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.

I don't like the way some actors, when playing a nasty character, will try to grab hold of something good about them.

A script is utterly useless in and of itself; it's only of any worth the minute your actors, your designers, your directors come into being.

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.

The acting I got into by doing what we call pantomime, when I was sixteen. And, there were loads of very pretty girls in the show. I realized; I found out very early on, that the lead comic gets the girl. So, that was cool. When I went to university, I studied Economic Social History. And drama. That kind of got me into it. My main passion was to make films. It was never to be an actor. At that time, there weren't many opportunities for a working class Scottish actor. It was kind of an English thing. And it required a certain mannered cerebral acting style that I couldn't relate to.
