- Hercule is a six‑hour series written by Benji Walters that will dramatize three of Poirot’s early cases and introduce characters who become his allies and a noted nemesis.
- Jonny Campbell, Chanya Button and Alrick Riley will split directing duties, Charlie Palmer is series producer, and Mammoth Screen and Agatha Christie Limited are producing for BBC One/iPlayer and BritBox.
