Another actor has been cast in a mystery Game of Thrones role, according to TVLine. Dutch actor Michiel Huisman has joined the HBO show in a role that is being kept entirely under wraps.
Mark Gatiss and Joseph Gatt were cast in similarly secretive roles earlier this year. Via Deadline, however, Huisman is reportedly replacing another actor in the series, indicating that he could be playing any of the series’ many characters.
Huisman’s previous television credits include Nashville and Treme. He has also appeared in a number of Dutch films and television series.
Production began on Game of Thrones’ fourth season last month, and the series will return in spring 2014.
