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.
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)
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)
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)
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 Alana is walking toward the students, the hedges are mostly dark green, sheared level across the top, and reach to her elbows. Later (after Gary tells Alana he will take a mirror), the hedges turn mostly yellow and flower-like across the top, are quite uneven, and are as high as her shoulders in spots. (Use of a green screen is apparent). (00:00:40 - 00:01:26)
Suggested correction: One look at the scene make it apparent this entry is totally incorrect. The bushes look natural. The yellowness is just colour grading. There is no sign of green screen usage whatsoever. It would make no sense for this film, especially if you realise that director PT Anderson is known to be very much against the use of any sort of VFX or green screening.
Revealing mistake: When "Snowball" is sleeping on Lena's bed, it is obviously a "stuffed double" (stand-in). Snowball is usually partially hidden behind the dog (so breathing doesn't need to be shown/mimicked). The failure of Snowball to make even a slight movement is a giveaway (e.g, no ear movement when Lena starts talking), but even the stuffed lion, in itself, is not a very good replica - it simply looks fake. (00:33:44 - 00:48:20)
Factual error: Morse code is supposedly being transmitted by the blinking street lights. They supposedly spell "For 3veryth5h1ng that 7iv3s is holy." I know Morse code. It was just a random scattering of letters. (01:00:05)
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)
Continuity mistake: Max Cameron's classroom appears to be slapped together and inconsistent. The wall is white but later tan. The door hinges are on the right, then left. The pencil sharpener, awkwardly mounted on the door frame, gets moved to the right. The hallway is a tan wall, but later just a closed door. Doors comprise the wall behind Dewey and there's a door behind Max, to the right of the white board. (00:59:55 - 01:00:43)
Continuity mistake: When Tom knocks down the bike at the car, the position of the fallen clothes changes between shots.
Revealing mistake: When Jake is sliding on the floor at the mall trying to grab his retainer, streak marks are visible on the floor from where they practised the shot.
Continuity mistake: At the Internet Store, Spencer was told his house was "right outside" the service area, internet was not available, and a satellite would not work. At the Phone Store, Chad told Lynn and Zoe they were in the "dead zone." When Lynn answered Spencer's call by putting her head out the upstairs window, she said, "The service is great up here." Lynn and Zoe could listen to the news on their cell phone in the kitchen and Zoe read about asteroids just outside the front door. Internet worked? (00:04:53 - 00:28:00)
