'Game of Thrones' Casts 'Doctor Who' and 'Sherlock' Writer in Top-Secret Role

Color me intrigued, indeed. 

The upcoming (and already highly anticipated) fourth season of HBO's fantasy drama 'Game of Thrones' has already made one major addition to its cast, but there's plenty more where that came from. In fact, it was revealed on Wednesday that the series is casting a face that should be familiar to television fans -- particularly those who love the popular British shows 'Doctor Who' and 'Sherlock': Mark Gatiss has been cast in a top-secret role for the upcoming season, Entertainment Weekly is reporting. 

Gatiss is a prolific British screenwriter, perhaps best known for his work on 'Doctor Who.' Since the show's revival in 2005, Gatiss has written six episodes, including the controversial "Victory of the Daleks" and the quite good "Cold War" and "The Crimson Horror." (He also had a guest starring role in the episode "The Lazarus Experiment.")

Gatiss's best work, however, is on that other mega-popular British series, 'Sherlock,' which he co-created with 'Doctor Who' showrunner Steven Moffat. He penned the fantastic series 1 finale "The Great Game," along with season 2's "The Hounds of Baskerville." He's already written the first episode of the show's upcoming third series, "The Empty Hearse." Gatiss's work on 'Sherlock' extends from behind the scenes; he has a recurring role on the series as Sherlock's brother Mycroft, a role to which he lends a strangely sympathetic haughtiness. 

So who is Gatiss lined up to play? The first character that came to mind is Lord Mace Tyrell, the head (in name only, since the family also includes Lady Olenna) of the Lannister's biggest rivals and the father of Lady Margery (Natalie Dormer). Gatiss doesn't quite match the book series' physical descriptions of the role, but he certainly seems a good choice for a someone who's a bit out of his depth in the King's Landing power plays. 

Other possibilities include Wildling commander Styr, or Night's Watch blacksmith Donal Noye. But the secrecy surrounding his role seems to indicate to me that he might be a more mysterious character -- fans of the book might envision him as the Kindly Man from Arya's storyline, perhaps. Another choice that's kind of a long shot: one of Balon Greyjoy's siblings, several of which should be popping up this season. 

Who do you think Gatiss will play? 

'Game of Thrones' returns next spring on HBO.
