Mark Gatiss (born 17 October 1966) is an English actor, screenwriter and novelist. He is best known as a member of the comedy team The League of Gentlemen, and has both written for and acted in the TV series Doctor Who and Sherlock.
Fulfilling a lifelong dream, Gatiss has written three episodes for the 2005-revived BBC television series Doctor Who. His first, "The Unquiet Dead", aired on 9 April 2005; the second, "The Idiot's Lantern", aired on 27 May 2006 as part of the second series. In addition, Gatiss was the narrator for the 2006 season of documentary series Doctor Who Confidential, additionally appearing as an on-screen presenter in the edition devoted to his episode. Gatiss did not contribute a script to the third series, but appeared in the episode "The Lazarus Experiment", as Professor Lazarus. After his submitted script for the fourth series, involving Nazis and the British Museum, was replaced at the last minute with "The Fires of Pompeii", he eventually returned to the programme in 2010, writing the (also World War II-themed) episode "Victory of the Daleks" for the fifth series, in which he also appears uncredited as the voice of "Danny Boy". It has also been confirmed that Gatiss will be writing an episode for the 2011 season of Doctor Who, although details about the story are yet to be revealed.[19]
Gatiss wrote an episode of Sherlock, a modern day Sherlock Holmes series co-produced by him and Steven Moffat. The unaired pilot was shot in January 2009 and a full series was commissioned. This was aired in August 2010 and consisted of 3 episodes. Gatiss also starred in these as Holmes' older brother Mycroft. A second series has been confirmed, but dates have yet to be decided, since both Gatiss and Moffatt have additional commitments.[20]
Gatiss also wrote and performed the comedy sketches The Web of Caves, The Kidnappers and The Pitch of Fear for the BBC's "Doctor Who Night" in 1999 with Little Britain's David Walliams, and played the Master in the Doctor Who Unbound play Sympathy for the Devil under the name "Sam Kisgart", a pseudonym he later used for a column in Doctor Who Magazine. (The pseudonym is an anagram of "Mark Gatiss", a nod to Anthony Ainley, who was sometimes credited under an anagram to conceal the Master's identity from the viewers.) The pseudonym was used again in television listings magazines when he appeared in episode four of Psychoville, so as not to spoil his surprise appearance in advance.
In mainstream print, Gatiss is responsible for an acclaimed biography of the film director James Whale. His first non-Doctor Who novel, The Vesuvius Club, was published in 2004, for which he was nominated in the category of Best Newcomer in the 2006 British Book Awards. A follow up, The Devil in Amber, was released on 6 November 2006. It transports the main character, Lucifer Box, from the Edwardian era in the first book to the roaring Twenties/Thirties. A third and final Lucifer Box novel, Black Butterfly, was published on 3 November 2008 by Simon & Schuster.[21] In this the protagonist finds himself serving Queen Elizabeth II, in the Cold War era.
Gatiss also wrote, co-produced and appeared in Crooked House, a ghost story that was broadcast on BBC Four during Christmas 2008.
