Continuity mistake: When Buddy is lying in the roll-out bed in the living room of his father's house and asks to be tucked in, his father does so. His father comes back up and ends up having a red thread on his shirt. The shot switches to Buddy, then back to him and the thread is now on his right arm.

Factual error: It is impossible for a stream of burning jet fuel to follow a plane through snow and catch up. Not only is jet fuel extremely hard to ignite, almost as soon as the plane was off the ground the fuel stream would be too dispersed for the flame to climb up into the tank, and even if not it wouldn't burn fast enough to catch the plane.

Visible crew/equipment: When Mia and Brian are about to jump off the roof, when a gunman takes aim there's a cameraman to the bottom right below him. (00:32:35)

Factual error: The Siege of Syracuse occurred in 212 BC, during the Second Punic War, when Rome was still a republic. Some of the equipment the Romans are using in the movie, however, particularly their swords and helmets, are replicas of weapons dating to the later Imperial era.

Continuity mistake: As Captain America arrives in his car at the airport car park, he stops right next to the line dividing the spots. In the following shot, when he steps out, the car is further away from the line, more towards the center of the spot. (01:26:50)

Revealing mistake: When the Pterodactyl is flying around with the egg, its shadow isn't cast as she flies over the trees.

The Grinch: Those Whos are hard to frazzle, Max. But, we did our worst, and that's all that matters.

Factual error: When the fish tank has been cleaned by the newly installed laser fish cleaner, the machine states that the water temperature is '82°.' In Australia the Celsius scale is used; therefore, it should be about '28°.' Australia is 100% metric and has been since 1974! Nobody in Australia - nobody, anywhere, any time since 1974, uses imperial measures. There is absolutely no question of the dentist having an imperial thermometer or expressing himself in° Fahrenheit. It is actually illegal to import or sell any instrument using 'Imperial' scales. You couldn't buy a Fahrenheit thermometer if you tried. (01:14:30)

Other mistake: Before Uncle Owen yells for Luke, if you look very closely, a fly can be seen on the lens (best seen on the special edition release). The fly was removed in the 2019 release.

Trivia: In the scene where Anna is outside the gates during "For The First Time in Forever", you can see the backs of Flynn and Rapunzel from "Tangled".

Question: In the scene right when they leave the hotel after the wild night, they see Doug's mattress. Is there any significance to the guy that turns to them and says some people just can't handle Vegas?
