Sophie Turner joins HBO Max’s ‘The Staircase’

Game of Thrones star Sophie Turner is returning to HBO Max in the true-crime documentary series The Staircase. 

According to a Variety report, The Staircase is based on the true story of American novelist Michael Peterson who was accused of murdering his wife Kathleen in 2001, after she was found dead at the bottom of a staircase in their home. Police, however, suspected that Peterson killed her and staged the scene to look like an accident. 

It was first adapted as a documentary in 2004 by director Jean-Xavier de Lestrade, who was granted access to the case. 

Colin Firth is cast as Peterson in the HBO Max version while Toni Collette plays his wife Kathleen. Turner will play Margaret Ratliff, one of Peterson’s adopted daughters. 

Parker Posey, Juliette Binoche, and Rosemarie DeWitt complete the cast line-up. The eight-episode series is written and produced by showrunners Antonio Campos and Maggie Cohn. 

A release date has yet to be announced. 

Turner is best known for her role as Sansa Stark in Game of Thrones, where she earned an Emmy nomination for best supporting actress in a drama. She also starred as Jean Grey in X-Men: Apocalypse and X-Men: Dark Phoenix. – Rappler.com
