The American actor controversially revealed his version of the French investigator would be talking with an English accent.
Malkovich told the Radio Times: “In our version, Poirot has lived in England for 20 years and has made a very long and laborious effort not to seem too much like a foreigner and to speak English like an Englishman.”
In the adaption, written by Bafta nominated writer Sarah Phelps, Malkovich is joined by Harry Potter star Rupert Grint as Inspector Crome, The Walking Dead’s Tara Fitzgerald as Lady Hermione Clarke, and Broadchurch star Andrew Buchan as Franklin Clarke.
Also appearing are Eamon Farren as Cust, Shirley Henderson as Rose Marbury, Jack Farthing as Donald Fraser, Bronwyn James in the role of Megan and Freya Mavor as Thora Grey.
The story, set is the 1930s—a time when the nation is dangerously divided and suspicion and hatred are on the rise—sees Poirot is tasked with tracking down a serial killer known only as ABC.
