[Bong Joon-ho'] is quite different but technically, he is as clever as [Alfred] Hitchcock. That's saying something. In humanitarian terms, I think he is much cleverer. He is one of the best directors I've worked with. I absolutely adore working with him.

With [Fred] Zinnemann I did A Man For All Seasons. He was my screen godfather. I'm happy to say he was.

By the time I came to do the final ones [Harry Potter's film], I was working on something that was massively successful. There was a huge difference in indulgence and all sorts of stuff. A very big difference in peoples' attitudes. They were very pleased with themselves. In human terms, it was quite interesting to see the difference.

I turn up in Los Angeles every now and then, so I can get some big money films in order to finance my smaller money films.

I find myself more interested in producing. Not because I'm interested in the financial side of it, but just getting together the right elements to make a film, that side of production. I would not be good on the financial side. It would be a disaster from the beginning.

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.

There are certain people that when they ask you to do a film, you just say, "Where and when?"
