You have to just go with your imagination, where your instinct takes you.

Watching people just look out for themselves, I think, is extremely interesting. It goes right back to something like 'The Beggar's Opera' - the underbelly of society, how it operates, and how that reflects their so-called betters.

Life is much weirder than fiction; nothing's more absurd.

It takes a very strong brain to resist the absolutes, the myths that the media and the politicians peddle - the idea that if you are too kind, where does it all end? That not to help someone is somehow a good idea.

There are some people who walk into a room and they oxygenate it, by their very being there's fresh air. Then there are those who come in with the smell of death and they suck the life out.

Every film I've ever worked on, and that includes 'Braveheart' and 'Trainspotting,' I've always witnessed a director having a breakdown. Every director will have a day, without exception, where they just can't do it anymore, they don't know what to say to their cameraman, their cast. It's the sign of real, physical exhaustion.

It's not so much that I want to direct but that I have to. When I write something it terrifies me that if I give it to someone else and it doesn't turn out as it could have done, I'd feel as if I'd orphaned my baby.
