To create the reality of space with this sense of suspension: nothing's happening, it's endless; we're traveling at 28,000 kilometers an hour but nothing's happening. Nothing! And you have to do that! There are all these rules you have to follow, I've never known anything like it.

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.

I've always wanted to do a space movie.

I like action movies, even though I think action movies are kind of derided now. But there is something extraordinary about action movies, which is absolutely linked to the invention of cinema and what cinema is and why we love it.

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!

That survival instinct, that will to live, that need to get back to life again, is more powerful than any consideration of taste, decency, politeness, manners, civility. Anything. It's such a powerful force.

The individual will to survive is often seen as just that, an individual thing. In fact, it's sort of a gene we all carry and like a network of computers it all contributes in some way to when it's individually needed.
