Truth is I don't think God on a daily basis. I think politics, science.

A lot of actors aren't particularly good directors. And they're not particularly good with other actors. That's kind of a fallacy.

The Vatican has tried to condemn 'The Magdalene Sisters' as a pack of lies and that I've made it all up - I wish I was that good a dramatist - and in terms of public relations, that was the daftest thing they ever did.

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.

I love acting. It's the one job I know of where you can go in, go through complete catharsis - emotionally, physically sometimes and mentally - and at the end of the day say, 'See you in the pub, guys.

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

I wanted to dismantle the bollocks that there's a military structure to a gang, with a leader, second leader, the good looking one, first babe, second babe. It's far more arbitrary than that and their values shouldn't be romanticised. They aren't something you want to sign up to.
