First Trailer For HBO’s True Crime Limited Series THE STAIRCASE Starring Colin Firth and Toni Collette

HBO has released the first trailer for their upcoming limited series adaptation of the true crime story The Staircase, starring Academy Award-winner Colin Firth (The King’s Speech, Kingsman) and Academy Award-nominee Toni Collette (The Sixth Sense, Unbelievable). The story is based on the true case in which Kathleen Peterson was found at the bottom of the staircase in her home in a pool of blood.

Her husband, Michael Peterson, made the discovery and called 911, but was then accused of her murder. Many wild theories were tested in this case (including one of a murderous owl), and many scandalous facts came out about Michael’s life, but amateur sleuths have still not been able to come to a consensus on how this whole thing went down.

The two talented stars are joined in the cast by Michael Stuhlbarg, Juliette Binoche, Dane DeHaan, Olivia DeJonge, Rosemarie DeWitt, Tim Guinee, Patrick Schwarzenegger, Sophie Turner, Vincent Vermignon, Odessa Young, and Parker Posey.

The Staircase was created by Antonio Campos (The Devil All the Time), and written and executive produced by Campos and Maggie Cohn (American Crime Story), who both serve as showrunners. Campos also directed six episodes of the series, with Leigh Janiak (Fear Street) directing the remaining two. The first three episodes of The Staircase will debut on HBO and HBO Max on May 5, 2022, and the remaining five will debut each week through June 9, 2022.
