When it comes to Doctor Who, you'd be hard-pressed to find a bigger fan of the show than Peter Capaldi.
The Twelfth Doctor – who this Christmas handed over the keys to the Tardis to his replacement Jodie Whittaker – has been a devotee of the show since childhood with his adoration of all things Who well documented by the media and fans since he took over the role in 2013.

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.
Take a closer look at the snap and you can also see Gatiss's reflection in the mirror, clearly enjoying the moment too.
Doctor Who will return for a new series next year with Jodie Whittaker – the first female Doctor – at its helm, overseen by new showrunner Chris Chibnall.
