Murder in Three Acts is a British-American made-for-television mystery film of 1986 produced by Warner Bros. Television, featuring Peter Ustinov as Agatha Christie's detective Hercule Poirot. Directed by Gary Nelson,[1] it co-starred Jonathan Cecil as Hastings, Tony Curtis, and Emma Samms.
The film is based on Christie's book Three Act Tragedy (1934), published in the US under the title Murder in Three Acts. It was Ustinov's third and last portrayal of Poirot on television, and sixth overall including the feature films that preceded the TV movies.
In 1974, Murder on the Orient Express was released, starring Albert Finney as Poirot. As Finney was unable to reprise his role for the sequel, Death on the Nile (1978), Peter Ustinov was cast in the part and reprised it for Evil under the Sun in 1982, Thirteen at Dinner (1985), Dead Man's Folly, and Murder in Three Acts (1986).[2]
Another screen adaptation in 1988, Appointment with Death, was Ustinov's last portrayal of the Belgian detective.[3]
Poirot joins his assistant Hastings in Acapulco, Mexico, where Hastings is staying. They go to a party at which the other guests include the writer Janet Crisp, the American actor Charles Cartwright, a clergyman called Babbington, Daisy Eastman and her daughter Egg, Dr Strange, and Ricardo Montoya. Babbington dies of poisoning, then Strange is poisoned, too, and Poirot hunts the murderer.
The main change from the original story is the relocation of the action from London to Acapulco. In the book, Poirot's assistant is Satterthwaite, replacing Hastings, but in the film Hastings is reinstated in his usual role. Christie's English theatrical actor Sir Charles Cartwright turns into Charles Cartwright, an American movie star.
A version made in 2010 in the Poirot series starring David Suchet restored the title "Three Act Tragedy", as well as reinstating Sir Charles Cartwright (played by Martin Shaw) as an English stage actor.
