Factual error: Throughout the series, traffic in Pakistan is depicted driving on the right. In Pakistan, traffic drives on the left.
Factual error: At the end of the episode, they say the Bible said he lived to be 110 years old. The Bible says 70.
Factual error: "Underground" is set in 1857 Georgia, yet the padded baseball glove August Pullman gives to his son is of a type used during the early 20th century. Before 1883 when padded gloves were first manufactured, gloves were either not used by baseball players or railroad brakeman's gloves were used.
Audio problem: They went to an investigator to let him listen to the audio. The audio with the woman screaming and the gasp, the gasp was Zak, not another apparition.
Factual error: In season 1, there is an Egyptian woman wearing ornate jewellery around her head. Unfortunately, at least 3 components are old UK currency coins from the latter half of the 20th century. Clearly visible are copper 2p pieces and one old silver 10p coin. (00:38:40)
Factual error: Johann Eck is dressed as a cardinal and Albrecht von Brandenburg addresses him as "Your Eminence" and kisses his ring. In reality, Eck was not a cardinal. Albrecht, however, was. It should be Eck showing deference to him, not vice versa. Albrecht was also only thirty, half the age of the actor playing him.
Episode #1.1 - S1-E1
Character mistake: In the opening minutes of the first episode, as the Erasmus is struggling through a storm, Blackthorne is told that the boatswain is dead. He checks the corpse and then says, "Get the body aloft," which would entail carrying the deceased up the mast. The correct order would be "Get the body topside."
Factual error: Pierre Bezukhov's spectacles are of the type with nose pads, which were not invented until the late 1920's.
Factual error: The Mitanni king and his son are depicted as black Africans. The Mitanni originated in the modern Iran/Iraq area, or possibly as far east as India, but certainly nowhere near Africa. They were definitely not black Africans.
Continuity mistake: When the princess moves between rooms, the door in the first room is left well open, but when the shot changes to the second room, the first door is almost closed. (00:05:40)
Deliverance - S1-E3
Factual error: The crosses marking the graves of British soldiers outside the hospital abbreviate Private as the American "Pvt" rather than the British "Pte."
Factual error: Both Inspector Shaw and Chief Inspector Bailie wear their medal ribbons in the wrong order. The Golden Jubilee Medal is worn first, followed by the Diamond Jubilee Medal, followed by (for Bailie) the Long Service and Good Conduct Medal.
Episode #5.7 - S5-E7
Other mistake: Two actors are standing on an ancient muddy track which shows the tyre prints of a modern vehicle, made probably by the 4WD camera car. (00:09:00 - 00:10:00)
Factual error: Gordon Liddy is in federal prison and in solitary confinement, and he is still wearing his gold wedding band. (00:29:36)
Up the Crick Without a Piddle - S7-E4
Visible crew/equipment: While Madam Fanny is rehearsing at the piano, behind her in the background, a woman comes down the stairs. It is not a waitress, and Rene and Edith are still in London.
Factual error: The Merchant Navy rank insignia is very poorly researched. Each officer seems to have a different style of insignia, despite working for the same company and they incorrectly wear rank insignia on the shoulders of their blue uniforms as well as the cuffs. The main character, Junior Third Officer Mortimer, wears a bizarre mix of insignia, apparently consisting of a Royal Navy petty officer's sleeve badge, a Royal Navy chief petty officer's cuff buttons, and a rank badge of three inverted chevrons on his shoulder boards that doesn't seem to resemble anything from reality. In reality, he should simply wear a single cuff ring (or shoulder bar in white uniform).
Factual error: Sir John Franklin, Francis Crozier and James Fitzjames all wear a crown over an anchor on their epaulettes, the rank badge for a captain with over three years in rank. This is correct for Franklin and Crozier, but Fitzjames only held the rank of commander, and should therefore only be wearing an anchor on his epaulettes.
Factual error: In a scene set in March 1968, after Tammy Wynette finishes recording "D-I-V-O-R-C-E," George Richey introduces himself to George Jones as the musical director of "Hee Haw." John Aylesworth and Frank Peppiatt created the "Hee Haw" series in 1969.
Factual error: At the picnic, a woman says she is going to New York by train. It is 1828. Railway passenger service in the United States did not begin until 1830 and it would not be possible to travel from North Carolina to New York until some years after that.
Revealing mistake: The set where Augustus visits Agrippa on Lesbos for reconciliation is the same set where Augustus already was before - he was there earlier, reading the news of Marcellus' death while he was away from Rome to visit the Eastern provinces. But as stated, he had not visited Lesbos at all, because he and Agrippa had temporarily fallen out. (00:39:30 - 00:41:30)
