HBO's "Game of Thrones" has reportedly cast Theon Greyjoy's pillaging uncle Euron Greyjoy.

The fan site Watchers on the Wall reports Danish actor Pilou Asbæk ("The Borgias") was spotted in Ballintoy, Northern Ireland, shooting a pivotal scene from George R.R. Martin's novel "A Feast for Crows."

Balon Greyjoy's younger brother, Euron is ruthless, one-eye pirate who captains the Silence, a warship manned by crew members whose tongues have been removed by him.
