I would never say never to returning to comedy.

The only thing that may make me different from other people is I have passionate interests outside of work.

But it's healthy - whatever you can do to keep you fresh and awake. Acting's such a ridiculous job and sometimes you need to look at it like that to get a sort of degree of freshness.

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.

If you can jump up onstage and make people laugh, shouldn't you also be able to inhabit a character?

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.
