HBO Max has released a teaser trailer from the upcoming eight-episode Max Original limited series, THE STAIRCASE, starring Colin Firth and Toni Collette, debuting this spring. The limited series is written and executive produced by showrunners Antonio Campos and Maggie Cohn.

Campos also directs six of the eight episodes.

Based on a true story, THE STAIRCASE explores the life of Michael Peterson, his sprawling North Carolina family, and the suspicious death of his wife, Kathleen Peterson.

Starring alongside Colin Firth and Toni Collette are Michael Stuhlbarg, Juliette Binoche, Dane DeHaan, Olivia DeJonge, Rosemarie DeWitt, Tim Guinee, Patrick Schwarzenegger, Sophie Turner, Vincent Vermignon, Odessa Young and Parker Posey.

Sarah Aubrey (Head of Original Content, HBO Max) said, “It is a thrill to collaborate with Antonio Campos, Maggie Cohn and Annapurna Television for the exploration of this true-life story that’s rife with dramatic revelations. With the enormously talented Colin Firth at the center of this adaptation, the story of THE STAIRCASE will continue to captivate audiences with every bizarre twist and turn.

”

And Antonio Campos also made a comment, “This has been a project I have been working on in one way or another since 2008. It’s been a long and winding road, but well worth the wait to be able to find partners like HBO Max, Annapurna, co-showrunner Maggie Cohn and the incredible Colin Firth to dramatize such a complex true-life story.”

The limited series is co-produced by Annapurna Television.
