Other mistake: Vers saves Fury, blowing a hole in the ceiling and somehow getting to the upper floor (why she does not blast holes for the remaining floors as well is unclear). They should be then at -4 from the -5 they were in, but they are shown ascending a flight of stairs, at the top of which Coulson lets them enter the door for level -4.
Other mistake: When Kylo/Ben leaves the Endor system to go to Exogol, he takes an old Imperial TIE Fighter he supposedly found in the Death Star remains. However, it is established in the previous films that that TIE fighters are short range fighters that are not equipped with a hyperdrive.
Other mistake: Vic and Stu get into a shoot out inside the animal hospital with some thugs, guns firing all over the place. The building is full of animals like dogs and cats and parrots. However, the animals stay completely calm and quiet during the entire gun fight and seem unaffected by the rapid, very loud banging of gun fire. Even right after it, a cat that just had it's tail stepped on sits on a dead body and meows like nothing happened. This is completely uncharacteristic of how animals would act to loud gunfire in an enclosed building, especially in a vet's. (00:45:00)
Other mistake: During one of the recording studio scenes, there's a short segment that shows a bunch of VU (audio level) meters close up. The very first meter in that sequence is not a VU meter. Its from of an old HF (High Frequency) Amateur Radio transceiver; The scale is marked for RF, SWR, and ALC. I'm suspecting that someone involved with the post production editing is a Ham.
Other mistake: Scott arrives in the park and sees hundreds of memorials listing people who were killed by Thanos. In the first close-up shot shown of one of the memorials, the name Norbert Lamey can be seen five rows from the top on the right hand side. The camera then pans to Scott walking in front of the memorial to the right of it. The name Norbert Lamey can be seen repeated on the opposite side of the memorial Scott stands in front of. (00:24:25)
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)
Other mistake: Deckard and Hattie were children at the same time, with Deckard appearing to be no more than 3 years older than Hattie. Although Jason Statham is presumably playing a character younger than he actually is, he is still noticeably much older than his on-screen sister. Jason Statham is in fact 21 years older than Vanessa Kirby.
Other mistake: The type of gas pump Danny used when gassing up the car requires the lever be moved from the on to off position before the hose can be placed back into the pump. It is already in the off position before he finishes.
Other mistake: At the start of the trench running scene where the soldiers charge, keep looking at the far left of the screen. You will see a small group of soldiers already running who were not in the trenches. In addition, they seem to be running without weapons.
Other mistake: In a city of millions and millions of inhabitants, when the protagonist chases his neighbour till she enters the building in William Street, the taxi that passes in front of him as he crosses the road is the same taxi with license plate T 9362 that nearly ran him over at the very beginning when he was trying to get his sign back. Which incidentally is a model of Chevy Caprice post-1981 (likely a 1987 Caprice). (00:02:25 - 00:24:35)
Other mistake: Despite taking place roughly 30 years after "X-Men: First Class," Xavier and Magneto have hardly even aged. Both would have been in their late 20's at the youngest in "First Class" and in this film neither looks any older than 40. It's not because of their mutant powers either - only Wolverine and Mystique were specifically mentioned as having a slower rate of aging because of their powers.
Other mistake: When the FBI returns their belongings to the apartment, they exit via the kitchen, where there is no door.
Other mistake: During the revelation of the second death, when the killer opens the toxicology report they just retrieved, the date is revealed; it says it was issued on 09/27/2018. But the events of the movie happen in November (it's Sunday 18th Nov when Marta wakes up with all the reporters at her door). It should also be noted that when a close-up of the report was shown earlier (when Ransom was looking at the anonymous letter brought by Marta) that copy had a big stamp in a corner saying 11-17-18, that in this copy is totally absent.
