So far I haven't really been prominent enough to get critical attention focused on me. So, of course, I fully expect bad reviews, but I will be wracked with misery as a result.

Every time you start a new job, you're starting from the beginning again and it's terrifying. And you feel like you're going to be fired and told to go home and never to darken the doors of these people ever again.

It's quite frightening; the business of trying to be funny is very hairy. In comedy, the potential for humiliation is huge. Trying to be funny and failing is about the most embarrassing thing you can do.

I'm just happy to be a film where for once I don't have to worry about my hair, because my managers are always complaining about my hair looking depressing in my movies. Which is true. I mean, it's true.

It's dangerous talking about yourself too much because you find yourself talking in sound bites.

It's very difficult to find the time or the money for people to organize rehearsals for some movies. It staggers me how little preparation often goes into these scenes which are difficult and complicated. You think, "God, it's crazy. I've never met this person before and here I am having to work at how to do a whole performance on the set." It was great to have a few days of just talking to Michael [Caine] and Daniel [Barber] and thinking about the characters and the relationship between them before we started shooting.

In my first few years as an actor, I took one terrible TV job after another. But even as I laughed off my awful roles and made fun of myself to friends, my work made me cringe - I dreaded anyone's seeing it. I was crushed that I wasn't doing anything I was proud of.
