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)
Factual error: Robert and Giselle have their belongings shipped to their new home at "18 Honey Bee Trail, Monroeville NY 10960." Monroeville is fictitious but the 10960 ZIP Code belongs to Nyack, New York. (00:00:04)
Continuity mistake: In the final battle, Lin Mi Sheng has her hair pinned up in a French twist. Her hair changes very frequently between shots and combat sequences. Sometimes it switches from a French twist to a slick chignon.
Continuity mistake: As the "lone wolf" escapes on the bike, there's a fancy swooping camera shot which tracks him, cutting to a shot from the front just as he scythes between two dark cars and past a police car. In that quick shot a woman suddenly appears cowering by the police car who wasn't there before.
Continuity mistake: At the end, the French soldier tries to kill Paul in the wet mud. When they finish struggling and spot the pistol on the floor, the mud on Paul's face is now dried and caked on.
Continuity mistake: When Sarah fires at the jeep chasing them she brings the weapon back in with the slide in the normal position, in the next shot it is in the locked back empty position. (01:26:50)
Continuity mistake: When Priscilla meets Elvis in Germany the position of the letters on the bed and of the papers scattered on the floor change positions between shots.
Continuity mistake: In a pivotal scene in the middle of the film, Josh and his stepmother Constance are having a conversation about how Lyle has helped Josh adapt to life in New York City. In the background, the same woman can be seen walking past them multiple times. She is wearing an open gray sweater with an orange shirt.
Factual error: A .22 shot would be 120-140 dB, muffled with a pillow down to 100-120 dB. Only one person heard the second shot? No one heard the third? Plus at the end there's no way a .22 could pass through a male chest cavity, and halfway into a female chest cavity - it's too low power.
Other mistake: Birdy's father whipped/flogged the palm of her right hand 10 times with a rod (or stick) yet she was able to hold a pen and write in her book with no sign of injury, pain, or even discomfort later that night. (00:28:12 - 00:29:24)
Continuity mistake: RJ got into his van and drove parallel to the house, almost reaching the end (right side) of the house when he saw Pearl in front of him and stopped. When RJ got out of his van, it was parked near the beginning (left side) of the house that he had already driven past. Also, Pearl was standing in front of a fence, so it didn't make sense that RJ would be driving straight toward a dead-end. (00:57:07)
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)
Suggested correction: And yet this very thing happens in real life. There are several cases of guards getting manipulated sexually, manipulated in general, or even killed by dangerous prisoners or mental patients. A part of this has to do with some guards getting in the business believing these people are misunderstood and that they can change them. As it happens in real life, there's no reason it can't happen in a movie. Movie characters aren't above real life mistakes.
Factual error: One of the warriors tells a trainee they move like a sloth, more than once. Sloths are only found in the "new world", not native to Africa.
Other mistake: When Jaeger is teaching Searcher how to throw. Through the scene Jaeger is handling Pando without gloves and Callisto is wearing fingerless gloves while also handling Pando. They should both have been shocked by the energy from the Pando. Jager is not immune, as he and Searcher are both shocked later by the Pando roots while using pickaxes to free the pando roots from the creature's heart later on in the movie.
Other mistake: The white horse looked very uncomfortable from what appeared to be an improperly placed bit (too far back and/or misaligned in its mouth). The handler should have noticed something was wrong and intervened. (00:20:30)
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)
Other mistake: Chris whacked Sky with a tactical-type axe over her right shoulder. It isn't clear if the tip of the talon blade actually made contact behind her shoulder, but the straight part of the blade apparently severed the top of her shoulder and Sky had to forcefully pull it out. However, there was no initial blood splatter, barely any visible blood on her, and she was able to fight and swing the axe, raising her right arm above her head as if it had not been injured. (01:19:35 - 01:24:09)
Continuity mistake: The straws in the three glasses in front of Abby are at different angles several times. (00:10:55)
Revealing mistake: A white truck could be seen in Tamra's rear window, following her car at varying distances. After Tamra hit Randall on his bike, the white truck was still there but gone when the camera returned to a front view of Tamra. Use of a green screen - the truck could not have gone past the accident or "disappeared." (00:03:35 - 00:04:10)
Factual error: The owl that JP was looking at made a "who who" sound. The owl may appear to be a Snowy Owl (one many people are familiar with), but it is a Barn Owl. Barn owls are not "true" owls and it is the true owls who "give a hoot." Barn owls don't hoot; they make a screeching or squealing sound which can be piercing (and eerie to some people). (00:32:50)
