Factual error: When Ray leaves his wife Gina and his car is hit by the truck he should still be in England, but when he is being chased through the streets he is in South Africa, the cops in the car are not in English police uniforms or vehicle, police livery is incorrect, and all vehicles have South Africa plates, not English number plates.
Factual error: The video games Operation Wolf and Rampage were visible in the Family Amusement Center arcade during the opening. However, this would not be possible during the movie's 1984 setting since Rampage wasn't released until 1986 and Operation Wolf wasn't released until 1987. (00:12:48)
Factual error: The old percussion double barrel shotgun is firing modern shotgun shells, which would never work or fit in that gun, and furthermore are also made of plastic, wrong for the era.
Factual error: During the performance by Sweden there are 7 people on stage, meaning this entry would be disqualified due to the rules of the contest which state no more than 6 people are allowed on stage.
Factual error: The "hard suits" the divers wear have soft, relatively normal gloves and soft joints. More akin to a football uniform with armor over spandex. They are at the bottom of the Mariana Trench, at 36,0000 feet below sea level. The pressure is over 7,000 psi. Without a hard suit, they would instantly be crushed.
Factual error: Smaller pieces of the comet start raining down in a highway setting. While small fragments of a comet can come down, they'd all be traveling at anywhere between 20 miles per second as the comet is an extra-solar comet. Those small pieces wouldn't make such piddling explosions, they'd be creating concussion waves that would rupture your organs and send vehicles flying. The heat even from those small rocks would ignite all foliage within 50-100 yards. (01:31:00 - 01:34:00)
Factual error: When first sucking a bullet from the wall into his gun, he then opens the previously empty magazine to find the bullet. Given he didn't work the slide (forwards or in reverse), the round should not be in the magazine, but in the gun's chamber ready to fire. (00:14:00)
Factual error: The Corvette owned by Bentwood is not a Z06 as shown in the movie. It is a 2014 C7 Stingray and can be identified by the Stingray logo on the side of the car.
Factual error: SPOILERS! While the ending of Al being arrested for murder at his own wedding is dramatic and cathartic, it wouldn't have happened that way. There's no way that the cops would have known to search the wooded area near the cabin; they would have needed to find physical evidence linking the cabin to Al; they would have needed to establish that Al had no alibi for the time in question; etc. None of that would have happened that quickly or that quietly.
Factual error: While on the fishing boat, the flag flown has 50 stars, while the movie is set in 1941. The US didn't have 50 states, and thus that flag, until 1959. (00:30:08)
Factual error: The USMC Embassy Guard is an enlisted Marine Sgt. He is wearing a Commissioned USMC Officer's cover (hat) that has gold braid and gold oak leaf motifs on the visor. (01:20:15)
Factual error: The Blackledges' car has a license plate that starts with 34. Montana uses the first two numbers on their plates to identify the county that the driver lives in. 34 is the number for Sheridan County which is in northeastern Montana where there are no mountains in sight, but the Blackledge ranch is set near the foothills of a mountain range as you would see in western Montana.
Factual error: The soldiers had 506 Regiment's helmet markings of the 101st Airborne, and on their sleeves the 82nd Airborne and 1st Division shoulder patches.
Factual error: Lynyrd Skynyrd's plane crashed in the early evening in October 1977. Injured crash survivor Artimus Pyle, tended to the severely injured people and later was able to walk through the swamp and the woods in the dark to get help, but in the movie when the plane crashes and Pyle's search for help it's a bright sunny day.
Factual error: It is later revealed that Detective Banks partner faked his death by killing a meth-head junkie with the same tattoo as him. He included the junky's filleted skin with the same tattoo in a box with his badge to make it look like the other kills. Police, firefighters, first responders all provide DNA into a data bank to be identified in case something tragic happens and their remains are recovered. William Schenk's DNA would not have matched that of what was in the box.
Suggested correction: William knows that the cops will find out that he's not really dead one way or another. After all, he literally confronts Zeke and reveals he's still alive, knowing there's a good chance Zeke wouldn't take his offer to join him. All he's really doing is throwing off the cops and buying himself a few days when they think he's dead. (Since it can take a few days for DNA analysis to happen.) By the time they figure out he's not dead, he'll have already finished his game and disappeared. Which is ultimately what happens... he finishes his final game with Zeke and Marcus, then gets away.
Factual error: The plot's main conceit hinges upon coders, the art department, and the user-end network team constantly working live at the same time in the same room, as well as developers actively writing code, rebooting servers, and chasing players in-game to get rid of problematic players. No real game company could operate this way. Game content patches wouldn't change the network experience, and in-game aesthetic changes like the ones they make in seconds would require weeks if not months of development.
Factual error: When "some Frida Kahlo-looking asshole" is chasing Harley across the bridge during her close-up you can see that the cartridges are loaded backwards into the cylinder. (00:54:05)
Factual error: When John Thornton is in the bar, Hal comes up and punches him in the face. They fight and argue, and Thornton proceeds to say that Hal "sucker punched" him. However, the term sucker punch was first known to be used in 1926 while Call of the Wild was published in 1903. The story itself took place in the 1890s.
Factual error: Not only Mulan's horse is able to outrun an avalanche (at the beginning even unseen by the large enemy army who does not even notice the event occurring), but it also gallops through it undisturbed while Honghui is being carried away depicted as being in serious danger. (01:09:30)
Suggested correction: This is consistent with what you see throughout the whole film: Mulan consistently breaks the laws of physics because her "Chi" is strong. (Translating it to the Star Wars lingo: Strong with her The Force is.) Five minutes before (video time, not in-film time) she reversed the flight direction of a spear. This is a fantasy film and is supposed to do all of this; we watch it knowing that magic, "Chi", and The Force are not real.
That's a composition fallacy.
Factual error: The river that Tyler Rake falls into near the end of the film, the Buriganga, is one of the most polluted rivers not only in Bangladesh, but in the world. There is no way the water is as clear as it appears when Tyler falls into it. It was done for effect, but nonetheless it's not accurate.
Suggested correction: The river is certainly polluted. But unless you have evidence of the view from under the surface, looking up, with the sun shining down, it's impossible to say that the water in that situation wouldn't look as clear as shown.
