You don’t just give up. You don’t just let things happen. You make a stand! You say no! You have the guts to do what’s right, even when everyone else just runs away.

Nothing can ever be a rule in drama, because then you're saying certain things won't ever happen, and that would be very boring.

You should always waste time when you don't have any. Time is not the boss of you. Rule 408.

Rule 1: The Doctor lies.

The Doctor: It's my nose; it has special powers. Nancy: Yeah? That why it's so...? The Doctor: What? Nancy: Nothing. The Doctor: What? Nancy: Nothing. Do your ears have special powers too?

Sherlock Holmes becomes more human and more adept at fitting in with a lot of people, but he remains separate from the human race because he finds that a better place to observe that from. He stays on the mountain top because there, he can see clearly.

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.
