Cat Among the Pigeons - S11-E2
Corrected entry: At 50':21" running time, there is a sudden flash on the actress's left eye, lasting only for a fraction of a second, seemingly from a camera flash or some other lighting equipment. (00:50:21)
Agatha Christie's Poirot (1989)
1 corrected entry in season 11
Starring: David Suchet, Hugh Fraser, Philip Jackson, Pauline Moran
The Adventure of the Egyptian Tomb - S5-E1
Factual error: In the scene after Poirot pretends to be poisoned, a person folds the modern flag of the Arab Republic of Egypt instead the flag of the Kingdom of Egypt as it was at that time.
The Tragedy at Marsdon Manor - S3-E6
Samuel Naughton: Was the accomodation all right?
Hercule Poirot: No, monsieur Naughton. The accomodation was all wrong.
Samuel Naughton: Oh...
Hercule Poirot: The duck-feather pillows. It feels as if the duck are still in them. (00:14:50)
Trivia: Poirot in the ship's lounge is reading the actual May 1st 1935 issue of Bystander (recognizable by the cover and with the correct page order, does not seem to be a simple movie prop), roughly consistent with the time frame of the first season and a contest taking place on the 14th. (00:07:50)
The Murder of Roger Ackroyd - S7-E1
Question: The doctor (James) put on a Dictaphone to make the suggestion that Roger Ackroyd was alive at 21:30 hrs. But how could he know that someone (Paton) would pass the door of Ackroyd's study at precisely that moment?
Correction: This is just her eye reflecting the off-screen light. At one point, her head and eye movements catch a particularly bright highlight, which is exaggerated by the diffusion filter they are using. If it was a flash from the lighting equipment, you would see it in the lighting of the scene. (Not to mention, why would they be flashing a light in the middle of a shot?)
