Doing a fight sequence in your sweatpants is different than wearing an 80-pound steel thing. I don’t know, you were in leather,” she said to her co-star Chris Hemsworth. “It’s different. [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.
