‘Greatest Detective in the World' Returning in Major New TV Series
One of the most famous detectives in literary history is officially heading back to television.
According to a new report from Deadline, the BBC is developing a major new television adaptation centered on Hercule Poirot, the legendary Agatha Christie detective who once famously described himself as "the greatest detective in the world" in the 1928 novel The Mystery of the Blue Train.
Sources told the outlet that the project sparked a competitive bidding situation involving multiple networks and streamers before ultimately landing at the BBC. The broadcaster reportedly made a major commitment to the series, which could potentially run for up to three seasons. Season 1 is expected to premiere sometime in the second half of 2027.
The reboot is reportedly being developed by Mammoth Screen, the production company behind several previous Agatha Christie adaptations, including And Then There Were None and Murder Is Easy. Mammoth founder Damien Timmer also previously executive-produced episodes of Poirot, the long-running ITV adaptation starring David Suchet.
Deadline reported that writer Benji Walters is adapting the project, though plot details are currently being kept under wraps. The series is expected to film in Liverpool and north-west England later this summer.
Casting for Poirot himself is also reportedly underway, a role likely to generate enormous interest given the detective's legendary status in popular culture. Over the decades, Poirot has been portrayed by actors including Alfred Molina, John Malkovich, Peter Ustinov and Suchet, whose version remains the definitive Poirot for many viewers.
Poirot first appeared in the 1920 novel The Mysterious Affair at Styles and eventually featured in 33 novels and 51 short stories over more than five decades.
The meticulous Belgian detective became famous for his waxed moustache, immaculate appearance and reliance on what he called his "little grey cells" to solve crimes through psychology and logic rather than brute force.
Poirot's influence on detective fiction has remained enormous for more than a century. Christie's final Poirot novel, Curtain: Poirot's Last Case, published just a few months before Christie died in early 1976, became so culturally significant that the New York Times famously published an obituary for the fictional detective on its front page after the character's death. He is still the only fictional character to ever have an obituary published by the renowned newspaper.
The Christie universe has seen a major resurgence in recent years. Netflix recently released Seven Dials, while BritBox is currently developing a new adaptation of Agatha Christie's Tommy & Tuppence. Kenneth Branagh also recently revived Poirot on the big screen with Murder on the Orient Express, Death on the Nile and A Haunting in Venice.
