Everyone's crazy anyway. And those who think they aren't, are the ones who are even crazier - because they're in denial.

There's so much going on in the world. There's so much information being thrown at us - so many things are being sold to us, and we're being told how we should appear and how to be more successful, blah, blah, blah. How does that manifest itself? In the pressures, the stress, this need to escape.

We feel a lot of pressure about looking silly or appearing weak, whatever that means, or being a failure. You have to keep in your head: what's the worst that can happen?

The actors I looked up to when I was a teenager, they all just disappeared into different characters.

We did a lot of that in drama school: intellectualising and maybe justifying your position. 'I am a thinking actor and I have thought this through' - well, just do it. I much prefer the doing aspect.

Sometimes if I stick in a character too much I feel like I might start to get blinkered, because I'm making my decisions too definite.

'Hunger' definitely changed my life, in terms of being recognized by filmmakers, since that was very much a filmmakers' film.
