Hannah Murray is a British actress best known for portraying Cassie Ainsworth in the E4 teen drama series Skins (2007–2008; 2013), for which she was the recipient of a BAFTA Audience Award, and Gilly in the HBO series Game of Thrones (2012–present), for which she has been nominated for two Screen Actors Guild Awards. She has received praise for her performances in the Off West End play Martine (2014) and the film Bridgend.
At the age of 16, Murray heard about an audition for young actors in Bristol, and decided to audition for the experience. The auditions were for the E4 teen drama series Skins. She impressed the producers of the series and was cast as Cassie Ainsworth, a gentle and creative but self-destructive teenager with an eating disorder. Murray and April Pearson were the first two to be cast on the show. Murray went on to appear in the first two series, from 2007 to 2008. She left at the end of the show’s second series to make way for a new generation of characters. On the decision to replace the cast, Murray has said that “it would be really silly to be in a teenage drama if you’re no longer a teenager”.
In 2009, Murray appeared in the ITV adaptation of Agatha Christie’s novel Why Didn’t They Ask Evans?, playing Dorothy Savage. She also appeared in the thriller film Womb (2010). Later that year, Murray starred in an adaptation of Enda Walsh’s Chatroom. The film premiered at the 2010 Cannes Film Festival. In early January, she appeared in the British television thriller Above Suspicion: the Red Dahlia, an adaptation of Linda La Plante’s novel, in a small role.
On 8 August 2011, HBO confirmed that Murray would portray Gilly in the second and third seasons of Game of Thrones. She was upgraded to a series regular for the fourth season. Her character is a young woman who has a baby by her own father, and becomes protected by the character Samwell Tarly. In 2012, she appeared in the action thriller film The Numbers Station.
In 2013, Murray appeared in a two-episode feature, in the seventh and final series of Skins, where she reprised her role as a more serious, solemn, and independent adult Cassie Ainsworth. She also starred in the music video for “Your Cover’s Blown” by Belle & Sebastian.
