Production In late May 2026, it was reported that a new television adaptation of the Hercule Poirot novels was in development from Mammoth Screen, the production company responsible for ITV's Endeavour, Victoria and McDonald & Dodds, with the BBC set as the broadcaster. Executive producer Damien Timmer, who had previously worked on the long-running Agatha Christie's Poirot, joined the new programme as an executive producer, with the series to be scripted by Benji Walters. On June 8, the series was confirmed to be titled Hercule, with Edward Bluemel having won the lead role.

Jonny Campbell joined the project to executive produce and direct the first two episodes. Charlie Palmer was also named as the primary producer. Chanya Button and Alrick Riley were later confirmed to direct the remaining blocks. The series will consist of six 60 minute episodes covering three of the novels.

Ten further cast members were announced in August, including Jack Gleeson, James D'Arcy, Tamsin Grieg, James Nesbitt and Mawaan Rizwan. Production began later that month, with filming largely taking place in Liverpool and England's north-west area, including Bolton. In October, another ten cast additions were announced, including Omari Douglas, Ralf Little, Katherine Parkinson and Toby Stephens.

A commitment has reached for a potential run of at least three series.

Lord Edgware Dies will be the first book adapted for the series, followed by Peril at End House.

Release Hercule is expected to air on BBC One and BBC iPlayer in the latter end of 2027. BritBox will distribute the series in North America and Canada, while Fifth Season will handle the international release.
