"The truth of it is that everyone lies when they leave Doctor Who and says they've moved on. I mean, I've been thinking about it since I was three, so there's no way you stop thinking about it.
The reason I've worked on 34 programmes in my life is because I don't normally like continuing series. I like looking at a new set of challenges every time and a blank page – but Doctor Who is always a blank page.
There are things coming up that are brand new ways of telling the stories that have never been done before, so it just feels new. I wouldn't go back if it wasn't feeling new. But that's the thing about Doctor Who – every episode is new. I'm sitting here now, 10 pages away from a climax thinking, 'God, I've never written in this territory before – this is strange and new' – so it's always new. It's a self-renewing show."
