Always changing genres, making very different films is a good idea. It's a way of making yourself feel vulnerable again, getting back to that innocence. As is working within a circumspect budget.

To force yourself out of the comfort zone, the main ingredient is trying to work in a world where you haven't been before, that you don't know the rules of. And that involves a lot of research, so you begin to see where the other people have been, but you are starting from as vulnerable and as low a point as possible.

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.

Both of my sisters have been teachers and they used to say you get asked between 300 and 600 questions every day which you have to answer. That's exactly what directing is. And the vast majority of those questions are not very interesting really, but they need somebody to make a decision - a good one or a bad one - and they follow it.

I'm a big sports fan. Football. Cricket.

I don't want people to sit there and objectively watch the film. I want them to experience it as something that's under their skin, so you try to make the films really tactile.

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.
