"If you’re a long-time Thor fan you know there’s kind of a tradition from time to time of somebody else picking up that hammer. Beta Ray Bill was a horse-faced alien guy who picked up the hammer. At one point Thor was a frog. So I think if we can accept Thor as a frog and a horse-faced alien, we should be able to accept a woman being able to pick up that hammer and wield it for a while, which surprisingly we’ve never really seen before."
