David Suchet will return as Poirot for the 65th time
Award-winning actress Dame Eileen Atkins and Barbara Hershey will star in a new TV adaption of Agatha Christie's Murder On The Orient Express.
David Suchet, who has played Hercule Poirot for 21 years, will return as the moustachioed Belgian detective.
Producer Karen Thrussell said the story is the "most ingenious and best loved Agatha Christie title of all time".
The adaption will be filmed on location in London and Malta. ITV has not yet announced when it will be broadcast.
The story follows Poirot's fateful journey from Istanbul to Belgrade, where he is called upon to solve the murder of ruthless American businessman Samuel Ratchett.
Samuel West and Hugh Bonneville have also been cast to star in the adaption.
The novel, which was first published in 1934, was made into a film in 1974 with Albert Finney, Lauren Bacall and Sean Connery.
Suchet has just finished making four other forthcoming Poirot films for ITV, including Appointment with Death, The Clocks, Three Act Tragedy and Hallowe'en Party.
