The trio will rejoin David Suchet as Hercule Poirot in one of the final adaptations of Agatha Christie’s novels featuring the famous Belgium detective. The adaptation of The Big Four is being written by Mark Gatiss and Ian Hallard. Gatiss has previously penned the Poirot episodes Hallowe’en Party and Cat Amongst the Pigeons and appeared in Appointment with Death and the Marple episode Murder at the Vicarage.
Hugh Fraser and Pauline Moran will reprise their roles of Captain Hastings and Miss Lemon for the first time on-screen since the 2001 adaptation Evil Under the Sun. Phillip Jackson’s last appearance as Chief Inspector Japp was also last seen in Evil Under the Sun. Following the adaptation of the novel the Poirot series moved to solo outings for David Suchet with occasionally appearances from Zoe Wanamaker as the novelist Ariadne Oliver.
The Big Four will also star Sarah Parish, Michael Culkin, James Carroll Jordan, Patricia Hodge, Nicholas Burns and Simon Lowe. The Big Four will make up part of Poirot’s last season along with the stories Elephants Can Remember, The Labours of Hercule Poirot and Curtain: Poirot’s Case. According to several reports The Labours of Hercule Poirot will also feature Fraser, Moran and Jackson in their respective roles.
