Plot hole: When Sarah Paulsen pulls the necklace out of the water, the necklace clasp is obviously closed. Since the circumference of the necklace is too small to fit over the top of Anne Hathaway's head, why would anyone believe that it fell off her when she was running to the bathroom? The only way that could have happened is if the clasp (which we were earlier told can only be opened by a magnet) had opened. The trained security guards wouldn't have suspected something wasn't right about a closed necklace falling off over of her? They were following her. They saw that at no point did she lower her head on her way to the bathroom for the necklace to fall off over her head to begin with. It also could not have fallen off her when she was vomiting into the toilet in the bathroom since the clasp was closed. (01:18:25)
Visible crew/equipment: After burning the car, when Dave takes the trash out there is a camera operator at the end of his driveway. (01:11:00)
Other mistake: Why did Merrimen have to show Donnie how to use a M4? Earlier in the movie it was stated that Donnie was in the Marines for a short time.
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.
Plot hole: The entire plot hinges on the villain's gang obtaining the tablet that allows admin access to the building's systems. However, it can only be unlocked via facial recognition and it is keyed only to Will Sawyer's face. In fact, when they finally do get it, Xia unlocks it by holding it up to Sawyer's face. So what was the point of trying to steal the backpack containing the tablet? Without Will to unlock it, the tablet is useless.
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)
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.
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.
Factual error: The country of Pakistan was shown to be part of the G12 summit member countries. But the G12 are Australia, Belgium, Canada, France, Germany, Italy, Japan, Netherlands, Spain, Sweden, Switzerland, the UK and USA. (13 countries, but the name was never changed when Switzerland joined in 1984).
Factual error: The repairman was freeing the soldiers from inside the locked gate using bolt cutters. The terrorist noticed this on the video feed so they electrified the fence, shocking the repairman. This would not have happened because the bolt cutters have plastic handles just for that reason, to keep you from being electrocuted by mistake. (00:54:50)
Continuity mistake: Near the start when Wade and Vanessa are discussing families, in most shots facing her she's got her thumb lying along his jawline, but in most shots facing him it's sticking up by his ear.
Continuity mistake: When the soldiers arrive at the Alamo, the soldier with the glasses is reading a book with a white cover. In the next shot, he is reading one with a red cover.
Continuity mistake: On the spaceship, Peter is talking to Tony, and has his hair swept back with gel or similar. When he says "You can't be a friendly neighbourhood Spider-Man if there's no neighbourhood", we cut to Tony then back, and Peter now has a fringe with no gel. In later shots it's back how it was before.
Continuity mistake: During the getaway in the 4-door olive-green BMW, in one shot, the driver's headrest is bent forward; in the next shot, it is shown back in the straight-up position.
Character mistake: During the opening raid of the FSB safe house, an operator is seen taking hard drives out of a safe. As he does, he states over the radio that they are "SSDs" (Solid State Drives), when in reality they are normal HDDs (Hard Disk Drives), which are noticeably larger than SSDs. (00:07:25)
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: When Elastigirl is chasing the high-speed train, as she is in the middle of making her second final jump to reach the train, if one were to look closely, the train actually drives right past her before she lands. (00:31:40)
Suggested correction: Only Big Nick and the other cops knew Donnie had served. They had his records pulled up. Donnie never told the other crew so he could look inexperienced enough to not run the whole show. It made it easier to double cross both sides later. Donnie played the fool to get the upper hand.
50 cent told Merrimen "he was a marine for a minute" also Donnie has an Eagle, Globe and Anchor tattoo (Marine Corps).
