Lena Headey is an English actress. Headey's performance in a one-off show when she was 17 caught the attention of a casting agent, who took a photo and asked her to audition. Eventually she got a supporting role alongside Jeremy Irons and Ethan Hawke in the 1992 drama film Waterland and went on to appear with higher-profile actors in major films such as The Remains of the Day, The Jungle Book, Onegin and Aberdeen.
After working steadily as an actress getting small and supporting roles in films throughout the 1990s, she found fame for her lead performances in big-budget films like the fantasy film The Brothers Grimm, in which she acted opposite Matt Damon and Heath Ledger, the action film 300, portraying the role of Gorgo, Queen of Sparta, and the adventure and biographical feature The Red Baron.
She is known for playing the starring role Sarah Connor on Fox's television spin-off of James Cameron's Terminator film series Terminator: The Sarah Connor Chronicles. As of 2011, she appears as Cersei Lannister in HBO's television series Game of Thrones.
