Netflix has long been the go-to destination for true-crime documentaries, from the explosive Making a Murderer to the chilling The Staircase docuseries. But now, the streamer is reaping the rewards of a different kind of crime story: the dramatized version of The Staircase, which originally aired on HBO in 2022. As of April 2026, the Colin Firth-led series has stormed into Netflix's Top 10, proving that audiences can't get enough of this twisted tale of guilt, innocence, and the media circus that surrounded it.
From Documentary to Drama: The Journey of 'The Staircase'
The original The Staircase docuseries, directed by Jean-Xavier de Lestrade, first aired in 2004 and followed the investigation and trial of Michael Peterson, a novelist accused of murdering his wife Kathleen. Netflix later acquired the series and added new episodes, making it one of the platform's most popular true-crime offerings. The case sparked endless debate: Did Peterson push his wife down the stairs, or was it a tragic accident?
HBO saw an opportunity to bring the story to a new audience with a scripted adaptation. Released in 2022, The Staircase stars Colin Firth as Michael Peterson and Toni Collette as Kathleen Peterson. The series doesn't just reenact the crime and trial; it also delves into the making of the original documentary, blurring the lines between reality and dramatization. Now, four years later, that HBO series has found a second life on Netflix, where it's climbing the charts alongside other true-crime hits.
Why This Version Stands Out
What makes the dramatized The Staircase so compelling is its star-studded cast and its meta-narrative. In addition to Firth and Collette, the ensemble includes Sophie Turner, Patrick Schwarzenegger, Michael Stuhlbarg, Dane DeHaan, Odessa Young, Parker Posey, Olivia DeJonge, and Rosemarie DeWitt. Each actor brings depth to the real-life figures caught up in the Peterson saga, from the defense team to the prosecutors and the documentary crew.
The series also benefits from its layered storytelling. It doesn't just ask whether Peterson is guilty; it questions the ethics of documentary filmmaking and the role of media in shaping public opinion. For fans of the best thriller TV shows of the 2010s, this is a must-watch that continues the tradition of gripping, thought-provoking crime drama.
Netflix's True-Crime Dominance Continues
Netflix's investment in true crime has paid off handsomely over the years. After the massive success of Making a Murderer in 2015, the streamer expanded its slate to include titles like The Staircase docuseries, Tiger King, and more. Now, by adding HBO's dramatized version, Netflix is tapping into the same audience that made those earlier shows hits. The platform currently boasts a robust lineup of true-crime content, including newer titles like Hulk Hogan: Real American and Trust Me: The False Prophet.
For those who prefer their true crime with a side of Hollywood glamour, the dramatized The Staircase is the perfect binge. It's a reminder that some stories are too strange—and too compelling—to be told just once. If you're looking for something to watch this weekend, this is a strong contender, much like Netflix's 'The Letter for the King' for fantasy fans.
