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

I did 'Deathly Hallows' so my kids could get on the 'Harry Potter' set. They met Daniel Radcliffe, who was a darling and couldn't have been nicer to them so I'm a hero right now.

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 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.

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.

In terms of popular cinema, 'One Flew Over the Cuckoo's Nest' is as near perfection as I can think of.

There's no such thing as an actor giving positive criticism to a director. The minute you say 'Don't you think it would look nicer', that director's going to hate your guts. Particularly if it's a good idea.
