The trouble with a series as it gets older is it can feel like a tradition, and tradition is the enemy of suspense, and it's the enemy of comedy. It's the enemy of everything, really. So you have to shake it up.

Demons run when a good man goes to war. Night will fall and drown the sun when a good man goes to war. Friendship dies and true love lies. Night will fall and the dark will rise when a good man goes to war. Demons run but count the cost; the battle's won but the child is lost.

Sherlock Holmes can be wise and funny. He wasn't, at the beginning. But later on, he's got a bantering relationship with loads of people. He's got a wisdom that he didn't have in the early stage. But he stays on the mountain top, and he will die up there. He's not going to change that.

I like naked women! I'm a bloke! I'm supposed to like them! We're born like that. We like naked women as soon as we're pulled out of one... When Man invented fire, he didn't say "Hey, let's cook!" He said: "Great! Now we can see naked bottoms in the dark!"... The story of male achievement through the ages, feeble though it may have been, has been the story of our struggle to get a better look at your bottoms.

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

I write the kind of stuff I'd like to watch.
