I watched what I ate for a bit and did a bit of exercise. I wanted to look alright because I knew I had to take my clothes off and I knew I was starring alongside some extremely attractive women! I think it was Humphrey Bogart who said that the only reason people found him attractive was because of the attractive women he played opposite. So, as audience member you go: "Well, if she would find him attractive, then surely I must too!" Playing opposite beautiful actress of the calibre of Rose Byrne and Anna Faris is amazing - it does a lot of the work for you.

When you do a film, you get picked up in a car, lunch is free. Theatre is really hard, and you get absolutely no money.

For a man, there's a big responsibility that comes with having a boy because men are made by their fathers. If you've got a good productive man around it's better. I have such a close relationship with my dad and that responsibility to produce a good man is something I think about.

One of the biggest gifts you can give a child is confidence, because confidence will take you miles - more than talent, more than anything else. So yes, I want my children to have confidence and to be kind.

I've done loads of things people have never seen, dramas on BBC4 and plays upstairs at the Royal Court and the Bush, and because I didn't go to drama school, they gave me an education.

My dad's one of the funniest men in the world. I grew up with him making me laugh so much I'd beg him to stop.

Every audition I get, I agonise over and I put everything I can into it.
