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.

I tend to score with songs from Western pop music.

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

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.

Everybody expects you to be qualified to talk about your films, but in a way, you're the least qualified person to talk about them. When you're finished, you don't watch them at all.

Theres a certain truth that you do end up making the same film again and again so if you vary the genre you have a chance of breaking that cycle.

Movies are about time. You can take that momentum and manipulate time as well, or you can deliberately slow it down, stop it, and start it again. There is no other art form that does that type of manipulation in that way.
