It's not so much what you learn about Mumbai, it's what you learn about yourself, really. It's a funny old hippie thing, but it's true as well. You find out a lot about yourself and your tolerance, and about your inclusiveness.

One of the things in the Mary Shelley [Frankenstein] is that the creature tells his story, so this begins with the creature's point of view. So, it literally starts with the creature opening his eyes and is born - but is obviously in his 30s. But because they're the creator and the created we thought it would be really interesting if they could look at each other every other night and play each other's roles.

I always say to anybody who's going over to America for the first time, 'Whatever you do, go and see a popular mainstream film with a big audience.' Because people shout out. You never get that in Britain. Everybody's so quiet, scared to laugh. It's like being in church.

I tend to score with songs from Western pop music.
