Factual error: The radar guided SAMs are consistently evaded/triggered by the pilots' flares, which in reality only work against heat seeking missiles. Radar guided missiles would be defended against using chaff, basically clouds of aluminium foil strips. It was mentioned in some interviews they didn't want use chaff as it wouldn't really be visible for the audience - hence why they only deploy flares.
Factual error: The deer in the forest somehow does not hear the giant dinosaur approaching, so doesn't run away. (01:21:10)
Suggested correction: A different interpretation is that the deer knows the difference in the sounds - gurgling/roars of an approaching herbivore versus carnivore - so it didn't perceive it as a threat until it got unusually close (so the deer looked to see why). The dinosaur flung the deer aside, then proceeded to eat the vegetation where the deer was. It isn't likely that the dinosaur (if a carnivore) would toss aside a fresh deer meat brunch in favor of some green brush.
The therizinosaurs were herbivores.
Factual error: The Skycrane helicopters have a max takeoff weight of 42,000 lbs. With them weighing in at 19,200 lbs, that leaves 22,800 lbs that they could lift. Even small carracks, the ships, weigh around 180,000 lbs.
Factual error: El Paso, Texas, where the entire movie is set, is nowhere near the ocean or large enough bodies of water where a marina with moorings for megayachts could be located. The yacht scene, while fanciful, could not have taken place in El Paso or anywhere reasonably nearby (even by US standards).
Factual error: The satellite phones don't work as they should. They're somehow still able to use them to communicate after the moon has got close enough to the earth to cause enough damage to the satellite network that it'd no longer function, and can also make and receive calls while under tons of rock.
Factual error: The opening states the location as Bristol, England. Santa is drinking in a pub on Shirely Street (neither the pub or the street exist in Bristol), then shortly after is shown leaving from the rooftop, on his sleigh, with multiple high rise buildings in the background. Bristol does not have high rise buildings in the main city centre, only a few blocks of flats, which all have flat roof tops, not like those depicted.
Factual error: At the beginning they talk about an explosion in Istanbul but when they zoom out the location is the west coast of Saudi Arabia.
Factual error: Mount Fuji lies near Tokyo. Yet you see Mount Fuji from the train between Nagoya and Kyoto. That is not possible.
Factual error: Mary Jane said, "I spent seven days in a pitch-black shipping container with no food or water and nine other girls." A human can go 2-3 days without water, but not 7. (00:37:18)
Factual error: Lieutenant Hudner comments that he went into the Naval Academy right after Pearl Harbor. Pearl Harbor happened in December 1941 and he couldn't have gotten into the Naval Academy until 1942. Then he says, "The war ended a month before he graduated." The Naval Academy is a four-year school. That means he wouldn't have graduated until 1946, a year after the war ended.
Factual error: One of the warriors tells a trainee they move like a sloth, more than once. Sloths are only found in the "new world", not native to Africa.
Factual error: The parachute flare was not invented till 1922. This film takes place in 1918 but features one. (00:21:15)
Factual error: When Danny and Sarah cut in front of the truck to take another route, there were at least 14-17 bullet holes through the rear window alone. Glass on that year of Mustang was not laminated and the bullets would have struck them. (01:27:35)
Factual error: When Martine enters the passcode to reveal the bats, you see her hit "3" first followed by what seems to be "5" (the rest is blocked by her body). She then tells Michael his passcode is the first 6 digits of pi backwards. The first 6 digits backwards would be "951413."
Factual error: Pettis' calculation of the amount Connor needed to replace his asset was way off. He stated, "[Cornell] brought me about 250 [$250,000] a year. He had at least 20 more years of service. Subtract five years he might have spent in prison, so you owe me, what? Six point two million." Pettis was presented as intelligent, but a quick mental calculation of even the full 20 years at $250,000 would total only $5 million (not $6.2 - an odd sum). For 15 years, the total would be $3,750,000. (00:28:45)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Factual error: Sam Cooper's Rx label was for Alprazolam (generic Xanax) 2 mg, qty #150, refill 2x, and "take 1 tablet by mouth as needed." "Must last _" length was not visible and there could have been warning stickers (may cause drowsiness) on the other side. However, Xanax is a fast-acting tranquilizer which should last 6 hours and the dosage should not exceed 10 mg per day. The instructions to "take 1 tablet by mouth as needed" should have had restrictions attached to prevent serious side-effects/death. (00:49:38)
Factual error: The film gets basic physics wrong while trying to depict relativity. Buzz Lightyear leaves T'Kani Prime for a trip around its sun, travels with near-light speed, and returns four years later. This could only have happened if T'Kani Prime's sun were at least two lightyears away! It gets more ridiculous. Buzz's last trip takes 26 years, even though he has traveled at faster-than-light speed. Overall, T'Kani Prime is experiencing either a mysterious time slow-down or a rapid orbit expansion.
Factual error: When the Allosaurus bent over to pick up her egg (which was almost touching a newly-thrown hand grenade), the hand grenade exploded only toward the right of the screen, engulfing the dinosaur. A hand grenade would/should explode in all directions. (01:19:30)
Factual error: The nuclear missiles are shown in flight numerous times. They're travelling horizontally, and have their rocket motors on. Except that long range nuclear missiles are ballistic, and follow a curved path to and from space. And their rocket motors are on only for the thrust phase of the flight, and not halfway to the target.
