Factual error: Sloth bears are one of the smallest bears on Earth. Baloo is a sloth bear, but he's about the size of a grizzly bear.
Factual error: The TV remotes of the day wouldn't control more than one TV at a time, yet they all come on and go off at the same rime.
Factual error: When Vince Edwards is marking months off the calendar he marks months off on two consecutive years that have the same days of the week. That never happens.
Factual error: Cagey Joe's pullover definitely looks more 1976 than 1926.
Factual error: During the dice costume dance sequence, the dice are incorrectly designed. Opposite sides of real dice add to 7. i.e.: 6 is opposite 1, 5 is opposite 2, 4 is opposite 3. However, the movie costume dice are 6 and 4, 5 and 3.
Factual error: When the stork is flying to deliver Dumbo, the map shows the state of Kentucky above Alabama and Mississippi instead of Tennessee. (00:07:15)
Factual error: At the end of the movie, Lady has four puppies, three Spaniels, like her, and one mixed breed, like Tramp. Realistically, they would all be mixed breed with characteristics from both parents.
Factual error: At Portobello Market, when the kids are eating, there's a sign that reads "cookies." No chance there would have been anything like that in 40's London. It would definitely have read "biscuits."
Factual error: The first shot of the calendar shows two days numbered as 20 and March ending on the 24th. In the following shot it's fixed.
Factual error: In the scene with the brandy at the beginning of the voyage, Long John Silver says that the brandy was laid down by the brothers of Buckfast Abbey, vintage 1737. The monasteries were closed in England by Henry VIII in 1538-1539. Buckfast Abbey itself was surrendered to the king on Feb. 25, 1539, and soon demolished. It did not reopen until 1882.
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: One does not simply walk (or run) onto or off a U.S. Navy ship. Every individual coming aboard stops at the head of the brow (gangplank to civilians), faces the ensign (flag) at the stern and salutes, then turns to face the officer of the deck (OOD), salutes again, and says, "Request permission to come aboard, sir." The OOD returns the salute and says, "Permission granted," whereupon the individual steps off the brow onto the ship. A similar procedure is used when leaving the ship, with the individual requesting permission to go ashore.
Factual error: During "On the Atchison, Topeka and the Santa Fe", the train depicted is a Baldwin-built 4-4-0 no. 49, the "Wm. B. Strong." The actual AT&SF no. 49 was a 0-4-0 named "Vulcan", built by Hinkley in 1876. "Wm. B. Strong" was actually AT&SF's second no. 2, and was built in their Topeka shops in 1881.
Factual error: A scene in the second half of the film pans up over the top of the Flamingo hotel/casino facing north up the Vegas strip. The Caesars Palace sign is to the left (west) and north of the Flamingo are the Sands, the Dunes, and the Frontier casinos in that order. The Dunes hotel/casino was never located between the Sands and the Frontier. It was in fact one of the southernmost located casinos on the strip at that time and would have technically been behind, southwest of, the Flamingo in this scene.
Factual error: In Danny Kaye's song about "The Emperor's New Clothes" he persistently and repeatedly uses the words "the king is in the altogether." Hans Christian Andersen lived from 1805 to 1875, but the expression "in the altogether", meaning naked, was invented and popularised by George Du Maurier in his novel "Trilby" which was not published until 1894.
Factual error: At the end of the movie, Mame takes Peter with her on a trip to Siberia. However, at this point in the timeline, it's the late 1940s, meaning that Stalin was still in power, so even Auntie Mame would be crazy to think of vacationing in Russia. Not to mention the difficulties of getting Peter a visa to travel to the USSR at the last minute. (In the stage version, the destination was India, rather than Siberia, which makes a lot more sense).
Factual error: In the opening, they are playing 'Life in the Fast Lane' by the Eagles, and they do a closeup of the studio turntable playing the last song on an album, but 'Life in the Fast Lane' is the second song on 'Hotel California' - not the last. (00:04:24)
Factual error: Sailing ships in harbor always have their sails furled and stowed, not set. All the ships in the city's harbor have their sails set. Would never happen.
Factual error: When Jeremy and Jack climb the beanstalk and arrive on the clouds, it starts to rain. Where is the rain coming from?
Factual error: Ma Tatum, while bemoaning Pappy's misfortune, sits herself on a burlap bag marked "Mash". Mash, the basic component of moonshine, is a semi-liquid, and couldn't be stored in a burlap bag.
