The Trailer for HBO's 'The Staircase' Immerses Colin Firth and Toni Collette in a True-Crime Tragedy

Whenever a new true-crime tale arrives, audiences fall into three camps: those who are well aware of all of the case's ups and downs, folks who remember the headlines but are vague on the details, and others that come to the whole saga and its specifics brand new. With The Staircase, it's highly likely that more viewers will fall into the first two categories. The eight-part HBO miniseries isn't just based on an IRL crime, after all, but also on a French documentary series of the same name.

For those learning about the story afresh, it all started in 2001, when novelist Michael Peterson reported the death of his wife Kathleen. He said that she had fallen down the stairs at their North Carolina home — yes, hence the name — but the authorities weren't convinced. Given that occurred more than two decades ago, how it all turned out is now a matter of history. So, you'll either know it and be intrigued to see how it plays out on-screen with Colin Firth (Supernova, 1917) and Australian star Toni Collette (Nightmare Alley, Dream Horse) as the central couple, or you'll want to discover the intricacies for yourself while watching.

Plunging famous faces into a twisty miniseries is firmly HBO's approach of late, with The Staircase following everything from Big Little Lies and The Undoing to Mare of Easttown. Joining the high-profile duo when the US network's latest hits Binge in Australia and Neon in New Zealand from Thursday, May 5: an all-star cast that also features Juliette Binoche (How to Be a Good Wife), Michael Stuhlbarg (Call Me By Your Name), Parker Posey (Lost in Space) and Sophie Turner (Game of Thrones), as well Rosemarie DeWitt (Little Fires Everywhere), Dane Dehaan (Lisey's Story), Patrick Schwarzenegger (Moxie), and Aussie actors Olivia DeJonge (Better Watch Out) and Odessa Young (Shirley).

There are clearly plenty of moving parts to this narrative, which comes to TV courtesy of writer/director Antonio Campos (The Devil All the Time, The Sinner). As the just-dropped full trailer shows, there's plenty of drama as well. That's true both before and after the Peterson family find themselves immersed in a heartwrenching tragedy. Indeed, the sneak peek starts with happy times — with saying cheers to happy folks sat around the dinner table, in fact — but that isn't how it ends.

Given that it's hitting screens 18 years after the original The Staircase, this dramatised version even mentions the film crew eager to start recording the details after Kathleen's death. So, when it starts airing in May — dropping three episodes at once to kick things off, then going weekly — the show will cover a well-known true-crime case as well as the just-as-well-known TV show that's already been made about it.

The Staircase will start streaming via Binge in Australia and Neon in New Zealand from Thursday, May 5.
