I was nervous about playing a lead part in a Working Title romantic comedy and I was also nervous about the fact that I not only had to take my clothes off, but get my willy out. There's certain things you can do to make yourself look better, but there's nothing you can do about your willy. Your willy is your willy and no amount of working out is going to make your willy look any different. You get what you're given. But I wanted to look my best and to whip myself into any semblance of handsomeness. And that was hard going.

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.

Being kind is the most important thing Ive ever been taught. Thats what my parents always told me - more important than ambition or success is being kind to people. The cornerstone of my life. What I aspire to is to be kind.

Doing Prometheus was what you imagine being an actor is like when you're five. In a spacesuit, on another planet, getting killed by an alien. It was a real treat, it felt like being a part of movie history.

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.

As an actor, you try and be cool, but one of the reasons you become an actor is because you're a film fan. And then you're like, 'Oh my god, Ridley Scott just spoke to me!'

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.
