Having seen Justin's work on Bleak House, I knew that he'd be incredibly well prepared and interesting stylistically for this and that was definitely the case. It's very liberating for actors - and I can only speak for myself here - but he creates a very loose environment and he's a great collaborator.

It's got to be a challenge but at the same time you have to feel as though you can play them - it's really dangerous to want to be a part of something just because you think it's going to be great. I've been sent plenty of scripts where I've known that it's going to be a great film and a successful one, but I just couldn't convince myself that I was the right person for the part. So, I think you have to be careful with that.

A girl's got to be fun. It's the one bit of advice I always give to friends of mine who are thinking of getting married.

I think there are times when you walk onto a set you can potentially be either intimidated or distracted by what's going on around you.

I think if you had to map that out at the beginning and you said, "Right, sit down, this is what you're going to be doing," you'd probably freak out. But I'm someone who really enjoys not being himself. So if you consider that, then it all sort of makes sense.

Abs are for people with no friends.

Each time you go to the same track you know whether you're improving or whether you're not... it's not open to interpretation. It's measurable - unlike acting.
