“In this scene, Catwoman wants to whip off the heads of four mannequins. And Michelle’s three months of training really paid off. She performed this difficult and potentially dangerous scene perfectly on the very first take.”

“The trick about it is, it is traveling faster than the speed of sound. So, there’s a certain hazard to it because it can cut skin, it can break bones. She is doing things with the whip that will make Indiana Jones green… that 90 percent of the people who do this for a profession can’t do.”
