I haven't got anything against films that are about the minutia of relationships or customs, but I love extremes.

Brian Cox is the nicest guy, but he's so arrogant.

But interestingly Star City's technology is all 1970s - still. In fact, it's alarming because you think, "You're not going to send someone up into space in something that old, are you?" But it works and it always has worked and it doesn't fail and it's incredibly reliable.

Events in the present can trigger quite a young part of ourselves. If we don't take responsibility and start looking after that young part of ourselves, we can start asking partners to look after that part of ourselves or we wound ourselves.

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.

There is a Steve [Jobs] that Apple would like to actually present to the public. They have a character, Steve, and they want to keep that story going. And it's very important that writers challenge that occasionally and not just trust their parent companies to tell them.

I've always wanted to do a space movie.
