Other mistake: Anna is shown from the front as she ascends an ice staircase inside Elsa's ice castle. There are giant ice pillars to Anna's right and left. They should reflect the side of her face, but instead the reflections show her face from the front.
Suggested correction: That's not how reflections work. The ice walls are about two feet to her side so the reflection would look like it was shot from the front but about 4 feet to the side.

Other mistake: In the flashback of Bruce Wayne getting killed, his mother is cradling his body and weeping. She has his blood all over her hand from touching his wound. She rakes her fingers across his shoulder and down his chest with her bloody fingers, leaving no trail of blood, but when she places that same bloody hand on her face it leaves blood all over her face and mouth.

Other mistake: In the hotel, the gang are putting together a list of suspects trying to figure out who the Phantom is. They mention 5 suspects, Chrissy's parents, Brick Pimiento, Mel Richmond, Dewey Ottoman, and Lotte. When they look at the list though, only 4 pictures are shown. Chrissy's parents are not there, yet they were the first to be mentioned. (00:25:35)
Other mistake: In the regional qualifier, there are five planes with better times than Dusty. Fonzerelli is disqualified. So... How come the other four that qualified don't show up in the big race?
Other mistake: The head of the animal that Guy is wearing when he first meets Eep is not positioned in a way that he would be able to see out of it when he holds his hands up to defend himself.
