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)
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: When Booth is caught with the egg at his house, Hartley gives a "I know who you really are" speech to him and during this time, he's drinking from a clear glass. He hands Booth the glass as he is walking around. Immediately after handing Booth the glass, you can see Hartley has another glass. Then takes the glass from booth shortly after. (00:17:03)
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.
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: 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: 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)
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: 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)
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.
Continuity mistake: The angle of the laptop on the kitchen table changed (and no-one was close enough to have moved it). The laptop was initially more evenly aligned with the edge of the (round) table. A little later, the laptop was not visible, but probably should have been. (00:04:09 - 00:04:44)
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)
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)
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)
Plot hole: Kyle got a flat tire and there was no cell phone reception to call for help, so he and Julia decided to walk to the Ghost Town. However, almost all vehicles - especially a relatively new SUV like Kyle's - have a spare tire. Kyle surely had a spare and could have at least tried to change the tire himself. (When Kyle saw his damaged tire, he complained that it was a $300 loss, not that he did not have a spare tire with him). (00:04:55)
Continuity mistake: Chris had strands of his bangs hanging down on his forehead but not a second later when the camera panned to a wider view to include all the group of employees. (00:30:44)
