Now that her time as the mother of John Connor has come to an end, actress Lena Headey has joined the cast of the upcoming HBO pilot, “A Game of Thrones.”
Headey 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).
Headey also starred in the big-screen epic, “300.”
