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: 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: 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.
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)
Character mistake: The prosecuting attorney told William, "In the interests of getting this thug [Danny] off the streets as soon as possible, his attorney has agreed to plead guilty to assaulting an officer, possession with the intent to distribute, and resisting arrest, and that's all in addition to his parole violations. We're looking at five to seven [years in prison]." The parole violations alone are sufficient to get Danny off the streets immediately. (00:09:34)
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.
