‘The Name of the Doctor’ airs on Saturday 18 May on BBC One.

Moffat told CultBox: “It’d be fair to say ‘the 50th starts here’. It begins. It’s quite a dark episode; it’s quite a serious episode. You’ll start to see the Doctor enter a phase of his life that’s going to change things.”

He added: “I assure you I haven’t made the 50th the second part of a story, that would be insane. We start to move the Doctor into a place, and you’ll start to see we’ve been moving him into a place for a while.”
