Agatha Christie's Poirot

Triangle at Rhodes - S1-E6

Factual error: Throughout the episode there are sections of dialogue in Greek, which are deliberately left untranslated. The subtitles frequently transcribe the Greek inaccurately. For example, the Greek girl who assists Poirot and Lyall in finding out about the poison says "Elate!" to them, which means "Come!" said to more than one person, but this is transcribed in the subtitles as "Ella!", the form used to a single person. Later on, the girl's grandmother says "Ohi enas Anglos anthras. Mia Anglitha yineka. San esena" ("Not an Englishman. An Englishwoman. Like you"), but this is given in the subtitles as "Ohi enas Anglos anthras, che yenika. Son ethena", which doesn't make sense. (00:40:45)

Triangle at Rhodes - S1-E6

Factual error: Poirot and Lyall speak to people in the street of Rhodes, looking for someone who can tell them about the poison. The people they speak to all shake their heads, but Greeks do not do this to say "no" - they tip their heads back. (00:39:40)

Triangle at Rhodes - S1-E6

Factual error: At the end of the report on the findings of the crime scene, the "Italian" inspector tells to his subordinates what literally would translate as "Removes this meddler from here, no more access to the prisoner, that you understand?", which is just wrong in accent, cadence and construct. (00:36:30)

Murder on the Links - S6-E3

Factual error: Poirot gets on the train to London. The engine has an SNCF plaque on it. The video then cuts to the 1936 cycle race. The BCNF was not formed until 1938.

The Tragedy at Marsdon Manor - S3-E6

Factual error: It is well established that the episode takes place in 1935 (Nairobi Daily Press dated Saturday July 27 1935, the poster in town advertises the meeting for "Today, Wednesday September 4th", day of the week consistent with the year), but Poirot and Hastings are stopped on their way to the train station by a Wolseley Series II - 14/56, a model that entered production in mid 1936. (00:17:00)

The Double Clue - S3-E7

Factual error: At the party, Marcus Hardman tells Bernard that the Countess recently arrived from Russia, and she describes herself as being in exile. Which made sense in the source material, set right after the Russian Revolution, but less sense in this adaptation, set in the mid 1930s. If she stayed in Russia that long, she would have spent 15-20 years with zero privileges from her rank at that point, and nothing from her old wealth, seized by the communist government.

The Double Clue - S3-E7

Factual error: Poirot is visiting an art exhibition with the Countess, and expresses his admiration for a painting by Marc Chagall. Amazingly enough, that painting is "Les Plumes en Fleurs", something Chagall will create in 1943, years after the time when this pre-WW2 episode takes place. (00:24:50)

The Double Clue - S3-E7

Factual error: Attention to detail in props is always extremely high in this series, and tubular flashlights have been in circulation since the beginning of the century. However the one that the supposed burglar is holding as they make their way through the top floor of the villa looks perfectly modern and unlike any model compatible with the 30s. (00:10:20)

The Double Clue - S3-E7

Factual error: Hastings and Miss Lemon decide to investigate on their own. In the outside view of the first suspect they go question, a large contrail is visible on the left of his building (contrails were not a complete impossibility in the 30s, but it's rather odd to randomly see one in an establishing shot for this timeframe). (00:22:40)

Wasps' Nest - S3-E5

Factual error: When we see the cover of Vogue magazine where Molly Deane appears, the recreation is not bad (the lettering used is not a classic Vogue one but something very similar was used for instance in August of the same year as portrayed), but the bar at the bottom gets the date wrong, putting it down as September 10th 1935, when Vogue always had 1st and 15th of the month as date of the release, no matter the day of the week. Also, it completely omits for instance the price. Would be a pretty difficult magazine to sell without that, real Vogue covers have that detail prominently displayed. (00:03:20)

The Plymouth Express - S3-E4

Factual error: At the end of the episode, Hastings is reading a sports newspaper. The episode is set in 1935, and a weekend, but what he is reading there announces the jockey Billy Parvin substituting Fawcus riding Galdennis, and Golden Miller and the ticket for the sweeps, making the newspaper a March of 1933 one. (00:50:55)

The Plymouth Express - S3-E4

Factual error: Florence Carrington is killed on the train while she is leaving London for the weekend. When Poirot and Hastings examine the newspapers she could have been looking the day she was killed, the headline of "The evening news" in Poirot's hand announces the world record set by Malcolm Campbell at Bonneville Salt Flats in Utah, which happened on 3 September 1935, a Tuesday. (00:27:40)

The Murder of Roger Ackroyd - S7-E1

Factual error: A few drops of acid are dropped on a penny and the liquid bubbles (colorless liquid) as the acid eats its way through the penny. The penny is mostly copper. Any acid that can react with a copper will also produce a bright green to bright blue solution of dissolved copper, which is not the color seen. (00:05:20)

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Not necessarily. It depends on the acid and its strength. A weak acid may only oxidise copper to a monovalent state (Copper (I)) (which is colourless) rather than its divalent (Copper (II)) state which produces the blue solution.

Andy Benham Premium member

The acid must be an oxidizing acid. This plus being done in the open air would result in any copper (I) formed quickly being oxidized to copper (II). Copper (I) is extremely unstable under the conditions shown.

Dumb Witness - S6-E4

Factual error: Spoiler. Police Sergeant Keeley tells Poirot that Doctor Grainger died of carbon monoxide poisoning. The killer turned the natural gas in the bedroom and did not light the heater. This would result in the room filling with natural gas, not carbon monoxide. (01:17:30)

The Yellow Iris - S5-E3

Factual error: Poirot smells and very carefully tastes a drink and says, "Potassium cyanide." It is impossible to distinguish between potassium cyanide and sodium cyanide (the other common cyanide) by this method. In addition, there are another less common cyanides that would smell and taste the same as potassium cyanide. (00:16:01)

The Underdog - S5-E2

Factual error: Lily looks over part of the procedure for the manufacture of Astroprene. There are several problems with the chemical structures shown in step two of the procedure. This step appears to be a simple acid catalyzed rearrangement of the molecule shown. The procedure should begin with a C inside the hexagonal ring and end with the C outside the ring with no other changes. The errors include, among other things, a carbon atom at the lower left of the ring with two lines (bonds) to it. The C should have four bonds (lines), the two shown plus two to hydrogen atoms (H). The bonds to H may be condensed so the C will look something like -CH2 - (the 2 would be a subscript). (00:10:30)

The Million Dollar Bond Robbery - S3-E3

Factual error: The stock footage of the Queen Mary coming back from the US and docking in Southampton is not in black and white, and it certainly is more recent. The crowd wears colorful clothes, no hats, neon lights are used for the building illumination, and the cars parked are of modern design. It's a post-WW2 world, not 1936. (00:38:40)

The Million Dollar Bond Robbery - S3-E3

Factual error: As the title of the episode says, it's a million dollar robbery, in bonds. Problem is, as seen when the bag is loaded, the million is in 50 dollar bonds, which was the lowest single denomination for Liberty Bonds. 20,000 big bond notes would never fit in that bag, and would weigh a lot! Funny mistake, considering that the reality of 'weight' of a sum is a problem in many movies dealing with regular dollar bills, but bonds would have much fewer limitations as for the denomination of a single note (could have been a pile of bonds worth $10,000 or $5,000). (00:19:50)

How Does Your Garden Grow? - S3-E2

Factual error: Poirot and Miss Lemon go to the riding school to meet the solicitor of the deceased. Parked in the road right as the camera pans, and featured for a few seconds, is a car Morris Eight series II, a 1938 model while the episode (as made abundantly clear by the fair invite and banner) is set in 1935. (00:28:25)

The Mysterious Affair at Styles - S3-E1

Plot hole: Can't fault this massive plot hole to the adaptation, but to the source material; the culprit (forgetting the stupidity of writing an incriminating letter detailing the plan to murder someone, and put it in a desk he shares with her) since there are people outside the room that are about to enter, tears the letter in 3 neat vertical strips, rolls them, puts them in the vase on the mantlepiece, and then opens the side door to slip away...instead of simply pocketing the letter and going through that same door. Nobody was going to search him or anything and could have burned it, torn it into confetti, anything, later. It takes way way longer to do what he did, which needed him to stay there in the room increasing the chances of being found out. And of course he and his accomplice do not retrieve the letter after.
