Previously starring in '300' as Queen Gorgo, the British actress is taking another royal role in the HBO project.
Lena Headey has locked a new destination in her TV career. The Sarah Connor of FOX's recently-canceled "Terminator: The Sarah Connor Chronicles" moves on to an HBO pilot called "Game of Thrones" which is adapted from George R.R. Martin's book series of the same name. It is a fantasy chronicling the battle among seven kings and two ruling families for control of the Iron Throne.
Headey will be Queen Cersei of House Lennister. A wife of King Robert, Cersei is "every bit as smart, cunning and devious as the powerful men around her." She is the sister of twin brother Jamie Lannister whom she is having an incestuous relationship with in the book. The show, however, will follow largely Ned Stark who leaves his home to serve the king.
HBO has not picked it up as a series and has not determined a premiere date but the shooting will begin shortly in Ireland. Other actors cast in the show are Mark Addy, Peter Dinklage, Nikolaj Coster-Waldau, Sean Bean and Jennifer Ehle.
Lena Headey is the latest "Terminator" star to get a new casting role following the cancellation. Summer Glau has a recurring role in "Dollhouse", Thomas Dekker is going to "A Nightmare on Elm Street" while Brian Austin Green is taking guest starring role in "Smallville".
