Sophie Turner is heading back to HBO for ‘The Staircase’ set to stream on HBO Max.
The Emmy nominee will join previously announced cast members Colin Firth, Toni Collette, Parker Posey, Juliette Binochie and Rosemarie DeWitt.
The developing series will follow the life of American Novelist Michael Peterson (played by Firth), who was accused of murdering his second wife Kathleen (played by Collette) in 2001. Per Peterson’s own account, Kathleen died after falling off the stairs at their home, but Police investigations claimed otherwise resulting in conviction and a 16-year judicial battle.
Turner is expected to play Margaret Ratliff, one of Peterson’s adopted daughters, who believed her father was innocent of the charge.
‘The Staircase’ will be based on the docuseries by Jean-Xavier de Lestrade of the same name as well as published books and reports surrounding the case. Showrunners Antonio Campos and Maggie Cohn are writing and executive producing with Campos directing six of the eight episodes of the show.
Turner’s acting resume includes the megahit drama series ‘Game of Thrones’, which concluded a little over a year ago at HBO. She has also featured in the ‘X-Men’ film franchise starring in the parts ‘X-Men: Apocalypse’ and ‘X-Men: Dark Phoenix’.
She is repped by CAA and Independent Talent Group.
