Factual error: No matter how sophisticated the STEM chip is, it would not enable Grey (Logan Marshall-Green) to go from a completely horizontal position to a completely vertical position in one fluid motion, without bending his knees, and he does this several times in the film.
Continuity mistake: During the fight, a stop sign is ripped off a bus and thrown to the ground. It disappears in the next shot.
Other mistake: The private investigator has a full size Glock. The Glock 21 which is a .45 ACP has the lowest magazine capacity of 13 rounds. The 9mm capacity for the Glock 17 is 17 rounds. The PI exchanges gun fire and after he fires 7 rounds, his gun runs dry. Makes no sense to bring a half empty gun to a fight, plus he just got it back from his brother-in-law. (01:05:00 - 01:06:00)
Continuity mistake: The team has to come up with a plan to handle The Truth. Destiny's friend Willow stands up and says "So look, here's my plan." Destiny announces she has a better one; during this exchange, the phone in Cristine Prosperi's hand switches hands. (00:11:30)
Factual error: When the bank robbers pull the money out of the vault, they claim all the cash is from 1982. Yet most of the bills have large faces, which was introduced into rotation in 1996.
Continuity mistake: While Jim is narrating his story, he gets to the point when his son was hit by a drunk driver. The line slows down, but when it cuts to a close-up of Renée Zellweger saying "Sorry Jim", you see the trays shift. Only, they are back in the exact same spot as before when the close-up is over. (00:28:20)
Factual error: When Willie is taken from the hospital to appear in a criminal lineup, he is wearing a special watch he received for his birthday. When you are admitted into the hospital, the first thing you have to remove is a watch and/or jewelry.
Factual error: Since the movie was set in the 60s, David Senak couldn't have gotten in trouble for shooting the man running away. In the 60s, the police could legally shoot any criminal running away. This didn't change until Tennessee v. Garner in 1985.
Continuity mistake: The candle to the far right in the candelabra is tilted to the right to various degrees or not in between shots. (The other candles aren't exactly straight up.) In one shot, the candles are further apart (not paced the same distance between them). The top half of the candelabra was tilted to the right when the right candle was leaning against the wall. (00:24:27 - 00:25:20)
Continuity mistake: At the beginning of the movie, Regina is looking at pictures and messages on her phone. There's no solid continuity between close-ups and wider shots, with the hand position changing suddenly most times. (00:01:10)
Continuity mistake: At the beginning of the movie, Cass is blackmailing Mira about the true nature of her little trip. She calls Liam up; during the scene, she is holding the hanger in a different way between shots (left hand on the hook, or under it). (00:04:00)
Continuity mistake: Kate at the beginning of the movie asks Demerius, the kid who is reading a manga, to read some of it loudly for the whole class. When she addresses him first, the book on his desk changes position between shots, repeatedly. (00:01:20)
Continuity mistake: When the soup is about to be served, you see the horns blowing to introduce Victoria, and you can see all of the footmen lined up already with trays of soup, but in the next shot, it shows that they are just starting to march in to line up with their trays of soup. (00:10:45)
Deliberate mistake: The front passenger's side mirror [driver's side is on the right] is parallel to the screen/camera yet there is a perfectly clear image of the passenger's face looking into the mirror. (00:00:38)
Continuity mistake: Izzy gets out of the car of her one night stand and lights up a cigarette. She begins to type on her phone, phone in the left, cig in the right. A jogger bumps her and in the next shot she coughs on purpose to try and make her put the cigarette out. From now on, Izzy's phone is in her right hand and her cigarette in her left hand. (00:08:05)
Continuity mistake: Lynn Jackson collects things from the desk and looks at George Pierce, who tells her "I'll talk to him", clutching his smartphone to his chest. Next shot and his arm is down his side. (00:18:10)
Continuity mistake: Priscila carries Helen's bag while she gets her seat. She gives her the bag using her left, while she keeps her own in her right hand. Cut, and Pauline Collins is turning around passing her bag from the left hand to the right. (00:07:40)
Factual error: In the beginning of the movie, during Dickens' visit to America, you can hear them playing the melody from the song "I'm a Yankee Doodle Dandy" written by George M. Cohan in 1904. This was 61 years after the events in the movie. In the ending credits they cite this as "Yankee Doodle Dandy" which was written many years before. But, that was not the melody that was being played.
Continuity mistake: When the weather balloon is launched, the kids are alternately in the sun or shade depending on the camera angle.
Continuity mistake: Michele Riondino has just killed the snitch and is going after the witness, a Chinese woman. He holds her at gunpoint; she does not move, but in a shot she has hair in front of just her left shoulder, both shoulders in the next. (00:30:30)
