An online petition has been started by fans, attempting to bring composer Bear McCreary to the attention of HBO and the Game of Thrones producers. McCreary has extensive credits, having composed the music in part or in full for such series as Eureka, Human Target, Terminator: The Sarah Connors Chronicle (starring Lena Headey, cast as Cersei Lannister), and most famously Battlestar Galactica and its spin-offs Battle Star Galactica: The Plan and the currently-airing Caprica.
