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: At the pleasure island before Lampwick gets into the wheel of fortune, he has his glass full of beer, then it is empty, then full again.
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)
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: 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 Riri Williams' dorm room, the number of braids hanging over her shoulder changes frequently while Riri and Shuri are talking.
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: 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)
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)
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.
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: It isn't clear whether Robert's gunshot wound was an "entrance" or "entrance and exit" and if the nurse or surgeon? wearing scrubs committed a character mistake - "We were worried, given how deep the bullet penetrated" but Sasha "heard the bullet passed through Robert's shoulder." "Penetrating" means the bullet entered but stayed inside the body; "Perforating" means the bullet passed through the body. In general, perforating gunshot wounds tend to be less serious and therefore less "worrisome." (00:06:23 - 00:07:42)
Factual error: The tank used by the German platoon is a Soviet T54/55, which didn't come into service until 1948, after the Lapland War had ended.
Deliberate mistake: The number of clicks (sounds) Christine made on the "text to talk" device did not match the total characters she typed. With few exceptions, there were a lot less clicks/sounds than there should have been based on the amount of letters/words she typed. (00:06:40 - 00:15:30)
Continuity mistake: In the very last scene when Bo is hugging Stanley before the game it reveals his "Never Back Down" tree tattoo on his lower left arm. Yet right after in the closing credits and presumably depicting that same game it showed his left arm after taking a shot with the tattoo removed.
Revealing mistake: Luke points a flashlight along the side of the staircase, but no shadows are produced on the wall from the vertical posts. Luke points the flashlight in front of himself and produces his shadow on the wall behind (and the shadow doesn't look like the way he is holding the flashlight). After Luke goes through the entryway aiming his flashlight ahead, a circle of light is behind him. The power is out, so the flashlight is the only light source - except that used for filming in the dark. (01:03:00 - 01:05:25)
