The actor is joining the fourth season of “Game of Thrones,” although his role is being kept under wraps.
The new season will reportedly be adapted from the second half of “A Storm of Swords,” the third book in George R.R. Martin’s “A Song of Ice and Fire” series.
Other newcomers to “Games” this season include Joseph Gatt, Mark Gatiss (“Sherlock”), and Indira Varma (“Rome”), who will play Ellaria Sand.
HBO has yet to reveal when “Game of Thrones” will return, but it will likely be in the spring.
