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.

The Doctor...is embarrassingly human for an alien.

I stole your childhood and now I’ve led you by the hand to your death. But the worst thing is, I knew. I knew this would happen. This is what always happens. Forget your faith in me. I took you with me because I was vain. Because I wanted to be adored. Look at you. Glorious Pond, the girl who waited for me. I’m not a hero. I really am just a mad man in a box. And it’s time we saw each other as we really are. Amy Williams, it’s time to stop waiting.

It's the 50th year of Doctor Who and look what's going on! We're up in the sky and under the sea! We're running round the rings of an alien world and then a haunted house. There's new Cybermen, new Ice Warriors and a never before attempted journey to the centre of the TARDIS. And in the finale, the Doctor's greatest secret will at last be revealed! If this wasn't already our most exciting year it would be anyway!

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

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

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