Factual error: During the war games they have Jefferson pose as a major in order to facilitate the commandeering of the ambulance and the jeep. Regardless of their personal feelings in the matter the ambulance crew and the driver and troops in the jeep would be perfectly aware that no black man would ever be promoted to a position of authority in an otherwise all white command. We may find it repugnant today but the US Army was rigidly segregated during World War 2 - and it stayed that way until 1948. Jefferson may have been inducted into a special unit like the Dirty Dozen but considering that the future of the entire mission is riding on their success at the games, throwing it all away like that makes no sense at all.
Factual error: Two rocket lift-offs are shown. For the American lift-off, they show an Atlas-Agena (American) rocket booster but for the Soviet lift-off, they show a Gemini-Titan (also American) rocket booster. Compounding the mixup is that the film's Jupiter capsules are basically just Gemini craft, which are seen atop what the film presents as the Russian rocket.
Factual error: When M and his entourage arrive at Bond's estate, their cars are surrounded by sheep. They then drive on down an unsurfaced road to Bond's house, past a pride of lions he keeps on the grounds. A series of sweeping overhead shots shows us that it is all one huge field, with no fences or the like. Those sheep aren't going to last very long.
Factual error: There is a scene with Benjamin Braddock going to Berkeley, but his car is driving on the upper deck of Bay Bridge which only goes in the direction of San Francisco.
Factual error: In the scene where the escaped prisoner climbs onto the bridge, he's still in Mississippi. The road sign reads "Arkansas 49."
Factual error: When Bonnie and Clyde are killed he is lying on the ground in front of the car, and she is in the driver seat. In real life they were both killed in the car. He was in the driver seat, and she was lying up against him. (01:44:20)
Factual error: Upon completing the task of lowering every wagon, horse, mule, ox and human down to the canyon floor, the settlers proceed to build rafts for their wagons..however, their scout would have informed them that they would be going overland to intercept the Columbia River to the northwest. The Snake River, with class IV rapids, (even now tamed with dams) was no place for the uninitiated to go rafting.
Factual error: The problem with firing a cannon on steam power is to have the boiling water build enough pressure inside the barrel, with no leaks or openings to release it before its time. The professor's scarf and the plug hammered into the fuse hole (which also flies off just before the shot) wouldn't be good enough as pressure restrainers.
Factual error: In the final scene of the movie Elvis and Shelley Fabares are driving in his sports car along a seaside highway outside of Miami Beach. There are mountains along the coast in the background. There are no mountains in Florida.
Factual error: In the scene when the two criminals are in the hardware store, two vehicles are parked outside that are clearly late 1960's automobiles, despite the film being set in 1959. (00:15:25)
Factual error: The narrator near the beginning says Al Capone was born in Italy. He was actually born in Brooklyn NY.
Factual error: "Lucille" is listening to a transistor radio when she washes the car - clear from the size and because the music starts as soon as she turns it on. The first transistor radio wasn't available until 1954, and this movie is set in the very early 50s.
Suggested correction: Another correction points out that this film takes place post-Korean War, so after 1953. The radio fits the timeline.
Factual error: Barbara takes an ancient document out of a filing cabinet. One of the words in its title is HIFTORIE, for "history." The old-fashioned way of writing the letter "s" was the so-called long s (ſ), not the letter "f", and this was only ever used as a lowercase letter. So the word would have been written as HISTORIE.
Factual error: Druids worshipped things like nature, not Greek gods like Zeus.
Factual error: The view of the Golden Gate Bridge from the Drayton's terrace is not in San Francisco, but from the Marin side of the bridge.
Factual error: When Miriam is pacing, waiting for Tony to come home, she is listening to Tony singing "Come Live with Me" on a reel-to-reel tape recorder, but the recorder has no speakers, either built-in or separate.
Factual error: The movie is set in 1922, but the women's clothes are more along the line of 1928, with a strong 1960's influence. For an accurate depiction of 1922 fashion, refer to Season 4 of Downton Abbey.
Factual error: During the Jousting all the knights fail to use their lances correctly by putting them across the horse's neck, instead they just attack each other on the lance arm.
Factual error: When the ambulance arrives the policeman, at the crash scene, is wearing a City of London Police helmet (different from the Met) yet he is in a Metropolitan Police area.
Factual error: The song that Bo and the others use to trick Abdul into thinking there are reinforcements is "Durch die Grune Heide", a marching song used during the Second World War. However, the film is set in 1906.
