Continuity mistake: Near the start, Mirabel is given a basket with items such as bucket and spade, windmils etc. When given the basket the buckets are towards her. When the shot changes the buckets are away from her. (00:07:15)
Plot hole: Johnny's dad jumps in his truck and gets to Johnny in moments. That same journey was shown to be an overnight bus journey for everyone else.
Factual error: When Cruella first drives her iconic car, being in Britain the driver's seat should be on the right side, not the left.
Suggested correction: Cars can be imported from overseas. It's very possible the car was imported from America.
Character mistake: When Tim and Ted enter the school, we can hear a group of girls including Tabitha singing: "The wheels on the bus go Pi-r-squared / circumference all around." But π r² equals the area of a circle, not the circumference (which is 2πr). (00:36:34)
Continuity mistake: While at Dino Stop, Katie convinces her dad not to play it safe and to take a chance to save the world. Rick agrees and extends his left hand for the "all hands, Mitchell family on three." In the closeup we see Katie put in her right hand, but in the wide shot Katie's left hand pulls out. Also, note that in the closeup both Katie's and Aaron's positions between their parents are switched. (00:45:00)
Factual error: Dwayne Johnson is pursuing a thief. He gets into a Porsche Taycan and pushed the start button, and he can drive off. But you have to have the key fob in your pocket or bag. Porsche explains: "As long as your key is close when you grab the door handle, the system automatically checks the encrypted access code on the key. Once your code is validated, the door will unlock, and you'll be granted access to your vehicle." Dwayne had no fob, as the car was just parked.
Suggested correction: I assumed the car belonged to the guy who was stood just in front of it, so the fob would have been in his pocket, close enough to start it.
Maybe start it, but since he drove away, the fob would no longer be in his possession and although the car would continue running one time, it could not be restarted.
Maybe the owner was so stupid to leave the keys in the car. "Who can steal it, here in front of me?"
Revealing mistake: The jaguar near the start jumps onto the bar and prowls along it. It knocks over one glass with some force, which shatters, but the second glass is barely tapped by its foot and it smashes to bits too, when it should just have been pushed out of the way.
Continuity mistake: While Semmi is telling Akeem about their visits to the nightclubs, there are shots from the original movie with some women they meet. When the "woman" in red tells them she's going to tear them apart, Semmi's wearing a patterned shirt, tie, and blazer when he spits his drink. Two shots later (new footage), Semmi's shirt collar style changes, as well as the pattern on his shirt and blazer. (00:11:15)
Continuity mistake: When watching the water retreat after Sisu falls, a view from behind the characters shows Noi sitting on Tuk Tuk. The very next cut shows Tong picking her up from the ground. (01:18:01)
Continuity mistake: When Mrs. Krementz talks with Zeffirelli while he's taking a bath and asks her to close the bathtub curtain, the cigarette he previously had in the mouth disappears in the next shot when Mrs. Krementz closes the curtain.
Continuity mistake: Leonardo DiCaprio's phone is shown attached to his car dashboard. He gets out of his car, all the while, looking up toward the sky. The next scene shows him grabbing his phone from his pocket while standing outside his car. (01:36:06 - 01:36:56)
Factual error: Unless left in the vehicle (not the case here), towed impounded vehicles do not have keys. Moreover, lacking keys, a valid registration, possibly proof of insurance, and new plates, vehicles bought at a NYPD auction are to be TOWED away. A newly-purchased auctioned vehicle, such as the Navigator in the movie, is "ticket-" or "citation-ready", not ready to be driven on the streets.
Continuity mistake: At the beginning of the movie, the real estate agent greets the McKenzies, lovers of all things open. The potential clients hold the papers in a completely different way at the cut ("I was just telling the Breckins that..." etc). (00:01:15)
Factual error: During the escape from the farmers market a red London bus is in the background. Those busses aren't used in Gloucester.
Revealing mistake: When Julie is running around the city whilst all the extras are stood frozen, there is a moment where she is walking next to a small park, before beginning to turn right and run down a road. Once she runs onto the sidewalk after running down the road, two girls can be seen stood on the same sidewalk holding hands. The girl on the right can be seen moving her right hand ever so briefly, even though the extras are all supposed to be standing completely still. (00:54:35)
Factual error: The Black Watch sergeant major wears a crown over three chevrons, which was the correct rank badge for a company sergeant major until 1915. However, this is at least 1916 (as conscription has started and the men are wearing steel helmets, both introduced in 1916). CSMs had been redesignated as warrant officers in 1915 and now wore a crown on the lower sleeves instead.
Continuity mistake: The amount of red beverage in June's bottle changes several times, from up to the curved part of the plastic bottle (lower amount) to below the neck and up to the neck (almost full). Front views of Mikey show the level of the drink higher than views toward June. (00:17:07 - 00:18:51)
Revealing mistake: When Archie swung the fire extinguisher in front of the woman, it did not look like the fire extinguisher was close enough to strike the woman's body, let alone knock her out. Also, when Archie came out and closed the door, he would have been walking where the woman's body was on the floor. (00:34:05)
Continuity mistake: Rudy looks at the candy cane, which is broken off at the handle/arc. Rudy sucks on the candy cane while he talks to his mum on the phone. When Rudy removes the candy cane from his mouth, the curved part is longer than when he first puts it in his mouth. (00:08:40)
Revealing mistake: During one of the chase scenes, an SUV hits a rock barrier and flips over landing on its top. The car spins around, and we see that it is empty. The driver then climbs out as if he was just in the vehicle.
