Parker Posey Joins Colin Firth and Toni Collette in HBO Max Crime Show 'The Staircase'

Juliette Binoche and Rosemarie DeWitt co-star in the limited series, which hails from director Antonio Campos.
Indie queen Parkey Posey has signed on to join the cast of HBO Max’s true-crime series The Staircase starring Colin Firth and Toni Collette.
Director Antonio Campos is putting together quite a cast for this one, as the eight-episode limited series will also co-star Juliette Binoche and Rosemarie DeWitt. That’s four formidable actresses in a single show that’s anchored by an Oscar winner. Not too shabby if I do say so myself.
The Staircase is based on the true-crime docuseries of the same name, as well as various books and reports on the case. It tells the story of American novelist Michael Peterson (Firth), his sprawling North Carolina family, and the suspicious death of his wife, Kathleen Peterson (Collette), a corporate executive and mother/stepmother of five.
