I'm not a 'Star Wars' geek.

As soon as you think you can do whatever you want and you have whatever great professional in the world waiting to work with you, then you are sunk.

Clearly, you can think back and see that a character has had enormous odds stacked against him and has to overcome them. It's usually a guy, I'm afraid. But then you're setting up a new movie you have amnesia about these meetings, when you've discussed it more analytically.

There's lots of things that can be solved with cash.

You can do anything you like - really - but this Sci-Fi is absolutely disciplined, it's Zen, you have to be absolutely focused in an area. You have to zone into an area and you then you can achieve when you get there. It's really weird!

The great thing about space films generally, with the exception of Apollo 13, is that big stars tend not to work in space and I think that's because space is an equaliser. It makes everyone the same really and suits an ensemble cast and actors who are prepared to work with each other.

It's interesting, the worse things get in cities, the tougher that cities get, the more brutal the humor is. The tougher things people face, the darker the sense of humor gets and I find that incredibly optimistic.
