Agatha Christie's Poirot: Murder on the Orient Express (2010)

In the 2010 adaptation, Dr Constantine is played by Samuel West. He is a Greek obstetrician who is visiting Ankara and on his way back to the U.S. He is the one who finds the train conductor's button on the floor while he and Poirot are interviewing Mrs Hubbard in her compartment.

Poirot suggests that Dr Constantine was Mrs Armstrong's obstetrician, and had seen the Armstrong family suffer as a result of Daisy's kidnap and murder. This is not mentioned in the novel.

In the reconstruction of the murder during the denouement, Dr Constantine is the ninth person to stab Ratchett, after receiving the knife from Masterman. He then hands the knife to Pierre Michel. This is different from the novel, where Dr Constantine did not take part in the stabbing.
