I haven't got anything against films that are about the minutia of relationships or customs, but I love extremes. I love taking a bunch of characters and it usually is a bunch of characters, and you throw something at them that's usually extreme, like a bag of money, or you send them out to explode a nuclear device on the surface of the sun. And those extremes are wonderful for drama.

I'd love to do a cop film in America. That's a genre I absolutely adore.

I always think, when there's stuff that people don't like, I always say that if I have another success, I'll enjoy it more, but you don't really.

There are three huge, titanic, space movies which if you ever make a film [about space] you cannot avoid. You may want to avoid them but you cannot. I've never known a genre like it where you are dictated to by these films, 2001, Alien, and Tarkovsky's Solaris.

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.

Your first film is always your best film, in a way. There's something about your first film that you never ever get back to, but you should always try. It's that slight sense of not knowing what you're doing, because the technical skills you learn - especially if you have a film that works, that has some kind of success - are beguiling. The temptation is to use them again, and they're not necessarily good storytelling techniques.

To create the reality of space with this sense of suspension: nothing's happening, it's endless; we're traveling at 28,000 kilometers an hour but nothing's happening. Nothing! And you have to do that! There are all these rules you have to follow, I've never known anything like it.
