When things start becoming second nature, I get a little paranoid because I feel like maybe my craft isn't evolving. I get a lot of gratification when I do something that's really quick. Like if you've got someone who's really twitchy, like Lady Gaga. I have never in my life seen someone move that much in a chair. I said, "Look, your hair's knackered, you wear wigs all the time. Let's cut it off." It took 10 minutes.
