I remember years ago … in the Radio Times there was a little article saying, ‘In this week’s episode the Doctor dodges the Sontarans through the many rooms of the TARDIS.’ I could not wait for Saturday. “But there was a problem with the scenery or something and they shot it all in a disused hospital. And it was so disappointing. And I thought that day, ‘Some day! Somehow, I will do what I can to get into television and do that properly!’ And that worked out. So Michael Pickwoad [Production Designer] goes mad and gives us the TARDIS and gives us all manner of things.
You will go to the heart of the TARDIS. You will see more of the TARDIS more properly than you’ve ever seen it before. It’s all that stuff. The moment I got that title and gave it to Stephen Thompson, who wrote it, it was just the title alone gets you.
