Doctor Who has never pretended to be hard science fiction... At best Doctor Who is a fairytale, with fairytale logic about this wonderful man in this big blue box who at the beginning of every story lands somewhere where there is a problem...

The world is always ending for someone. It’s a good line. I give it to the father of the child. He says it to his wife. ‘The world is always ending for someone,’ he says. She is trying to quieten the baby, and does not hear him. I doubt that it would matter if she did.

If you, as a parent, raise your children well, they won't need you anymore. If you did it properly, they go away.

My wife, Amanda, is terribly good at warping reality. She is like a bowling ball on a rubber sheet, and you find yourself living in her universe, doing things that are completely unexpected or unimaginable for you, but you blink and you're up on a stage singing, or wearing a peculiar wig, or writing a book filled with feelings and emotion, or doing something equally as unlikely.

I've learned over the years that everything is more or less the same amount of work, so you may as well set your sights high and try and do something really cool.
