Continuity mistake: This film's set in the 50s, but the actors use 20 Austrian Schilling bank notes, which were only issued in the mid 1970s.
Continuity mistake: When Hadrian jumps the mustang over the upturned car, the film slows down to show the jump in slow motion. When the car lands, it hits so hard the car spins around and ends up facing the cars it jumped. The scene is then repeated at normal speed, but just as the car would be shown spinning out, a shot of the car driving away from the accident is shown.
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.Twotall
Continuity mistake: There are a number of scenes (stable house, car, hotel) showing Claudia wearing a green harness dress. It is quite obvious that she is not wearing a brassiere in all of those scenes. In the hotel room, where Foxy and Claudia meet the judges, Claudia removes the green dress and is now wearing a bra. It would be highly unlikely that she would be putting one on, at the same time she is getting undressed. This was obviously done to cut down on nudity in the film. (00:41:30 - 00:47:45)
