I don't think, generally speaking, people become writers because they were the really good, really cool, attractive kid in class. I'll be honest. This is our revenge for people who were much better looking and more popular than us. I was a bit like that, I suppose.

I hope I won't become hated by geeks everywhere, but I don't really know comic books all that well.

Time travel is always more magical somehow when you go into the past. Traveling into the future is something you do, every day. You're just not going to get very far. So, I rather like the past travel.

Witty and mean is easy - but fond and funny is hard.

Being the only writer on a successful show is very rewarding.

[The Doctor, Capt. Jack and Rose are cornered by the empty children.] The Doctor: Go to your room! Go to your room! I mean it. I'm very, very angry with you. I'm very, very cross! GO! TO! YOUR! ROOM! [The children lurch away and obey him.] I'm really glad that worked. Those would have been terrible last words.
