You're doing The Zero Theorem?
I'm just doing a very small part in it. Someone finally gave him money to do this one, thank God. It's with Christoph Waltz and Tilda Swinton. I'd do anything for Terry. It's been ten years since I last worked with him. I wrote Terry this whole e-mail, because we had this whole conversation about what the character would look like, because the story takes place in the future, but he had a specific look that he wanted, but then I had to [points to shaved head], and I said, "Terry, what should we do?" And he said, "Actually, we can take advantage of the fact that your head is shaved. Why don't we change your hairline?" So he mocked up a picture and sent me a real receding hairline, with white spiked hair. "We might as well take advantage of the fact that you're bald and really do something, present you in a way you've never been seen before."
