Factual error: On the map behind the colonel during the first scene, Iceland is labelled as being under Nazi control. This is incorrect, as the British were in control of the country during the whole of the war. (00:05:10)
Factual error: The snakes in the King of England's pit are all constrictors. They do not have venom and are too small to see a human as prey, yet they show a man dying from a bite by one of these snakes.
Factual error: In this episode we see Blithe get shot in the neck and are told that he died in 1948. In reality he was shot in the shoulder and survived. He later served in Korea and was promoted to master sergeant as well as receiving the paratrooper of the year award. Blithe died in 1967 while on active duty in Germany.
Factual error: The verse Octavia recites is from Virgilius' poem "the Aeneid". That poem was written at least a quarter of a decade after the death of Caesar.
Factual error: Aetius' troops don't look anything like 5th century Roman soldiers. They are carrying a large rectangular shield, a pilum (a spear which was used for throwing) and a sword (gladius) on their right. This was typical for the Roman army until about the 3rd century A.D. In Aetius' time, the soldiers would have had smaller oval shields, a hasta (a lance used for stabbing and for fending off cavalry attacks) and a sword (spatha) on their left. Also, there would be an enormous amount of "barbarian" mercenaries in the Roman army (Goths, Vandals, even Huns.), so it was hardly a Roman army anymore. And where's Aetius' cavalry?
Factual error: In the Pope's coronation procession they play the anthem Zadok the Priest. It was composed by Handel for the coronation of George II in 1727, 235 years after this coronation took place.
Factual error: The Secretary of the Air Force enters a room. A captain not in uniform salutes him. You do not salute out of uniform, and you do not salute civilians. You stand at attention. (00:09:20)
Episode #1.1 - S1-E1
Factual error: The American flag shown waving outside the White House is the current present-day flag with 50 stars. From 1896 to 1908, (the time period that this show is set in) the US flag only had 45 stars as Oklahoma, New Mexico, Nebraska, Alaska and Hawaii were not recognised as states in that time period. The flag did not have 50 stars until 1960. (00:04:30)
Factual error: Captain Souter is shown lying dead in the snow following the massacre at Gandamak. In fact, Thomas Souter was one of the few who survived to be captured by the Afghans and was later freed.
A Father's Great Expectations - S1-E1
Factual error: When JFK leaves to become a PT-boat commander he is wearing full lieutenant's rank insignia. He was actually a lieutenant junior grade when he took command of PT-109.
Factual error: Dr. Johnson completed his dictionary in 1755, 7 years before the Prince Regent was born (1762). So it's unlikely for him to be asking the Prince for patronage.
Factual error: Disc 2: There is a scene where a cannon shell explodes inside a hospital ward. Everyone in the ward is killed, but there are no signs of limbs torn off or even shrapnel wounds, only some blood here and there. The same thing happens at the Battle of Bull Run when the old woman gets blown out of her bedroom by cannon fire. (01:32:00)
Factual error: In the opening, a number of Lancaster bombers are flying over Windsor Castle, they did not come in to service until 1942. (00:00:20)
Factual error: Throughout the series, traffic in Pakistan is depicted driving on the right. In Pakistan, traffic drives on the left.
Factual error: The battalion commander wears the correct crown and pip of a lieutenant-colonel, but the four cuff rings of a full colonel (lieutenant-colonels wore three).
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.
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.
Factual error: The Essenes climb Masada bearing the scrolls. Just as Joseph Wiseman is framed solo, a black SUV drives from left-to-right below him on the road.
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: At the end, Daniel Boone is met by the Marquis de Lafayette, played by an actor in his 60s. When he arrived in the American Colonies to aid the revolution, Lafayette was 19 years old.
