actor Matt Damon, who plays Odysseus in Christopher Nolan’s interpretation of Homer’s epic tale, had said in an interview that she had “the greatest arms I have ever seen.”

Damon had been discussing one of the film’s pivotal scenes when he gently corrected his interlocutor, who had mistakenly assumed the biceps in the shot were his own: They belonged to Dalton, who some might be surprised to learn is his stunt double.

A shot of Dalton from behind in the scene, holding a sword and ready to pounce at the giants, is used in one of the posters for the movie.

Confirmed. That's a damn fine arm.
