Visible crew/equipment: When Tom and Sonic pull over and the mini drone explodes, knocking Sonic unconscious, the camera pans away and you can see emergency vehicles blocking the road on the right of the screen, presumably closing down the road for filming. (00:59:55)
Plot hole: Scar tells the pack he didn't make it to the gorge in time to help Mufasa. However Zazu was with them at at the gorge. He could have easily told Serabi or any of the other lions on the numerous times he spoke with them, exposing Scar.
Suggested correction: Actually, Zazu wouldn't honestly say that Scar was lying; he left Scar at the gorge, but for all he knows, when Scar talks about not getting to the gorge in time, Scar could just mean that he couldn't find a safe path into the gorge to help Mufasa and Simba escape.
So Scar would say he couldn't get to Mufasa in time. Not the gorge.
Other mistake: When Jessie pops the tire on the RV, Bonnie's dad gets upset and says "I just bought it." Throughout the rest of the film however, he says the RV is a rental.
Suggested correction: Not exactly a mistake considering he bought a rental.
That's a self-contradicting statement. Buying something means you have ownership of it. Renting something means you pay for its use with the understanding that it will be returned at a specified time. You can't buy a rental any more than you can rent something you buy.
Suggested correction: At best it's a character mistake. As he was exasperated as Bonnie's mother says to her "Daddy's going to use some words" apparently meaning he was going to swear.
If it's a character mistake, it's still a mistake, so no correction is needed. I think it's a valid other mistake because it's the screen writers flipping back between owning and renting, but not an actual plot hole. I've been exasperated with a rental before and never in my anger or frustration said I bought the rented item.
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.
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.
Continuity mistake: Batman enters Lex Luthor's room at night while he's sleeping, and completely casts a shadow over Lex. This wakes Lex up and he sits up. Batman has not moved from his position, but now in the next shots he is no longer casting a shadow on Lex's bed or body. (00:24:47)
Continuity mistake: When Lance is telling the guard at the start that he's going to throw his gun to the snowman behind them, the snowman that is there was not there in a previous shot and appeared from nothing.
Continuity mistake: When Ash and friends are entering the wharf, there are two people that change between scenes. There is also a person who goes from having his right hand in his lap to having it scratching his head. (00:23:06)
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: The two cucumber slices that Jesper puts in the palm of the Drill Sergeant change position between shots - in particular, in the close-up with Jesper walking away and putting the teacup in his hand as well, the two slices are side by side, while they are instead one on top of the other before and after. (00:02:25)
Other mistake: When the characters go to the Himalayas, the whole time, like for 20 mins, including the confrontation scene, they are all wearing casual, short-sleeved shirts. You can see Mr. Burnish's henchmen wearing winter clothing, while the main characters don't freeze to death. They only start getting cold after a long time.
Factual error: Towards the end of the movie when Superman and Henshaw are fighting on the Watch Tower in space, Lois hits the sun shades to lower them so that direct sunlight can hit Superman and power him up. This is out in space with no atmosphere to filter the sunlight. The reason the blockers were there was for this reason, to keep the harmful unfiltered sun light from hitting people on the ship through the windows. However, she is able to stand there in the direct light after it's done and kiss and hold Superman without being hurt or burned by the intense direct unfiltered sunlight or its radiation.
Continuity mistake: After the alien abduction, Emmet plans to lead a rescue mission and opens the gate asking "Who's coming with me?" During the sequence, the shadows change completely. At first he is not casting much of a shadow, then it reaches the metal doors, then it stops midway towards it. (00:20:55)
Factual error: A blunderbuss is fired at a safe. The shot not only bores a hole into the safe but also blasts it out of the window behind it. First, a gun can do no such thing; a cannon can. (The film already establishes that the safe is incredibly heavy.) Second, the hole on the safe is wrong. It is gouged outward as if by an explosion from within. (00:38:10)
Continuity mistake: In the sequence with the pigeon that tries to topple the severed hand off the gutter, twigs are right next to its fingers or not, depending from the angle. (00:06:35)
Continuity mistake: Scooby and Shaggy are lying face down on the massage table when the zombies arrive. Shaggy has his robe lowered baring the upper back, but in the close-ups you can still see the robe up covering his shoulders perfectly. (00:28:00)
Continuity mistake: The protagonists escaped from captivity and managed to return to Harry's palace. Luka decides to leave to go look for his mother. Harry seems to send him off, and he is standing in the middle of the stairs, about 4 steps below the guard. Harry at this point is in close-up; the guard is not visible, and at the next cut somehow Harry shoves him off as if he were standing directly behind him. (00:16:00)
