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: On the train Otto says a 1964 quarter is pure silver. They are actually 90% silver and 10% copper. (00:30:28)
Suggested correction: Most people wouldn't know the chemical make-up of a quarter prior to 1965. They'd just refer to it as a silver quarter, not realizing it's partially comprised of copper.
Character mistake: Gru doesn't recognize Nefario at the record shop, despite meeting him at Villain Con in the Minions movie. And given the fact that he can recognize all of his Minions without even asking them who they are, he should definitely remember seeing Dr. Nefario.
Character mistake: The 911 operator told Margot, "He [intruder Griffin] sounds harmless to me" and Margot said, "Fine", ending the 911 call. The 911 operator should follow protocol for an intruder (especially since there was the possibility of a another intruder in the house), not make a subjective assessment of the situation based on the conversation between the resident and the intruder. (00:30:15)
Character mistake: After the math club students, in unison, cited pi to 3.141592, Percy continued with "65839" - but only the "65" are correct. He should have said "65358..." before being cut off (or "65359" if he was rounding up the last "89793238"). Even though the movie is classified as a comedy, Percy was showing off, but he was wrong. Charlie, Math Club Advisor, also committed a mistake because he stopped Percy by saying "Percy, we got it. Good" (as though Percy was correct). (00:04:29)
Character mistake: Lawyer Tom was in the bar when locals were speculating that Kya killed Chase. He told Kya that people in Barkley Cove call her "Marsh Girl" and "When you stand trial, you will be judged by a jury of your peers from Barkley Cove." In the courtroom, people were shouting "She's guilty" and "We all know she's guilty." The judge pounded his gavel and said, "We will now begin jury selection." Tom and/or the judge should have filed a "Motion for Change of Venue" to ensure a fair and unbiased trial. (00:10:23 - 00:29:44)
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: After Dimitri put Leena's wrist bands on for her (through the door slot), Leena said, "I want to do something nice for you; you can come in." Dimitri agreed, and Leena pulled up a chair to stand on (to be his height) and caress his face/ hair. When Leena bent in to kiss him, she banged his head against the wall several times, killing him. As a "Saarne Instituute" security member, Dimitri should know not to get sexually involved with or trust a patient, especially the most dangerous one. (00:10:29 - 00:11:29)
Character mistake: Laura is on the floor, screaming and exhibiting bizarre behaviour, so Dr. Rose Cotter goes to the wall phone to call for help. Instead of maintaining observation and continuing an evaluation of Laura, the psychiatrist faces the wall while making the call and even stares at the wall for a couple of seconds after hanging up. A patient's body language can/do help make a diagnosis, so the psychiatrist should keep her eyes on Laura. (00:11:20)
Character mistake: When Pinocchio goes outside and sees the sun for the first time, Geppetto explains, "The sun goes around the earth once a day." That is wrong. The earth revolves around the sun.
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: Miles is playing on the beach a tune that Birdie Jay recognizes instantly as Blackbird by the Beatles, and Miles flexes saying that it's the exact guitar Paul wrote it on. That'd be difficult though, since it's a right handed guitar, and McCartney plays left handed (albeit he can play right handed too). You could argue that this is one of the hints that Miles is not very smart. (00:20:00)
Character mistake: Erin, a nurse, looked at Jason's bruise in the woods and said, "It's really hard to tell what it is. I mean, could be internal bleeding." Technically, ALL bruises are caused by internal bleeding (but the bleeding doesn't break through the skin). A nurse should know the possible signs/symptoms of internal bleeding (the serious type), such as nausea, vomiting, dizziness, loss of balance, change in vision, low blood pressure, etc. and the nurse should have at least checked for a rapid heartbeat. (00:49:20)
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: 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 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: "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: At prom, when the choir girls sing "don't stop," the girl on the far right can't help staring at the camera twice.
