British writer and actor born in 1966, Mark Gatiss is a Darlington man best known for three things:

Gatiss is a long-time big Doctor Who fan, to put it mildly; he has written for seven of the Doctors, wrote and acted in three official approved spoofs and contributed to seven Big Finish Doctor Who audios. Topping all of that though are his writing credits for the television show proper; "The Unquiet Dead" for Nine, "The Idiot's Lantern" for Ten and "Victory of the Daleks" and "Night Terrors" for Eleven.

He provided an uncredited voice for a space spitfire pilot in "Victory of the Daleks" and "A Good Man Goes to War", as well as other roles in "The Lazarus Experiment" and "The Wedding of River Song" (the latter under a pseudonym and heavy prosthetics), making him the only person to write and appear in Doctor Who no less than four times.

And as if that wasn't enough, he's also the first person to play both the Doctor (The Web of Caves, a comedy spoof) and the Master (Sympathy for the Devil, a Big Finish What If audio).

He appeared in a live version of The Quatermass Experiment in 2005 with David Tennant. During a break in rehearsals, Tennant whispered to him that he was the new Doctor that Gatiss would write "The Idiot's Lantern" for.

Is also currently[when?] appearing in the fourth series of Horrible Histories, along with fellow League of Gentlemen stars Reece Shearsmith and Steve Pemberton.

He is also one of the two creators of Sherlock, and plays the character of Mycroft Holmes.
