According to an anonymous tipster, though one called “extremely reliable” by MTV Geek, Peter Dinklage‘s villainous role in X-Men: Days of Future Past will be that of Bolivar Trask.
Trask is the creator of the Sentinels, the mutant-hunting giant robots that play an instrumental role in this story. Some of Trask’s traditional arc seems pretty close to that of William Stryker as presented in X2, so I’d imagine those details would be changed.
Still, it’s very possible, but if it’s right, then we believe Trask isn’t the only big villain in the film. But… stay tuned for more on that. I promise I’ll bring you more as soon as I can.
