Lena Headey (“Terminator: The Sarah Connor Chronicles,” 300) will co-star in HBO’s fantasy pilot “Game of Thrones,” an adaptation of the George R.R. Martin fantasy book series that chronicles a battle among seven kingdoms and two ruling families for control of the Iron Throne.
She will play Queen Cersei of House Lannister, wife of King Robert (Mark Addy) and sister of twin brother Jaime Lannister (Nikolaj Coster-Waldau) and outsider younger brother Tyrion (Peter Dinkladge).
The cast of the pilot is led by previously cast Sean Bean as battle-weary Ned Stark, who leaves his home to serve the king.
