If you don't expect to like someone and then you do, that's an incredibly exciting moment.

Young Reinette: Monsieur, be careful! The Doctor: It's just a nightmare, Reinette, don't worry, everyone has nightmares. Even monsters under the bed have nightmares! Young Reinette: What do monsters have nightmares about? The Doctor: Me!

Twins are under-represented in the media. Hamlet - never twins. Hamlet Twins Of Denmark. King And Queen Lear. It would work. Come on, more twins on television.

Witty and mean is easy - but fond and funny is hard.

Do you know how you make someone into a Dalek? Subtract Love, add Anger.

The Doctor: Oh, now what's this, then? I love this. A big, flashy-lighty thing. That's what brought me here. Big, flashy-lighty things have got me written all over them. Not actually, but give me time... and a crayon.

The story of Sherlock Holmes, on the surface, is about detection, but in reality, it's about the best of two men who save each other - a lost, washed-up war hero and a man who could end up committing murders instead of solving them. They come together. They become this perfect unit. They become the best friendship ever, and they become heroes. That's what we fall in love with, not Sherlock on his own. No one can love that man on his own, but Sherlock Holmes and Dr. Watson - the best friends ever.
