People don't really have a relationship with great writing or great production or great art direction or great direction. They just sort of admire it.

We're thrilled to have Maisie Williams joining us on Doctor Who. It's not possible to say too much about who or what she's playing, but she is going to challenge the Doctor in very unexpected ways. This time he might just be out of his depth, and we know Maisie is going to give him exactly the right sort of hell.

The Doctor: Don't blink. Don't even blink. Blink and you're dead. Don't turn your back. Don't look away. And don't blink.

I think of myself as a writer with a sense of humour rather than a comedy writer. Happy to tell a story with lots of jokes in it - I wouldn't know how to do jokes without the story.

Madge: I don't know why I keep shouting at them. The Doctor: Because every time you see them happy you remember how sad they're going to be. And it breaks your heart. Because what's the point in them being happy now if they're going to be sad later. The answer is, of course, because they are going to be sad later. ~ The Doctor, the Widow, and the Wardrobe

The Doctor: This is bad, I don't like this. [kicks console and yells in pain] Never use force, you just embarrass yourself. Unless you're cross, in which case... always use force! Amy: Shall I run and get the manual? The Doctor: I threw it in a supernova. Amy: You threw the manual in a supernova? Why? The Doctor: Because I disagreed with it! Now stop talking to me when I'm cross!

Between the marriages, I shagged my way round television studios like a mechanical digger.
