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

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.

I definitely think the first works best.

I'm always interested in trying to investigate different personalities. I want to keep myself guessing and keep the fear element alive, so that I don't get too comfortable.

I don't know what's going to happen. I'm flavor of the month at the moment, but somebody else is going to roll around the corner in three months' time. I just want to keep working. I can't stop!

What I find really interesting is to try and mix it up, to push myself and try different things. I don't want to stay in my comfort zone. I want to take risks and keep myself scared.
