My problem is that the audience is more fiction-literate than ever. In Shakespeare's day, you probably expected to see a play once or twice in your life; today you experience four or five different kinds of fiction every day. So staying ahead of the audience is impossible.

Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. Now and then, every once in a very long while, every day in a million days, when the wind stands fair and the Doctor comes to call, everybody lives.

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.

Cinema is so slow and boring compared to television.

Well, the world is vastly counted in favour of men at every level - except if you live in a civilised country and you’re sort of educated and middle-class, because then you’re almost certainly junior in your relationship and in a state of permanent, crippled apology. Your preferences are routinely mocked. There’s a huge, unfortunate lack of respect for anything male.

You'll go out of business if you think people are stupid.

I can say with pride verging on smugness that I've got two very successful shows that assume their audience is very smart.
