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

I find the world more absurd now than I did when I was a kid.

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 the acting game, you spend a long time fighting against what the director perceives you to be. And half the time the directors don't know.

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.

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.

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.
