You can see areas where maybe you got a bit lazy, perhaps, or you see when you were really on form. I think an actor is very like a sportsman in that respect. You have periods where you're in terrific form.

The British tradition, basically, is to go to the character. And the Hollywood tradition, shall we say, is basically to take the character to the performer.

What I like about [Berthold] Brecht, it's very interesting. When Helene Weigel came over and somebody talked about Lotte Lenya and said "well, she wasn't alienating." And Weigel said "No, no, no. Why, Lotte Lenya was so true - who cares?" She said: "Berti only developed the theory of alienation in order to stop bad acting." I heard her say that. Now that's brilliant.

I think you can get better in mathematics on a school level, but when you're talking about being a mathematician, I think that's definitely a gift of genes or whatever.

We shot ['Sailcloth'] five days down in Cornwall, and you couldn't have asked for a more beautiful place. It was a couple of tough days at sea, but when I say tough it was still enjoyable.

Film has changed vastly in the time that I've been an actor, and it's, I think, very much for the better. I think there are just magnificent films now, and they're blossoming in the way that the novel did years ago.

Films don't take as long as people think. 'Harry Potter,' people always used to say, 'Well, my God, do you ever get any time to yourself?' I think I did, in 'Harry Potter,' over a 12 year period I did five days. So it's not exactly exhausting.
