Factual error: If the Russian cosmonauts need special suits to survive out in space, so should Lacy when she is abducted by Nuclear Man. (00:02:50 - 01:20:20)
Factual error: In the DJ spin-off scene, Zach and Francessca help make Meeker cool by going into hypertime and giving him a dance lesson. At one point, we see Zach and Francessca in hypertime making Meeker do flips. Then, in real time, we see that Meeker is doing the flips at the same speed that he was doing in hypertime. Wouldn't he be going a lot faster in real time, not the same speed as he was in hypertime?
Factual error: Proteus refills its air supply in the lungs. The lungs are filled with normal sized oxygen molecules. How are they supposed to breathe them? (In the book, they had a miniaturizer on the sub, but there is nothing in the movie to explain this.)
Factual error: When they're first entering the whaling camp, a penguin startles Miller. That penguin was a black-footed penguin, which is a bird native to much warmer climates. If that little guy had actually been in Antarctica, he would have died within minutes. (00:20:40)
Factual error: Laredo drives the ship out of the starship docking station and scrapes the main hull on the walls. This would not be possible without either scraping the wings first, as they are much wider than the main ship, or turning nearly sideways, which they clearly don't.
Factual error: Shazam catches the bus with his hands, but it lands on his hands and face by the windshield. This puts the entire weight of the bus being supported by just the front windshield held by Shazam's hands, plus the momentum of it falling from the bridge hitting him. No way the glass could support all that and not break. Especially since it already cracked from just a guy falling on it.
Factual error: Winter in Antarctica would not have a night and day as portrayed, with the amount of light changing so much during the course of 24 hours.
Factual error: The geography around the VLA in New Mexico is actually relatively flat - in fact one of the reasons why the array complex is there is because the land is flat. The canyon in the film was actually Canyon de Chelly, in Arizona, more than 170 miles (270 km) away. But in the film, when Ellie goes to the canyon, the radio antennas seem to be right there, insinuating that the canyon is part of the VLA's magical desert scenery.
Factual error: While the problem with refuelling the SR71 is a real one for D.A.R.Y.L., he is never going to get that far. The SR71 had no self starters and required a trained crew with a starter generator mounted on a truck to get the engines going in the first place. D.A.R.Y.L. just pushes a button and away he goes. Not likely.
Factual error: When Shorty is removing Jennings' memories in the beginning, the pictures shown are from a third person viewpoint. If they are his memories, shouldn't these be from Jennings' viewpoint? (00:06:40)
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.
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: In the begining at the bridge ceremony, the band plays Manhattan Beach by John Philip Sousa. However, Manhattan Beach was composed in 1893. (00:00:50)
Factual error: In the underwater scene when Rex blows up the ice pack, ice appears to be denser than water in this situation. The ice sinks when it's blown up, and even if there were pieces of metal on top of the ice, it shouldn't. Some pieces the size of a five-story building have no metal and still sink. (01:43:00)
Factual error: Erik arrives in Argentina at a place called Villa Gesell, shown to be a town in middle of mountains. Villa Gesell is a beach town on the Atlantic Ocean coast, with no mountains.
Factual error: The suits worn by dangerous disease researchers would definitely never tear if the hose was pulled.
Factual error: The solar panels (or mirrors) are facing away from the sun. The sun's position can be estimated from ground shadows and object highlights and the panels are facing in completely the wrong direction. (01:11:40)
Factual error: In a few scenes at the hotel by Heathrow Airport, several British Airways aircraft are seen, all with the current paint scheme instead of 1995's.
Factual error: The Apaches in the film are depicted with dual machine guns on each side of the cockpit, mounted directly on the windows. In real life, Apaches cannot mount such cannons, and instead use an M230 Chaingun in a turret underneath the helicopter, which the film Apaches have, but for some reason do not use. (00:49:25)
Suggested correction: Yes, we can all see they are supposed to be Apaches but not once are they mentioned by name. The US Army obviously didn't allow for real Apaches to be used. This isn't a mistake as there would have been no official licence to use the real deal.
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.
