"The hardest thing to do as an actor is to act without dialogue, and Sebastian Stan did just an incredible job with this character. He gave him so much life, complexity, and texture without dialogue. You really see his wheels turning in this scene."

"He conveyed incredible menace just through movement for a good sixty minutes in the movie. And that is the hardest job of acting—it’s always very difficult to convey emotion without speaking."
