Once again, James Hibberd has the scoop, revealing that Mark Gatiss—writer and actor on Sherlock, among many other pop favorite shows—will be returning on season 5 to reprise his role as Tycho Nestoris of the Iron Bank of Braavos. Last seen negotiating with Stannis Baratheon over the Bank’s financial support, his appearance in season 5 certainly heralds more use of Braavos and the Iron Bank for this season.
Hibberd also adds that Gatiss will be filming in Croatia next week.
