You use elements of noir, but you don't want it to be too noir-ish. You don't want it to be advertised as though you're asking people to go and watch an updated noir. I don't think they'll go do that. They want to see a modern story.

A lot of film directors are quite scared of actors. They are a bit of a nightmare sometimes, but I like them. It looks like cunning, but you try to get extra things from them all the time, by stealth, by making them feel confident, so they trust you and you can push a bit.

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.

I've never done a film before where every single person in the audience knows the ending. I mean suspense, twists are almost impossible these days. People are blogging your endings from their cinema seats.

I kind of call myself an atheist, I suppose - although quite a spiritual atheist, I hope.

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.

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.
