May 18 (UPI) -- Sophie Turner is currently best known for her role as Sansa Stark on HBO's Game of Thrones but she's moved on from that iconic character.

She's in the United Kingdom shooting a new show Joan for the CW, where she's playing British jewel thief Joan Hannington. The show was announced last year.

Hannington was known as the Godmother. The six-part series set in the '80s is based on Hanningan's 2004 memoir I Am What I Am: The True Story of Britain's Most Notorious Jewel Thief. After her second marriage to antique dealer/professional thief Bennie Hannington (who becomes 'Boisie' in the TV version), the two ultimately stole thousands of British pounds in diamonds and other precious items.

While she and Hannington lived the high life traveling internationally and amassing luxury cars and designer clothes, she ultimately lost both her firstborn child in a custody battle, then her husband when Hannington was killed in an explosion.

Joan takes some liberties with Hannington's real-life story but the CW version is set in the '80s during the couple's heyday.
