Michelle Forbes

I did a show called 'Wonderland' a few years back, and I was fortunate enough to spend a full-on two weeks - I'm talking 13-15 hours a day - with the doctors and patients at Bellevue in New York. That served me well for 'Durham County.'

If you look at some shows that have an ugly feel to them, or a nihilistic sort of feel to them, you'll usually find a group of cynical, unhappy, miserable people behind the production. If you see a show that's rather boring, or a cookie-cutter factory show, you'll usually find some pretty uninteresting, boring people behind it.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

I've never had much interest in spinoffery - the idea of writing in someone else's universe generally leaves me cold - but 'Doctor Who' is different. I've grown up with it. It's been part of my life since I was tiny, watching Jon Pertwee on a grainy black and white television in Cornwall and being terrified out of my mind.
