I would love to do anything involving a good strong character, whether it's in film, TV or theatre. My dream role's already been taken by Keira Knightley in 'Pride and Prejudice.' Growing up, I really wanted to be Lizzie Bennett.

I think you should aim for the stars - and hopefully avoid ending up in the clouds!

I'd live in Glasgow if I could. I can't praise it enough; it's the nicest place I have ever worked and I've worked in a lot of nice places.

I criticise myself an awful lot. I do worry to the point that I don't think it's very healthy. I'm always picking my flaws. It's a terrible anxiety I have. I wish I could pretend nothing fazes me, but it does.

It's funny; it's a real balancing act. In TV, everybody's talking about authenticity. In order to make 'Dirty Jobs' authentic, I really can't be overly informed. The minute I am, I become a host... It's a very tricky business paying a tribute to work, because TV is very bad at it.

I love singing, and I came to absolutely adore it in the later part of my career.

I support workplace clean air. But a federal ban on smoking would mean that you couldn't smoke in your own home. I don't care what people do in their home.

In my career the push has always been to take another step, to try something new.
