10 Doctor Who Cameos You Definitely Missed

Over a period of 12 years (from 2005 to 2017), Mark Gatiss penned no less than nine Doctor Who stories, and physically appeared in three: as Richard Lazarus in The Lazarus Experiment, Gantok in The Wedding of River Song, and Archibald Hamish Lethbridge-Stewart in Twice Upon A Time.

But what you might not know is that Gatiss also provided the voice of World War II pilot Danny Boy in Victory of the Daleks – the only instance of him appearing in an episode he’d written, and the first time in the show’s history that a character had been written and performed by the same person.

Gatiss had not written the part with himself in mind, but was offered it late in the day by casting director Andy Pryor. He reprised the role in A Good Man Goes To War, when Danny Boy returned to help take down Demon’s Run.

It’s hardly Gatiss’ most significant contribution to the show, but nevertheless a role he clearly relished playing!
