Factual error: Rob Base and DJ E-Z Rock's "It Takes Two" was not released until 1988. This movie takes place in 1987.
Factual error: Our heroes find a boat belonging to shark poachers, smashed to pieces by the Meg. Floating about in the debris are the bodies of a number of dead sharks. Sharks do not have swim bladders and dead sharks do not float - they sink.
Factual error: Aquaman lifts a submerged submarine towards the surface, which should start to sink again straight after releasing it, as its ballast tanks are still full of water. It shouldn't stay floating like that.
Continuity mistake: When Klaue is being rescued by Erik, the amount of blood from his face wound changes between shots.
Continuity mistake: When Anne breaks up with Eddie on the sidewalk right after they get fired from their jobs, she approaches him and drops the box she is carrying. A ceramic mug falls out of the box. There is both visual and audible confirmation. After putting her ring in his shirt pocket, she bends to pick up the empty box and proceeds to walk away without also retrieving the missing contents. (00:14:45)
Factual error: During the plane ride into France, the Paratroopers are holding/carrying their weapons by their sides. In reality, their weapons (M1 Garands, B.A.R.s, etc.) would be carried in special "bags" strapped to their parachute harness. This not only protected their weapons, but also secured them to their person.
Plot hole: Being transported from the west of Costa Rica all the way to Northern California by ship would take about a week. Are we to assume that Owen, Claire and Franklin were staying put in the back of the truck the whole time undetected? They would have to eat and use the restroom, at least.
Suggested correction: Maybe they did have to sneak around but the director thought making us watch Owen sneaking away at night to take a whiz wasn't really important to the plot.
It was established in the plot's timeline that the ship travelled overnight. A ship like this travels at about 12 knots and would take for them about 9 days to complete that voyage.
Plot hole: In all scenes where special or heavy items are used against the sixers, they are 'zeroed' in waves or circles. This can be seen by their stations turning red in clusters. This makes no sense as the stations have fixed positions, meaning that the sixers would have identical positions in the Oasis and have no freedom or own will to move relative to each other.
Suggested correction: From a military point of view it makes perfect sense. AOE weapons would be most likely to hit members of the same squads, companies or battalions. It would make sense for squad mates in the oasis to stick together in stations as well. I just watched that scene. As long as the Sixers are trained soldiers or players it makes perfect sense.
Other mistake: Davis tells Kate to go and she jumps out of the falling plane, her chute opening. Davis then takes a minute to free Harvey from the plane as it's still falling before they both get out. Once they are free falling he takes a few seconds before he pulls their chutes as well. However as they are coming down close to the plane crash site, Kate is near level with them in altitude as they are all coming down together. With how high she was when she jumped out compared to the time it took for Davis and Harvey to get out of the plane and open their chutes, she would have been several minutes behind them in the sky, not right next to them. (00:47:45 - 00:49:05)
Suggested correction: She jumped first and would have already descended in altitude. Then the guys jump and freefalled and pulled their chutes so it is plausible they caught up to her altitude when their chutes opened.
Continuity mistake: At the school, when Scott's suit is malfunctioning and he's big in the janitor's closet, his head is tilted towards his right shoulder. When Hope is working on the suit, we see Scott's head is now tilted towards his left shoulder, even though he's stuck and wouldn't have been able to move around like that. But in the next shot it's back to his right.
Continuity mistake: When she is in the boat she takes off her blindfold entirely, but after some talking the blindfold is around her neck all of a sudden.
Continuity mistake: When Jake is serving the cream he uses his left hand, then right, then left again between shots.
Continuity mistake: During the fight at Aunt May's house, May knocks Tombstone out of the house with a bat. The subsequent shots have him back in the house.
Continuity mistake: When Newt is straddling Thomas with a knife pointed down at his upper left chest, it's very obvious that the knife goes into his chest, through Thomas' shirt. A few minutes later, when Thomas is kneeling over Newt, after Newt stabs himself in the chest, the stab hole in Thomas' shirt is no longer there and he isn't bleeding. (01:50:45)
Plot hole: There is no way Anna could know that Hester was going to be at the auction. The circumstances that led to Hester and Tom being captured can't possibly have spread to the Anti-Traction League, they were immediately taken to the slave auction after being captured. Anna also instantly recognizes Hester when she sees her despite the fact that Hester was 8 years old the last time she would have seen her.
Suggested correction: Anna might have very well just been there to do anti-tractionist things, it was an auction made of towns after all a prime target to hit many options at once or hide bombs on for a bigger city to gobble up and go off later. Once she saw Hester her plans simply changed. As for how she recognized her, it is possible Anna had been tracking / keeping an eye on her. It wouldn't be impossible to ask around for a scar faced girl moving from town to town and might have gotten a pic somewhere.
These are all wild guesses that aren't confirmed by the film itself. They do not qualify as corrections.
Character mistake: During an intermission following Dmitri's revenge after the attempted hit on him, the Chief of staff discusses the data with Dr. Updale. There's a pie chart in the screen in the background, and the segments are; 5%, 25%, 16%, 14% and 50%, which add to...110%. It's not a pie chart, it's a pie and a slice. (00:50:15)
Continuity mistake: When Stallone kills the bad guys with skull masks in the corridor of the bar, his motions pointing the pistol don't match the positions of the lemming-like goons he hits. For instance he has the gun all the way to his right for the first one he kills, but the guy is shown with a hole opening in his forehead while he's in the middle of the corridor. (00:29:00)
Character mistake: Immediately after the crash, when Reeves is carrying his youngest child Sophie, the actress opens up her mouth, even though she has already drowned. (00:14:43)
Factual error: Cat Rivers is flying the R44 helicopter from the left seat. The R44 is a single pilot helicopter fitted with dual controls. Two collective levers may be installed (the left is removable) but the cyclic control is not of a conventional nature. This comprises a central stick terminating in a pivoting T bar, which only allows one of the pilots at any one time to control the cyclic with the hand grip in the 'normal' position. The R44 is normally flown from the right seat; it is possible to fly from the left seat and instructors regularly do so. Students and low experience pilots would normally only fly from the right seat, and are discouraged from flying from the left seat when with friends. This is because of the unusual cyclic control configuration and, to some extent, the different instrument scan and visual references for hovering when flying. (00:14:40)
Continuity mistake: In the car at the start, when Hamilton says it's like the fourth blackout today, Michael corrects her and says it's the fifth. When he says this, he is leaning forwards some as he looks up out the windshield with his mouth partly open. It cuts to a different angle and suddenly he's leaned back in his seat fully and his mouth closed. (00:01:30)
