In San Francisco the prostitutes jump off a wagon full of beer barrels marked 'Pabst Blue Ribbon.' It was called Select until 1882. Due to their practice of tying a blue ribbon around the neck, it was frequently asked for as 'that blue ribbon beer.'
When the train stops after the Native American raid, the train station sign says "Fort Kearney", and the station manager mentions a local train that will run to Omaha. In 1872, the sign should have read "Kearney Junction." Fort Kearny (correct spelling) was shut down in 1871. A postal error added a second "e" to Kearny, Nebraska, and the spelling has been Kearney ever since.
When the American train stops unexpectedly, for the pow-wow with the Indians, and later, when the buffalo are stampeding across the tracks, the locomotive is behind the same cluster of bushes. Incidentally, the railroad would never allow foliage to grow that close to the right-of-way. They would cut it back, to avoid track fires caused by stray embers dropped from the engine.
Passepartout sits at a table in a San Francisco saloon. Someone throws a knife, which lands on the table next to his hand and knocks over a glass of beer. In the next shot, the glass is upright and full of beer.
When the SS Rangoon approaches Bangkok, its hull is white. As the evening progresses, while Phileas Fogg impresses Princess Aouda with tales of his prowess at Whist, the hull is black in brief closeup scenes. A long shot of the Rangoon as it enters Hong Kong harbor reveals a black hull.
When Passepartout tries to escape the Sioux on horseback, his horse leaves a trail of dust. The dust pattern changes completely at one point, revealing 2 scenes spliced together. A large rock in the background provides a shadow to fully observe it.
At the beginning of the movie, when Passepartout is on his way to the employment agency on the high-wheel bicycle, a white horse comes up beside him and even next to him. In the next shot, the horse is gone.
When Inspector Fix and Passepartout are in the bar sitting down and talking, the inspector's left hand is on top of his walking stick, with his right hand on top of his left. A moment later, his hands are reversed.
The scenes set in Yokohama, Japan, were shot in Kamakura, west of Yokohama, and Kyoto, far southwest of Yokohama. The film makes Kamakura's Great Buddha look like it's walking distance from Kyoto's Heian Shrine, but they are in separate regions of Japan.
On her way to Hong Kong, the S.S. Rangoon passes the Royal Palace at Bangkok (Siam/Thailand). However, that would've been impossible. Even in 1872, the Chao Phraya River was much too shallow for ocean-going vessels of S.S. Rangoon's size at that spot. Bangkok's port is situated some 15 kilometers downstream near the river's estuary, where the water is deep enough. Also, the S.S. Rangoon is going the wrong way, passing the palace from left to right, suggesting she comes from upriver and sails towards the estuary, which doesn't make sense either..
As Fogg and Passepartout prepare to leave Paris in the balloon, the basket is on the ground and a rope extends about eight feet to the side of the basket, where it is tied to a pile of sandbags to keep it down. When Passepartout unties the rope the balloon begins to rise. If the rope had actually been holding the balloon down, it would have be vertical and taut because the balloon would be above it.
The locomotive used for the American train sequence is named the Jupiter, one of the locomotives at the Golden Spike ceremony. However it's a 2-8-2 freight engine with small drive wheels. The real Jupiter was a 4-4-0 passenger locomotive with large drivers. The locomotive in the movie is powerful but slow, and would never have been used to pull a passenger train on the prairie.
When Fogg and Passepartout cross the mountains in the balloon at high altitude, both are wearing light clothing and no gloves when opening the champagne. The air temperature around them would have been freezing, yet they show no signs of being cold.
When Princess Aouda, Fogg, and Passepartout travel in the balloon, the streamers at the bottom of the basket flutter behind them. A balloon moves with the wind, so streamers tend to hang straight down or flutter randomly in the turbulence.
In all close-up scenes with the gas balloon the basket ropes are tight from the load ring and down, but from the load ring and up to the balloon they are slack. Had it been a real flying gas balloon, all the ropes and the net above the load ring would have been very tight during flight, since they are carrying the weight of the basket and everything in it. The lifting force, a stage crane, is erroneously placed in the center through the appending gas valve. If the sandbags on the basket actually contained sand, they would not have bounced around so lightly.
The goof items below may give away important plot points.
When Fogg finds Passepartout at the circus in Yokohama, Passepartout races to him, and the human pyramid collapses. The top man of the pyramid grabs the canvas background, pulling it down, revealing the back of the stage and lighting. That type of stage support structure was not used in Japan at that time, and the overhead lights are modern lamps that were not available in 1872.
At Lloyd's of London, Scotland Yard's Inspector Hunter explains that Fogg robbed the Bank of England and says Fogg and his party took the SS Henrietta, bound for Caracas, Venezuela. After confirming that Fogg has bolted, he says the Henrietta is going to Central America. Caracas is not a seaport, and Venezuela is in South America.
After Fogg, Princess Aouda, and Passepartout arrive back in England, they discover that they returned a day earlier than they expected because they crossed the International Date Line west to east, gaining a day. The date line is in the middle of the Pacific Ocean, and they would have had many opportunities to learn the correct date before arriving in England. They had to know the correct date to cross the U.S. and sail across the Atlantic Ocean.
