Continuity mistake: When Mr. Hardman is interviewed by Poirot, he states "I'm not a theatrical agent," while gesturing with his right hand. The angle changes to show Mr. Hardman from the front, and both his arms are suddenly on the armrests of his chair.

Continuity mistake: When Poirot and Mr. Ratchett first meet in the restaurant car, Poirot has to correct Ratchett's pronunciation of his name. Poirot then points with his right hand toward Ratchett, but when it cuts to a close-up of Poirot, both his hands are on the table. The angle changes back, and Poirot's hand is once again lifted.

Continuity mistake: In one of the flashback scenes, as the drugs start working on Mr. Ratchett, in a close-up he is holding the last anonymous letter in both hands. Ratchett then removes his glasses with his right hand, and places that hand on his forehead. Back to a close-up of the letter and the letter is in both hands, but when it cuts he is holding the letter with only his left hand again.
