Mark Gatiss has spent three decades inside Doctor Who from every possible angle. He wrote nine episodes of the modern series, appeared on screen five times, and wrote An Adventure in Space and Time, the BBC’s own dramatization of the show’s 1963 creation. Before any of that, he was a working actor and comedy writer with The League of Gentlemen, the sketch troupe he built alongside Steve Pemberton, Reece Shearsmith, and Jeremy Dyson. In 2010 he co-created Sherlock with Steven Moffat and played Mycroft Holmes across its run. Few people alive have a longer relationship with this franchise.
