted on Wednesday evening. Dinklage will take on "a key role," Deadline reports. Speculation seems to be geared toward Puck, from Marvel's Alpha Fight series.
