Good storytelling for me is not so much technical expertise, which I know is applauded often; it's actually freshness of approach. It does mean you sometimes stumble and fall and make a horrible mess of things in seeking that freshness, but you should always keep trying to do that.

The most extraordinary thing, you'd be given permission for, and then the weirdest, simplest things, you just wouldn't be able to obtain permissions. And it would go on and on and on forever and ever, and there was no way to know. You have to kind of approach it with an open, quite optimistic mind, no matter what's thrown at you, because it will only ever result in damaging the film if you let any kind of despondency get to you.

My dad was a labourer and my mum had exactly the same job as Noel Gallagher's mum - she was a dinner lady at our local school. Everyone comes over from Ireland and they get the same jobs.

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!

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.

I have this theory that your first film is always your best film in some way. I always try to get back to that moment when you're not relying on things you've done before.

Most films that I do, whether successful or not, just fade away. They have their moment in the sun, then they are gone. 'Trainspotting' did not, and especially with journalists. So whenever I launched a new film, I'd end up talking about 'Trainspotting.'
