Continuity mistake: After Sandler shaves in the cabin he gets back on the deck unshaved. When they appear at the dinner he is shaved.
Continuity mistake: Red is barefoot for a long period in the movie, but when they run to the boat she's wearing barely-visible slippers, presumably to protect her feet while running outside.
Continuity mistake: After the beast and David break the window and fall down they do so beside each other, but when they hit the ground they are separated by several feet.
Continuity mistake: After we first meet Grimmel, there's a scene where a dragon charges him before he puts it to sleep. The view from under the dragon's feet show him getting very close to Grimmel but when the angle changes suddenly he's much further back before he's shot.
Factual error: When they first get attacked in the mini van, the side windows crack and get scratches. (You can see the "spider webbing"). A side window shatters in small pieces when they crack slightly.
Revealing mistake: The film was rushed to theaters, leaving a few mistakes which Universal fixed. In the original cut, toward the end, Judi Dench's human hand is visible, complete with her wedding ring. This was fixed for the re-release.
Continuity mistake: When Anna's singing "The next right thing" she puts a bag on her shoulder, with the strap on top of her hair. After the camera spins round her, her hair is suddenly on top of the strap. This bears a strong similarity to the mistake in the original Frozen where Elsa's hair passes through her shoulder - might be a deliberate nod, or else animating hair around objects is difficult enough that shortcuts are often taken.
Factual error: Dr. Fielding is dead inside the JPL building. His blood is dripping onto a telegraph key and it is sending perfectly comprehensive Morse Code. The blood drips are too random to do that. (01:13:25)
Suggested correction: It's clear he was alive at one point, and the way he has positioned shows he was probably already sending that. There was a break from him sending it, and it's clear the kids didn't understand the morse code, which could be the point his blood was dripping.
That could be. OK.
Visible crew/equipment: Opening sequence, Noomi Rapace kills all three terrorists who have arrived by truck, commandeers their truck and loads her two clients into it to transport them out of danger. As she drives away, we see a bare arm, hand and rolled up dress shirt of a person standing in the back of the "empty" truck. (00:05:05)
Revealing mistake: On the way to the border, after Gabrielle has died, when the camera pans it on her face, you can see her eyelids shift and blink.
Factual error: With a number of flowers blooming, the movie appears take place in spring. There are many scenes of central park with flowering trees and shrubs in full bloom. However, the yellow blooming shrubs called forsythia do not bloom at the same time as the flowering cherry trees. Forsythias bloom about a month earlier than cherries and are usually the first items to bloom in spring.
Continuity mistake: Dr. Stone mentions there is an emergency exit below the landing pad. He then asks the pilot if there is a camera underneath. In this shot, the pilot has his eyes partly closed and his lips pursed together. It cuts to a close up of him and suddenly his expression is different, with his eyes wider open and his mouth open. (00:19:50)
Continuity mistake: En route from the front door of Wayne's mansion to the table in the Batcave, the pile of pizza boxes in Alfred and then in Mike's hands continues to change in size and number: at first the pizza girl delivers 11 boxes, Mike slams on the table just 8, but he brought down the stairs twice that amount (without counting through freeze-frame the precise numbers, it's simply obvious at first glance that the pile is bigger in some shots and the pizzas themselves are pictured of inconsistent size).
Other mistake: The ex-husband makes out a check for $108,000 at the start of 2020 when Kate returns from Africa after Christmas, but it is dated 3/18/2019. (01:12:06)
Other mistake: While in the pool room, Zoey falls off the wall onto a portion of floor that hasn't collapsed yet and loses consciousness. This area is next to the section of floor that collapsed first. Jason jumps down to help Zoey. As he is helping her up, and onto the wall, that section of floor collapses, forcing him to grab the wall to avoid falling 20-ish stories with the floor. As he looks down drop, the section of floor that fell first is amazingly back intact. (00:59:20)
Continuity mistake: Ben caught his T-shirt in his right hand when the girl threw it to him in the swimming pool, but Ben is with his empty right hand in the pool. When Ben got out of the pool, he picked up his T-shirt. (00:32:18)
Factual error: As well as the sergeant's stripes on his cuff, Sergeant O'Neil wears three pips on his epaulettes, which would indicate a much more senior rank and would not be worn together with the stripes.
Continuity mistake: When Ana finally escapes in Peter's truck, the truck is a Nissan Frontier extended cab with a long bed, no tonneau cover and no roof rack, but shortly after they show her crossing a bridge in a Frontier crew cab (4 door) short bed with a tonneau cover and a roof rack. It is also has dirt on the side that looks like road salt whereas the original truck was very clean. (01:16:00)
Continuity mistake: Right after the scene where Nels saws up his gun, he walks into a store with his arms folded. His hands are down close to his stomach. When it cuts to the next angle, they are much higher at his chest. (00:26:51)
