I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
Of all evil I deem you capable: Therefore I want good from you. Verily, I have often laughed at the weaklings who thought themselves good because they had no claws.
I always had this thing, when I was younger especially, I didn't want to do movies that much. I found they took a lot out of you and they were exhausting for me in a lot of ways.
