Factual error: When Sam climbs outside the ship he grabs the frozen metallic pipes and rails with both hands - one half covered with a glove, one is bare. He has no problem gripping the cold metal and he can get his hands free every time. If the moisture froze before contact, his hands would be frozen too, so that can't be the reason.
Factual error: All the scenes which are supposed to play in Zürich were being shot in Prague, the capital of Czech Republic. The director didn't choose Zürich because the city was too clean for him. The signs on the walls are sometimes written in Czech language, and the people speak German with a strange (Czech) accent, not like someone from Zürich.
Factual error: The action takes place around the second half of June (either side of the Glastonbury festival weekend). At the beginning of the film leaving work early evening in time to get home for dinner, in the UK, it wouldn't be dark. Later on, there isn't that much snow in the Alps, especially below the tree line, at that time of year.
Factual error: In the gunfight on the Nile-boat, you can often see (and hear) Rick fire his revolvers 20-24 times in totum without reloading. The guns he has would only take 6 rounds per gun (MAS 1873 revolvers).
Factual error: In the beginning of the movie William supposedly boards the train in Lincoln, Nebraska. All the vehicles in the train are from Europe and never rolled in the United States. (00:03:35)
Factual error: In the scene at the Bangkok docks, the ship has the name Athena but with the Greek letter Lambda instead of each capital letter A. This would make the name something like Lthenl, and is a nonsense mix of Greek and English (Roman) letters.
Factual error: When Grace is fighting the controls of the C-5 cargo aircraft there is a shot of part of the instrument panel. Among the items on the panel is a switch labeled "tail rotor quadrant." The C-5 does not have a tail rotor. Helicopters do. (01:35:00)
Factual error: When Goodspeed crashes the Ferrari, his airbag deploys and he must shoot it to get out of the car. In reality, airbags inflate and deflate again in less than a second - the gas escapes through vents or the material itself, so there's no way for one to stay inflated.
Factual error: The actual Tsavo lions responsible for the killings had no manes - see for yourself; they are on display at the Field Museum in Chicago. [The filmmakers employed artistic license in using maned lions. They were also certain to include - at the very end of the movie - footage of the real Tsavo man eaters, as they appear in the Field Museum.]
Factual error: Near the end of the film Butch is complaining about the living conditions they have to endure - jungles, swamps, snakes, night work - and Sundance sarcastically retorts "Bitch, bitch, bitch!" In 1908 the term meant just what it literally means: "Female dog." It did not adopt its current meaning of "complain" until much later. At the time the film is set - outside the context of "female dog" - it was considered to be a serious obscenity, and it would not have been used to describe something as ordinary as someone moaning about his living conditions.
Factual error: John Wayne and James Caan are in the gunsmiths shop, and behind the gunsmith on the shelf are some products, one of these products is Bugler tobacco. Bugler tobacco was introduced in the United States in 1932. (01:00:00 - 01:02:00)
Factual error: When Oddjob has the Lincoln crushed at the junkyard, it is smashed into a small rectangle, and dropped into the little falcon pickup. Even though the crushed car fits into the bed of the Falcon, it still weighs at least 2 tons. That weight would have dropped the back of the truck to the ground, but the truck doesn't even squat a few inches, let alone being able to handle that load with the tyres it has. (01:16:55)
Factual error: The word "intel", used several times, is first recorded in 1961. It certainly wasn't in use in 1918.
Factual error: When the air hose on the truck is severed, the brakes release. In reality, on an air-braking system, if the air hose is severed, the brakes lock on as a safety measure.
Factual error: The elevator Cade leaves because there's "too much weight" shows in the next scene a weight limit of 680kg. Even if the four passengers weighed 90kg each (a total of 360kg) it would mean the seed weighed more than 320kg (over 700lb), which would mean that Joyce would never be able to carry it alone as he did several times.
Factual error: When the action moves to England after the failed award ceremony, the British Union Flag hanging from the wall is upside down. The broad white band should be at the top left (nearest the top of the flag pole).
Factual error: When Howard is running after the bouncy ball he is on the second floor of the Mall of America, however, you see him run through the LEGO store which is located on the lowest floor of the Mall of America, which is impossible if he was on the second floor before.
Factual error: The heat from Dutch's body would warm the mud up in a matter of seconds (tested by the Mythbusters). It doesn't even cover all of his skin or his eyes. And the Predator isn't filtering his input for only large heat sources. His normal vision tracks in on a rat hiding just above Dutch.
Factual error: There is a scene with several flags hanging on the wall of the castle. These are supposed to be flags in the Middle Ages. However, one of them is the present day banner of the Hungarian Republic (where part of the movie was shot).
Factual error: The crescent as emblem on Saracen pennants is anachronistic as it appeared on Islamic military flags no sooner than the 15th century A.D.
