Continuity mistake: The green Alfa in the opening minutes has its side, and mirror, wiped out by a lorry. For the next 5 minutes it then drives around in perfect condition. (00:05:43)
Visible crew/equipment: When Tom and Sonic pull over and the mini drone explodes, knocking Sonic unconscious, the camera pans away and you can see emergency vehicles blocking the road on the right of the screen, presumably closing down the road for filming. (00:59:55)
Factual error: The movie starts in 1985, jumps '5 years later' and then back to Sasha Luss, then '3 years earlier'. So, in her crusty apartment in an impoverished neighbourhood of 1987 Soviet Russia, Anna is filling a form on her notebook-style laptop, too modern for the era. It looks like a NEC UltraLite (considered the first notebook style laptop) which didn't even come out until 1989, let alone the likelihood of someone in the USSR having one.
Continuity mistake: In the final battle, Wasp and Ant-Man are in the van trying to get the quantum tunnel operational. We cut back to the fight and we can see Ant-Man there too, fighting in his giant form. (02:22:20 - 02:23:00)
Continuity mistake: The final battle starts around dawn, and it's very dark when the bad guys arrive, but between shots it suddenly gets much brighter. (01:38:50)
Suggested correction: When you see the helicopter start flying in after Brixton asking them to bring it in, you can see the sun in the distance, so perhaps some time passed by.
But the weapons are only disabled for 6 minutes and the 6 minutes end when they're hooked up to the chopper, which is way later.
Factual error: Carol Danvers' name appears on her dog tags as "Carol Danvers," but US military dog tags list the surname first, then given name. E.g. "Danvers, Carol."
Continuity mistake: Professor Sheldon 'Shelly' Oberon sprains his right ankle when escaping the baboons by jumping to another bridge. Ming Fleetfoot wraps his left ankle later on when they are by the river. (01:11:38 - 01:14:00)
Continuity mistake: At the beginning after the car skids on the road and stops on the left side there are trees and snow but not the road, however the truck hits them on that side.
Factual error: During the battle at the Marshalls-Gilberts, the movie shows mountainous terrain. The real Marshalls and Gilberts are atolls with very little terrain.
Continuity mistake: After the speeder chase, everyone lands in quicksand. In one shot, 3PO is buried headfirst. In the next, he has flipped and his upper body is visible.
Continuity mistake: When Alita is playing the street version of motor ball she knocks over Tanji. In the next shot Tanji is following her in the pack as she scores, then the shot switches back to him on the ground.
Factual error: The gas used at the end of the movie to blow up the hospital was nitrogen, but nitrogen is not flammable.
Suggested correction: The agent in the basement says someone is heating up the liquid nitrogen to an unstable level, but adds that they also have pure oxygen leaking down there, and one spark can cause "these tanks" to explode. We don't know if "these tanks" are the nitrogen or something else that may be explosive, like gas for the emergency generators, and it is the high oxygen levels that make the environment explosive, not the nitrogen, since almost anything burns in a pure oxygen environment.
Oxygen is not explosive. It wouldn't make the environment explosive unless it was combined with a flammable gas. No medical gasses are flammable. It also couldn't be the gas from the generators as the explosions were occuring on each level, not from one central source. Generators are virtually always diesel, which also is very unlikely to explode unless very specific criteria are met.
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)
Continuity mistake: At the beginning of El Camino, Jesse shows a much thicker beard than he had in his final appearance in S5:E16 of Breaking Bad.
Continuity mistake: When Peter and MJ hug on Tower Bridge he gets some blood from his face onto the left shoulder of her jacket. From other angles there's no blood.
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: During Lee Iacocca's slide presentation to Henry Ford II in 1963, there are two slides that reference James Bond. One shows him standing next to the Aston Martin DB5, which made its debut in "Goldfinger" in 1964, and another shows a still image from "Thunderball", which was released in 1965.
Revealing mistake: In the beginning of the movie, when Hellboy is speaking on the phone with "Dad", he's speaking on on speaker, but when the phone shows up, instead of showing a screen of a call on speaker with the duration on the call, the screen shows what would appear if he was receiving a phone call before accepting or declining. (03:35:00)
Character mistake: Some characters use the letter "s" at the end of a Pokémon's name when the plural of a Pokémon is just its name. The best example is when Pikachu says, "Roger must've sent the Greninjas to cause the car crash." Being a Pokémon himself, there's no way Pikachu, out of all characters, would say that.
Other mistake: During the restaurant shoot out between Jr and the bad guys, he takes Sasha's weapon (Kel-Tec P-3AT) and opens fire on the bad guys. The Kel-Tec P-3AT is chambered in .380 and holds 6+1 rounds. During the firefight, Jr fires 9 times. We also see the bottom of a spent casing and it shows .22. (01:12:00 - 01:13:00)
Suggested correction: He needed to hot-wire the van. It's quite possible he could have left the van for parts (he's seen slamming a Leviathan to the ground) or to protect it. It also could have been an illusion by one of Dr. Strange's people.

Sorry but the suggested correction makes no sense. For one Dr Strange's people have no idea what Ant-Man looks like, and secondly Ant-Man would have no idea where to get parts from in the middle of a battlefield, let alone know if alien technology would be compatible. Also the time frame given when the scene plays out allows no time for him to leave the van, this is a legitimate mistake.
Dr. Strange's people don't know what Ant-Man looks like? He entered the battle with them long before they went to the van. Earth has had access to the same Leviathan parts since the original Avengers. If Toomes can make wings out of it in Spider-man Homecoming, it's possible he can figure something out. Clint had passed the glove to Black Panther before Ant-Man is seen in the background. There was plenty of time. He also could have been defending the van while they brought the glove.
There is plenty of time for Ant-Man to have left the van and returned to it. As the scenes play out, Ant-Man and Wasp are in the front of the van trying to hot wire it. The film then cuts to the battle for several minutes, as we see the passing off the gauntlet, which includes the brief shot of Giant-Man in the background. A few minutes later the film cuts back to the van and we see Scott opening the rear door of the van. So there's plenty of time for him to have gotten out of the van, saw potential trouble with the Leviathan, turned into Giant-Man to stop it while letting Hope finish activating the tunnel, and then returning to check the final settings. Now, all this raises another question that has to do with the apparent ease Giant-Man has in traversing the battlefield, as in why not just give Scott the gauntlet, have him turn into Giant-Man, take a few steps over to the van, and then shrink back down to take the stones back in time?
