'Upstairs Downstairs' and 'Downton Abbey' appeal to people because they're about our history, they look so beautiful, are written by amazing writers and have high production values.

I prefer watching movies on the sofa rather than sitting next to Bob Geldof at a premiere and wanting to kill yourself.

I am delighted to join Doctor Who and to be working with this incredible team. Ms Delphox is a great character and someone I've had a lot of fun playing.

I'm a mother of three children, and we do make mistakes.

Im a size 12 and Im very happy with it.

There's nowhere to hide in the theatre. You can't be the one in rehearsal who doesn't know their lines.

I think if you do a lot of interviews, you're laying yourself open. If you put yourself out, accept every invitation to every premiere, then you can't really complain when people knock on your front door and photograph you in the street.
