Sophie Turner returning to the HBO family to star in The Staircase

The Hollywood Reporter

The Game of Thrones alum has been cast on the HBO Max limited series The Staircase based on the Michael Peterson criminal case. Turner will play Margaret Ratliff, one of Peterson’s adopted daughters. Turner joins a cast full of big names, including Colin Firth as Peterson, Toni Collette, Juliette Binoche, Rosemarie DeWitt and Parker Posey. The Staircase will actually be Turner's second HBO Max series. Last year, she signed on to voice William and Kate's daughter Princess Charlotte on the animated British Royal family series The Prince. This will be Turner's second live-action series since Game of Thrones ended in 2019. She previously starred in the Quibi's Survive.
