Cersei Lannister. Devious, treacherous, manipulative, incestuous, blood-thirsty, hate-filled liar. Let's face it, for all we enjoy watching her character, she is all of those things and more. But once upon a time, long before Lena Headey ever donned the regal dresses of King's Landing, she was throwing on a police uniform in a Steve Coogan comedy. The Parole Officer also features Thrones co-star Stephan Dillane (Stannis Baratheon) a decade before they were dropped into Westeros, while Simon Pegg and Ben Miller also star. Headey has taken on some incredibly challenging and intense roles throughout her career, so its nice to see her let her hair down, even if it does seem totally bizarre.
