“The costumes were more damaging than the actual fight sequences,” Theron revealed. “I was way more bruised from my costume than I was from [fighting with Stewart].

[Stewart] was in full metal, I was in full metal, just getting down, it took us four hours,” she said, speaking of the complex setting involved in filming her showdown with Stewart.
