Sophie Turner

Turner was born in Northampton, England on 21 February 1996, the daughter of Sally, a nursery school teacher, and Andrew, who works for a pallet distribution company. She moved to Chesterton, Warwickshire when she was 2 years old. She attended Warwick Prep School until she was 11, and later attended the independent The King's High School for Girls. Turner has been a member of the Playbox Theatre Company since she was 3 years old. She has two older brothers. Her twin died in utero.

She grew up in a large Edwardian house, near Leamington Spa, saying, "My childhood was pretty fun. We had pigsties, barns and a paddock, and used to muck around in the mud." Turner had a tutor on the set of Game of Thrones until age 16. She achieved five GCSE A-grades and four Bs, including a B in Drama. Turner was cast as Sansa Stark, a young noblewoman, in the HBO fantasy drama series Game of Thrones in August 2009. Filming began in July 2010, when Turner was 14 years old. Sansa was Turner's first television role. Turner's drama teacher encouraged her to audition for the part, and she dyed her blonde hair auburn for the role, although in season 7 she began wearing wigs. In 2012, she was nominated for the Young Artist Award for Best Performance in a TV Series – Supporting Young Actress for her performance as Sansa, alongside her on-screen sister, Maisie Williams. Turner appeared in all eight broadcast seasons.

While playing Sansa Stark, Turner was told to lose weight and she said she suffered from mental health problems while spending her teenage years on screen. She also had an eating disorder.

In 2013, she had her first movie role as the lead character in the independent thriller film Another Me, based on the novel of the same name by Catherine MacPhail. She starred as Adeline March in the 2013 television film The Thirteenth Tale.

In 2013, she was cast in the comedy film Barely Lethal, alongside Hailee Steinfeld, which was released on 29 May 2015 in a limited release and through video on demand.

Turner also narrated the audiobook version of the Lev Grossman short story ‘The Girl in the Mirror’, which was included in the short fiction anthology Dangerous Women and was edited by George R. R. Martin. In 2014, she narrated the audiobook City of Heavenly Fire by Cassandra Clare. The same year, she was the face of Karen Millen's "The Journey" campaign. Turner played mutant Jean Grey in X-Men: Apocalypse, which was released in May 2016 to mixed critical success. During summer 2016, she hosted the web video Powershift in partnership with the Huffington Post.

In March 2017, she announced she had become patron of Women for Women, an organisation that supports female war survivors. In August 2017, Turner said she believed her social media following was responsible for her successful casting in an unnamed project rather than her abilities as an actress, saying, "[I]t was between me and another girl who is a far better actress than I am, far better, but I had the followers, so I got the job." In June 2017, she began a collaboration with Wella Hair, becoming its first international brand ambassador.

In November 2017, Turner was cast to play Juliane Koepcke in the movie Girl Who Fell From the Sky. She is also attached to produce the movie. In March and April 2018, she filmed the independent film Heavy in Toronto, Ontario, Canada. Turner reprised her role as Jean Grey in the X-Men film Dark Phoenix, which takes place in 1992 and follows the events of Apocalypse. The film was released in June 2019.

She has been featured in print work for the luxury designer brand Louis Vuitton. In September 2019, Turner was cast in the thriller television show Survive.

In 2022, Turner appeared in a minor role as Erica in the teen black comedy Do Revenge. Turner figures in a pivotal scene where her character is accused of drug possession and has an "over-the-top" reaction. The scene went viral due to Turner's delivery of the line, which she admitted was intentionally played to emulate cinema outbursts from actors like Leonardo DiCaprio and Jack Nicholson.

In 2024, Turner starred in the ITV serial drama Joan acting the lead role as diamond thief Joan Hannington, alongside Frank Dillane as Joan's husband Boisie Hannington.
