Game of Thrones actress Sophie Turner has joined HBO Max’s adaptation of The Staircase.
Inspired by the Netflix true crime documentary series, this star-studded drama already boasts a cast list including Toni Collette, Colin Firth, Juliette Binoche, Rosemarie DeWitt and Parker Posey.
Via Deadline, it’s been announced that Sophie, who played Sansa Stark in all eight seasons of Game of Thrones, will portray one of convicted killer Michael Peterson’s adopted daughters, Margaret Ratliff.

Written by co-executive producers, The Devil All the Time‘s Antonio Campos and American Crime Story‘s Maggie Cohn, the series centres on Michael (played by Firth) and the mysterious death of his wife Kathleen (Collette).
Campos will also direct six of the eight episodes.
Little Fires Everywhere star DeWitt is on board as Kathleen’s sister Candace Zamperini, while The Good Wife‘s Posey will play Freda Black – the assistant district attorney and prosecutor in the murder case.
Elsewhere, Oscar-winner Binoche’s role is being kept quiet for the time being.

In other news, Thrones fans shouldn’t expect Turner to crop up in the first spin-off series titled House of the Dragon, as the series is set 300 years before The Battle of Winterfell.
However, you can expect a cast including Matt Smith, Emma D’Arcy, Paddy Considine and Olivia Cooke.
Game of Thrones seasons 1-8 are available on DVD and Blu-ray. Spin-off House of the Dragon is now filming.
