Character mistake: The Admiral refers to Top Gun as Maverick's final post. As Maverick is a Naval aviator, it should be referred to as his final duty station. The army uses the term post.
Suggested correction: "Post", in the Navy, is also used in the same manner as "adjourned" or "dismissed". It could be argued that the Admiral was stating this is the last duty station from which he will "post".
Character mistake: While discussing his squad providing air support for the Marines on the ground, Lt. Cmdr. Cevoli refers to the men as "soldiers." Marines are not called "soldiers" because they are not in the Army. It is common for a layperson to make this error but nobody in the U.S. Navy would do this.
Character mistake: Danny told Vincent, "Lab just came back on the pills. Donepezil. Alzheimer's drug. Your shooter's losing his shit." It was too early in the investigation to conclude that the drug belonged to "the shooter." There could have been a witness who ran, an accomplice, or even just a coincidence that someone not involved had dropped his pills. It would be up to the investigators to determine if the prescription bottle belonged to a suspect or "person of interest." (00:55:27)
Character mistake: Towards the end of the movie when the Giganotosaurus is attacking the group and Claire gets the rope wrapped around her leg and pulled towards the dinosaur Owen actually shouts Bryce before saving her instead of Claire.
Character mistake: The handler tells ladybug that there are 10 economy and 6 first class carriages but when ladybug is trying to calculate the chances of finding the briefcase he starts with saying 6 economy carriages. (00:07:24 - 00:10:22)
Character mistake: The patrol officer who stopped Will for speeding fired two warning shots in the air when Will ran. Patrol officers should not (and generally do not) fire "warning shots." (00:49:57)
Character mistake: After Robyn asked Mason who Bud was, Mason said, "Bud was Paul and I's staff sergeant in Afghanistan." [Sic] FBI agents have at least a BA/BS and often advanced (graduate) °. Mason's use of "I's" is not proper and reflects his failure to master basic English. The possessive pronoun of "I" is "my", so Mason should have said "Paul's and my..." (01:35:16)
Character mistake: Nolan said, "Everybody knows that no sharks swim in freshwater" and Spencer said, "They don't come into freshwater", but there are freshwater sharks (e.g, river sharks) and bull sharks (not true freshwater sharks) can survive in saltwater or freshwater. Jacob Harper (National Aquarium) pointed out eyewitness accounts of sharks swimming up the Mississippi River and "bull sharks have kidneys that recycle salt" but did not mention the glands near their tails that help keep salt in their bodies. (00:08:08 - 00:29:50)
Character mistake: "Joker" announced, "we get out of our cages once a week for one reason only. And that is, The Dungeon [where the fights are held]." The cells were in PODS, where the inmates hung out. Inmates had work assignments around the prison and walked the halls. There were outdoor exercize areas with gym equipment and basketball hoops. There was a pool table, games, TV screens, a common cafeteria, etc. - far from "getting out of cages once a week." (00:36:50)
Character mistake: Near the ending of the movie, when Aatami slips with his pickaxe under the plane, they hear a noise inside the plane and ignore the noise by saying it's just an old plane. The DC-3 was actually only 8 years old and still in production by the time setting of the movie, which doesn't make it really that old. (01:13:23)
Character mistake: Doctor Bancroft mispronounces "Nobel" when reading the headlines to Michael. She pronounces as "noble." It's a famous award, especially in the field of science and someone as smart as she is suppose up be would know how to say the name.
Suggested correction: Honestly, I just rewatched the scene in question, and I really wouldn't consider that a character mistake. It's not a super egregious mispronunciation to begin with (the difference between the sound of the words is quite minor), and based on the way she speaks and the fact she has a bit of an accent, it just seems like more of a personal affectation than a character mistake.
Character mistake: After Travis confronted FBI Director Gabriel Robinson (killings and telling him to go public about Operation Unity), Gabriel said, "I am the director of the most powerful organization in the world." There may be interpretational issues regarding the meaning of "power" and what constitutes an organization (versus corporation, law enforcement agency, company, etc.), but the FBI is NOT the most powerful organization in the WORLD (the U.N. is?) and probably not even within the U.S. (01:31:50)
