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

Well we've moved through the funfair a bit – we've done the rollercoaster, now we're on the ghost train.

Hitler: Thank you, whoever you are. I think you just saved my life. The Doctor: Believe me... It was an accident.

If anyone said to me 'invent a new monster so we can sell more toys', I'd kick them out of my office.

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 way you get your script to the right people is that you put it in an envelope. It's easy. The difficult bit is writing something that is so good people will take a punt on a brand new writer.

Think you've seen it all? Think again. Outside those doors, we might see anything. We could find new worlds, terrifying monsters, impossible things. And if you come with me... nothing will ever be the same again!
