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)
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: 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: 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: 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: 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.
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.
Factual error: In the timelapse footage showing the street outside Bob's Restaurant, the shadows are moving in the wrong direction. In the northern hemisphere, shadows go clockwise. (00:13:46)
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.
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)
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)
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: 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)
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)
Continuity mistake: After Kath pulled up to the cabin, the position of her car changed. Kath drove parallel to the fence before turning to the right about 45° toward the front door, but when she got out of her car, its rear end was perpendicular to the fence. The angle of the shot of Al coming out the front door would also place Kath's car more pendicular to the cabin instead of at an angle, and parallel to the fence instead of at an angle. (00:05:39 - 00:06:36)
Factual error: Josephine walks away from her father King Louie 14th, after he tells her she has to marry the young Duke Lintillac for his money. When you look at back of Josephine, you can see a zipper in her skirt. King Louie 14th was King from 1643 until his death in 1715. The first zipper was invented was in 1851. The zipper being used as we know it present day was invented in the early 1890s by Whitcomb L. Judson. (00:55:57)
Revealing mistake: The $100 bills in the briefcase looked quite fake and were obviously a prop. (00:13:40)
Other mistake: When Tess says good night to Keith, the lights in the bedroom are on, but the switch is down (off position) but when she wakes up in the middle of the night, the lights are off and the switch is still down. We see a lamp on the same side as the switch but even if she turned it off manually, being plugged into that AC outlet would mean the lamp would probably be off based on the switch. If the switch was up in both shots, it would be different.
