Russell T Davies has warned that David Tennant’s final scenes on the show will move fans to tears.

Russell told BBC Breakfast on Thursday: “At Christmas… I warn you now get your Kleenex out and your tissues.”

He continued: “We finished the episode yesterday and we were crying our eyes out. It’s very lovely, powerful stuff, it’s David Tennant at his absolute finest.”

Russell will be leaving the show at the same time as Tennant and is to hand the reigns over to lead writer Steven Moffat. On his future projects he insisted that he wouldn’t take on another revival.

He said: “I’ve relaunched and rewritten my favourite show in the world, nothing else could ever compare, so I wouldn’t do anything else, I wouldn’t relaunch anything else but I think people should.

“Doctor Who’s proved how alive these things can become for a new generation so stories should never die.”
