None of us had any idea of how successful Downton was going to be. I thought I was signing up for another period drama that had a slightly modern feel. It had a freedom about it because it was coming out of the head of Julian Fellowes. Anything could happen and generally did.

I would like to do something modern and possibly funny.

As long as I am given the opportunity to keep performing and keep exploring in whatever medium, I'll be happy. As long as I get to spend time with my family, I'll be happy. As long as I can write in some form, I'll be happy. It is the essential things like that I equate with happiness.

We take so many of our freedoms for granted nowadays - I can travel where I like, I can have a baby when I like, I can do any job I want - but I do think chivalry has been lost a little bit.
