Common mistakes

Factual error: Many early mystery movies do not consider fingerprint evidence, even though such evidence has been accepted in US courts since 1911 and in the UK since 1858.

Dead Man Walking - S4-E16

Factual error: The inspector is suffering from thallium poisoning. However, everyone is using various radiation detection methods to detect the thallium. Natural thallium is not radioactive. Of the artificial thallium, the only with a half-life long enough to last long enough to pose a problem is too weakly radioactive to be a significant hazard.

Noman

Factual error: The trip goes back 65 million years. This is the late Cretaceous period. The Allosaurus was a Jurassic period dinosaur, which became extinct before the beginning of the Cretaceous period. Granted, the Allosaurus was probably the most powerful predator of its time, the events in this movie take place long after the time of the Allosaurus.

Count Dracula (1970)

Continuity mistake: Professor van Helsing and Doctor Seward enter the Harkers' bedroom. A few seconds later, they enter the bedroom again. (00:52:00)

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)

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

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)

Suggested correction: Surely it was coal gas at that time, before we all converted to natural gas?

The product of coal gas is still methane, which is CH4. It may contain tiny volumes of CO but the gas asphyxiation would still have come from methane, not carbon monoxide.

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)

Red River (1948)

Trivia: This was Harry Carey Sr.'s last film. It was also the only film to have both Harry Carey Sr. And his son, Harry Carey Jr., star. They did not have any scenes together.

She (1935)

Character mistake: A priest is holding a globe with a fire to light the globes carried by others. There are two lines with globes approaching the man with the lit globe. The first person in the line from the right has trouble lighting their globe. She starts to return for a second try, but apparently thinks better of it and continues on with the unlit globe.

She (1935)

Audio problem: A native descends a rope to beat on a drum and signal those inside to open the door. As the native beats on the drum, his actions and the drum sounds become further and further out of synchronization.

Episode #1.1 - S1-E1

Factual error: There is a view of the night sky in southern Africa. However, both the Big and Little Dippers (along with Polaris) are visible. In general, these constellations are not visible in the southern hemisphere, and where they are (North of 1° South latitude) they are very close to the horizon. The Big Dipper (Ursa Major) is to the left of the screen and Polaris (part of the Little Dipper = Ursa Minor) in near the top-center. This occurs shortly after the lion cub scene. (00:44:00)

Noman

Continuity mistake: The adventurers are met by a ship with a single sail that has a triangular symbol on it. When they first see the ship the sail is unfurled and shortly afterwards it is unfurled again.

Noman

Other mistake: In the opening credits the following is posted "Screenplay based on Rider Haggard's Allan Quartermain" The author's name is usually given as H. Rider Haggard (H. For Henry), and Haggard's hero was named Quatermain (1 "r" not 2). This misspelling of Quatermain appears in many movies.

Noman

Factual error: The movie takes place during or shortly before World War I. At one point, Quatermain and Jessie find a German base. Thus, they are probably in one of the pre-World War I German African colonies (Probably German East Africa or German South West Africa). There is a red, white, and blue French flag flying over the camp instead of a German flag.

Noman

Factual error: Quatermain and Jessie are on the roof of the caboose of the train. The train engineer slams on the brakes because there are elephants on the tracks. Instead of being flung forward as the train slows, Jessie is flung towards the rear.

Noman

Audio problem: When Quatermain and Jesse are fleeing in a stolen truck, they are being chased by people in other vehicles. Even though all the streets are dirt, there are numerous times when the tires of all the vehicles squeal.
