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.
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: 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: When Sister Irene's habit is ripped at the back, you can see a bra strap on her left shoulder which disappears when she is seen at the front and when the camera is closer to her back (when she has the pentagram carved into her).
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: 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: 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.
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)
Visible crew/equipment: Thomasin McKenzie is searching her father in the woods. In that scene a crew member is visible behind a tree. (01:15:00)
Factual error: When the order is given to activate the US Navy 6th Fleet, the warships are shown with their crews standing on deck in their dress white uniforms, which is only done when pulling in or out for a deployment, or ceremonial port call (fleet week). (01:33:00)
Factual error: The opening scene shows Donna graduating from New College in 1979. That is not possible, women were only first admitted in 1979.
Factual error: Towards the end of the movie when Ally is in her hallway looking at Jack's old concert tour posters hanging on the wall, the poster closest to the camera says "Washington State Fair" and a 2011 date. Unfortunately, that fair did not get that name until 2013. Before that, it was called "The Puyallup Fair" (officially named the "Western Washington Fair"). Locals still call it "The Puyallup Fair" to this day.
Continuity mistake: Nick proposes on the plane and puts the ring on. They kiss and you see both of Rachel's hands and there is no ring on her finger.
Continuity mistake: When Ana and Christian are having sex on the dining room table, she drops Christian's pants below his butt. Scene cuts and Christian's back is shown, with his pants above his butt. Then cuts back and they're below again. (00:54:40 - 00:56:50)
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: When Kate is hanging on to the sleigh as it takes off she is holding on with one hand. Camera changes and now she is holding on with both.
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.
