Factual error: When Gregor shoots the guy in the car after nearly killing the little girl, blood sprays over the window, but there's no bullet hole. If the bullet exited his head, hence spraying blood, it should have gone through the window too. (00:55:00)
Factual error: In the scene at Lord Cornwallis' outdoor party celebration, right after Benjamin Martin and his Continental Army blow up a British ship, one of Lord Cornwallis' captains throws back a big gulp of his drink from his martini glass in grief and disbelief - the problem is this movie takes place in the late 1700s and the martini glass wasn't invented until the 1920s.
Factual error: Let's go by the movie geography; our planet is a big matrioska. By diagrams shown, this Hollow Earth would be by the Earth's core, thousands of miles deep. They enter from a portal in Antarctica. And yet, Godzilla later in the movie burns a random hole in the ground in HK deep enough to reach it, roars through it and Kong hears it, and the ape easily climbs it to poke back to the surface. Even admitting you can do the magic "1,000 miles in 2 seconds" warp anywhere, the scale is ludicrous.
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: After the soldiers' initial disembarkment they are shown crouching in groups near the shore and later running towards the bunkers. Unlike the movie shows, anything even as simple as crouching behind the tank traps, let alone actually standing up and running, was impossible at Dog Green Sector and indeed for anyone when pinned down by a machine gun from a high far-away position. In the real-life landing at Dog Green within 7-10 minutes all the officers of the landing company were dead and the survivors inert. They could do nothing except throw away all their equipment and slowly crawl up the beach, shielded from bullets by the incoming tide and dead bodies. 1 hour 40 minutes after landing twelve (known) survivors made it to the base of the cliffs. Only 2 had enough strength left to go on and fight with another group. (The second wave, apart from one boat which was almost entirely killed, opted to land elsewhere when they saw the fate of the first wave.) In this way the movie rather poorly represents what it meant to make a properly opposed landing on D-Day - although whether this is justified or not is another matter. (00:07:00 - 00:07:40)
Factual error: Druig leads several warriors outside Tenochtitlan as it was sacked by the Spanish conquistadores, and they live peacefully in the nearby forest, for 500 years. The forest is of course the virgin Amazon forest, as captions say. Small problem; Tenochtitlan was in Central Mexico.
Suggested correction: It never says that the people who live with Druig in the Amazon in the present day are descendants of the people from Tenochtitlan. Nor does it ever say that the forest outside Tenochtitlan is the Amazon. He's probably been moving around for the last five centuries just as the other Eternals have.
Never ever? He literally says "Do you remember this forest? Beautiful. It's the last place we all lived together. I've protected these people for 20 generations." They split after their argument during the sack of the town. If their base of operations exterminating the mutant space dogs in Mexico was in the Amazon forest, their logistic could use some work.
Just because the last time they fought together was in Tenochtitlan doesn't mean that was the last time they lived together. They may have spent some time living peacefully in the Amazon before moving north to do their business in Tenochtitlan. And just because he's protected the people for twenty generations doesn't mean they're descendants of the people from Tenochtitlan. He may have found them later. We don't know every detail of the Eternals' history. You're just making assumptions.
You are assuming the presence of a third party stranded for 500 years that the movie never showed before, different from the people that he led out of the city and that we have then to postulate he let go, in a location far off from the one of their last encounter. It's an assumption on entirely new details that you had to make up. My only assumption is to think that what is shown in the movie had purpose and fits, and someone just borked a caption.
Who says they're stranded? He just said he had protected them for twenty generations. They'd probably always lived there. You're making the assumption that they must be the same people because nobody said they weren't. But nobody said they were either. Nobody in the film ever made a connection between the people in Tenochtitlan and the people in the Amazon. No mistake has therefore been made in either the dialogue or the captions.
I noticed the same problem, the scene indicates the location as "Amazon" (it could be any of the Spanish speaking countries that have part of this forest), but then, Druig comes with the affirmation you pointed. It's obviously a geographical inaccuracy.
They don't speak Spanish in the Amazons.
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: After the naval battle, Thraex is waiting for an informant who tips him off about Lucilla and Marcus Acacius's plans. And of course, as a well-educated gentleman of 200 AD, he kills time by reading the newspaper. Wait, what? Needless to say (to anyone but Ridley Scott, probably), ancient Romans wouldn't/couldn't exactly get their news by newspaper, the press having not been invented yet. This one looks so modern in its layout it even has headlines and a proper publication title, "Roma Viridia."
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: In the car at the beginning of the movie, Jean uses her telekinetic powers to switch the radio from a station playing "By the time I get to Phoenix" by Glen Campbell to Warren Zevon's "Werewolves of London." It's 1975, and Zevon recorded the song only in 1978 (although the song itself had already been written in 1975, other artists played it in live concerts in the Fall of that year). (00:01:30)
Factual error: When the order is given to activate the US Navy 6th Fleet, the warships are shown with their crews standing on deck in their dress white uniforms, which is only done when pulling in or out for a deployment, or ceremonial port call (fleet week). (01:33:00)
Factual error: When Xander Cage is chasing Xiang on the dirt bikes, he lets his bike get entirely submerged, which would flood the engine.
Factual error: Chris Kyle did not make Chief after his first deployment. He made Chief during his fourth deployment.
Factual error: At the start of the movie you can see the Flag of Great Britain on Solomon's ship. The film is set in 1600 and the Union flag didn't exist until 1606.
Factual error: In the final standoff, Smith shoots Hertz by holding cartridges between his fingers in the fire. This is not remotely believable. The casings, weighing much less than the bullets, would have been blasted off while the bullets themselves would have gone nowhere. (01:15:15)
Factual error: Jodie Foster states that as a propulsion engineer, she knows the internal structure of the plane by heart and has worked extensively on it. The problem with that is that propulsion engineers work on the jet engines - which are all on the outside of the plane, on the wings. Sure, a propulsion engineer might have some basic knowledge of the plane's interior design and engineering, but the in-depth knowledge she claims comes from her job simply isn't right - that's the job of avionics engineers.
Factual error: Shane is a lieutenant and the Principal is Petty Officer first class. Shane states the Principal is the senior officer. This is wrong as the Petty Officer is a Non Commissioned Officer, while Shane is a commissioned officer. Shane outranks the Principal.
Factual error: Phil Lowenstein, the navigator, is hungover when boarding the Memphis Belle. It is obvious to all concerned that he was severely intoxicated the night before the mission. He'd be grounded on the spot and confined to quarters – and this happened a lot in real life.
Factual error: A ham radio requires the person to hold down the button while talking. Numerous times in the movie they are talking without pushing the button.
Suggested correction: This is actually subtly addressed in the film. The magic which allows the radio to work across time also allows the two men to speak without pressing the button. There is a moment where Frank wonders what is going on with the radio and presses the button a few times to talk but then notices that he doesn't have to press the button to be heard.
If that was true, then it wouldn't make sense for them to continue to show Frank and John hitting the squawk bar throughout the film.
That is a separate issue. The mistake entry states that you need to hold the button to talk on a ham radio, which is true, but the magic ham radio in the film doesn't require it. If the actors continue to occasionally press the button that could be considered a character mistake but it could also simply be a force of habit by the characters.
