The BBC has announced casting for the forthcoming six-part series Hercule from Mammoth Screen and Agatha Christie Limited.

Joining Bluemel are Henry Ashton (A Knight of the Seven Kingdoms, A Good Girl's Guide to Murder), James D'Arcy (Oppenheimer, Constellations), Calvin Demba (Supacell, Life), Phil Dunning (Smoggie Queens, Am I Being Unreasonable?), Jack Gleeson (House of Guinness, In the Land of the Saints and Sinners), Tamsin Greig (Riot Women, Friday Night Dinner), James Nesbitt (Cold Feet, Run Away), Guy Remmers (The Buccaneers, Lessons), Rebecca Rittenhouse (His & Hers, Maggie) and Mawaan Rizwan (Juice, The Split Up).

They are set to join the new adaptation chronicling the story of the world’s greatest detective – and how he became it, which is due to commence filming soon, primarily in Liverpool.

The series is an intimate study of Hercule Poirot the man and an epic portrait of Britain between the wars. The series will centre around three of Christie’s early stories, while also introducing Hercule Poirot to future friends and allies and one particular nemesis…
