So it comes as no surprise that Capaldi bowed out in style. Mark Gatiss – who has written a number of episodes for the BBC sci-fi series and starred as a WWI soldier in the Christmas special – posted a picture of the outgoing Doctor on Twitter after his final episode aired.
It shows Capaldi playing fancy dress on his last day on set, trying on Third Doctor Jon Pertwee’s velvet jacket from Planet of the Daleks. And surprise surprise, the grin on his face is almost as big as the mop of hair on his head.
