Factual error: Secretary of State John Hay is depicted issuing the order to "initiate hostilities" against Spain. Unfortunately, at the time we actually went to war with Spain, John Hay was not the Secretary of State. That position was held by William. R. Day. Hay did not become SofS until September of 1898, after most hostilities had ended.
Factual error: When the agent searches for Abu Ahmed in Peshawar, Pakistan, in one scene he gets out of his car, and a shop named Bhatia sons appear in the background, a company based in Delhi, India. In the next scene he is walking down a market, where a sign board of Jaggi sweets, (existing in Punjab, India) is seen, with words written in Hindi (only to be found in India).
Factual error: When the ship is being launched a champagne bottle is smashed against the hull. Harland & Wolff, like many shipbuilders, did not smash champagne bottles against the hull.
Factual error: In an early scene, a character suggests that a man might be awarded an OBE honor if he wins the 1913 US Open. The OBE wasn't established until 1917.
Continuity mistake: The book Geronimo steals from the wagon train is red. When he gives it to his wife it is black.
Continuity mistake: The actress loads her 35mm Praktica camera with Kodak film. That's not really strange, but the film is situated in 1968 around the invasion of the Russians in Prague. The film cassette is clearly visible as having DX coding on one side for setting the film speed automatically. This feature had yet to be invented in 1968, because it was released in the early 80's.
Other mistake: When Anne and Peter are looking at the stars, Anne points to a star and Peter knows what star she's pointing to. It is impossible to point to a star and have someone else know exactly what star you're pointing to. Try it.
Factual error: The movie is supposed to be in the 15th century. In a scene we see a priest, wearing a Jesuit robe. But the Jesuit order was founded in the 16th century. So it's impossible that a priest wearing a Jesuit robe appears there.
Continuity mistake: When the message from Göering arrives in the Führerbunker, the signature jumps from one side of the paper to the other. When we first see the machine printing the words "H. Goering, Reichsfeldmarschall", they are on the left side of the paper, as the officer removes the paper from the printer the signature is to the right.
Factual error: In order to make Polyphem drunk, Ulysses and his men produce 'wine' by treading on grapes. Only thing is: without fermenting the stuff for a few months, all you get is grape juice, which is not even remotely intoxicating.
Continuity mistake: During entire scene with dancing king Herod and his men, shadows on the floor are at different angles from one shot to another. (01:16:15 - 01:19:30)
Deliberate mistake: As the Soviet tank starts rolling, the tank commander obviously uses a hidden step to mount the tank. Soviet T-55/T-62 type tanks did not have steps for mounting by the wheels and axles; to mount a rolling tank using the moving wheels or spinning axles would result in the mounter being immediately crushed and killed.
Other mistake: As Anne is about to be executed for adultery she begins recalling the important events of her life since meeting Henry VIII. She counts each of the wooden stakes numbered "100 Days" and recalls various events involving she and Henry. There should be 10 to account for the 1000 days but there are only nine. (02:13:00)
Factual error: Big Ben is heard to strike in 1804, fifty years before it was built.
Continuity mistake: As Michael leaves after being fired and Chuck returns to the office, the clocks in the newsroom read drastically different times in each shot, even going backward through time at one point.
Factual error: In the ambush-on-the-prison scene, one of the Boers is equipped with a Lee-Enfield CLLE Charger-Loading Rifle. Although the Boers used many captured Lee-Enfield and Lee-Metford rifles, the CLLE's weren't even developed until the Boer War had ended.
