Lena Headey (born 3 October 1973) is an English actress. She is known for playing the starring role Sarah Connor on Fox's television spin-off of James Cameron's popular Terminator film series Terminator: The Sarah Connor Chronicles (2008–2009). She currently appears as Cersei Lannister in HBO's television series Game of Thrones (2011), a series that has received universal acclaim from both critics and audience.
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 and eventually she got a supporting role alongside Jeremy Irons and Ethan Hawke in the 1992 British drama film Waterland and went on to appear with higher-profile actors in major films such as The Remains of the Day (1993), The Jungle Book (1994), Onegin (1999) and Aberdeen (2000). 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 motion pictures that became well-known like the fantasy film The Brothers Grimm (2005), in which she acted opposite Matt Damon and Heath Ledger, the action period film 300 (2007), portraying the role of Queen Gorgo and the adventure and biopic feature The Red Baron (2008).
