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: 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: 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: 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: 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: 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: 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: 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: 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: 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: We see the lead driving on the motorway to get to the cottage. She leaves at junction 6 for Princes Risborough. Which means she is on the M40 that goes to Birmingham. When she arrives the host asks about the drive down and mentions the M4. This is a different road entirely, that goes to Swansea.
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: 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: 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 Predator is jumping through trees, then landing in a creek, splashing in the water. Its cloak barely flashes for a moment, then it can walk through the water still cloaked. This is a prequel to the other Predator movies, where it is already established that with their cloaking technology, even in the future, walking in water or getting wet disrupts the cloak and it malfunctions. (00:37:10)
Suggested correction: Even though Prey takes place 300 years before the original movie, its technology isn't necessarily "worse"; it's just different. In the 1987 film, the "Jungle Hunter" has a blue-tinted cloak that shorts out in the river. In Prey, the Feral Predator has a reddish/orange-tinted cloak. Fans suggest the red cloak might be an older, more robust (but perhaps less "clean" looking) version of the technology that wasn't yet sensitive to moisture but lacked the optical clarity of the later models.
While that is a plausible explanation, without concrete proof or a given explanation in the film or subsequent adjacent material, it still leaves it as an inconsistency in the movies. With all the other tech and weapons this predator has, being more primitive, and their species and culture taking any advantage they can in a hunt, it also doesn't make sense for them to use a cloak in the future with "more advanced tech" that is weak to water, when Earth is covered in water and it rains.
Character mistake: Sam told Tyler, "I work 36-hour shifts, so no time for friends or relationships." There might not be Federal regulations restricting the number of hours a nurse may work in a given 24-hour (or 7-day) period, but nurses have to maintain standards of duty/care and working too many consecutive hours would jeopardize her patients. It is recommended that nurses do not work more than 12.5 hours a day or more than three consecutive DAYS of 12-hour shifts. This gives 4 days OFF for relationships. (00:26:50)
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: Captor put a bomb under Orlando's desk chair and told him to hack into the bank and transfer $2 million into an account. Orlando responded, "If I get caught, I'm facing 20 [years in prison]." Captor's death threats to Orlando and his family members plus the actual bomb under Orlando's chair are more than enough proof of duress or coercion - legal defenses to engaging in a crime. Orlando would not be facing any prison time or criminal penalties after a legal defense was successfully raised. (00:20:07 - 00:23:20)
