Mark Gatiss was cast in “Game of Thrones” back in July, but his role remained a mystery until now. There had been some speculation he could play big Season 4 roles like Mace Tyrell or Aeron Greyjoy, but it turns out his role is something else entirely.
The “Sherlock” actor’s official CV (via Hypable) shows that Gatiss will actually be playing Tycho Nestoris in the upcoming season of the HBO hit show. Nestoris is a character who wasn’t introduced in the “A Song of Ice and Fire” book series until book five, “A Dance With Dragons.” It’s an interesting choice for showrunners David Benioff and D.B. Weiss to bring Nestoris into the show now, when it’s still dealing with the events of book three, “A Storm of Swords.”
Nestoris is a representative of the Iron Bank of Braavos, an institution that was only introduced in “Game of Thrones” Season 3. When Tyrion Lannister took over as Master of Coin from Petyr Baelish, he realized that the reason Littlefinger always managed to find money for the Crown was because he was borrowing tens of millions of Gold Dragons from the Iron Bank. As Tyrion noted, the Iron Bank always manages to get back the money it’s lent out, even if that means funding the enemies of the rulers who are in debt to it.
Gatiss previously said he only shot for about a week in Belfast, so it doesn’t seem likely that he has a big role in Season 4. If anything, his appearance will probably be a way to keep the Iron Bank’s presence alive and threatening in “Game of Thrones.” Nestoris also does have a bigger role to play in later “Game of Thrones” seasons. Expect Gatiss to look different than his usual, as Tycho Nestoris is described in the novels as having a thin incredibly long beard and wearing outfits that go heavy on the purple.
Also new in “Game of Thrones” Season 4 are Roger Ashton-Griffiths as Mace Tyrell, Pedro Pascal as Oberyn Martell, Indira Varma as Ellaria Sand, and Joseph Gatt in an undisclosed role. Meanwhile, Michiel Huisman has joined the cast to reportedly replace Ed Skrein as Daario Naharis and Hafthor Julius Bjornsson will now play Ser Gregor Clegane, aka the Mountain.
“Game of Thrones” returns to HBO with Season 4 in Spring 2014.
