It's a question of keeping one's eyes and ears open and watching how other people play the game. They're watching me too, to see what my attitude is like.

People like Tywin Lannister are very much victims of that system, and of that environment: 'This is my place, don't threaten it'. I don't know how relevant that is to today. Politics is the most corrupt profession on earth, no matter where you are.

I have to admit that I haven't read any of the books [of George Martin's "Game of Thrones"] and I don't refer to them. Apart from anything else they're very thick [in size] and they frighten me. A terrifying prospect.

On an independent film you're lucky if you get one, but ostensibly the job is the same. There's very little difference, apart from the knowledge that there's a captive audience at the end of it - which you can't always guarantee with a movie.

Most films are written and made with a hero around 35, or even 25.

I was a window dresser for Burton's once. What really put me off was the area manager coming round and saying, Charles, I think you're a natch at this.
