Ever since Peter Dinklage was cast in X-Men: Days of Future Past, many have wondered who the Game of Thrones star would play. There was speculation that Dinklage was going to be Puck from Alpha Flight, but it was quickly shot down when Variety reported Dinklage would be the film's villain. Some wondered if Dinklage would do motion-capture for an all-CG character.
In an interview with IGN, director Bryan Singer provided a few hints about Dinklage's role:
It seems likely that Dinklage will play Bolivar Trask, creator of the Sentinels. My money, though, is on Howard the Duck.
