Factual error: The size of the shadow of an object depends upon its distance from the light source, not the surface it falls upon. Lifting the cutout of the bird a few inches closer to the sun as they do would make absolutely no difference to the size of its shadow, yet it quadruples in size.
Factual error: During The "What A Day In London" sequence, William Shakespeare is seen reading his line "to be or not to be" from his play Hamlet. Pocahontas did sail to London in 1616, but Shakespeare died on April 23rd 1616, when Pocahontas arrived on June 12th 1616.
Factual error: During the plague when the fire and rocks are falling from the sky, they fall behind a statue of Rameses and are seen through its hollow eye holes. It makes for a great image, but that would mean that the statue's eyes were punched out like a mask, even though before they were just carved into the stone.
Factual error: Near the end of the song "One Of Us" when Kovu is exiled, the beisa oryx at the front of the animal chorus (the one shaking her head slowly) has incorrect facial markings for her species. The other beisa oryx in the background has the correct markings. When she sings "He is not one of us," solo, she has correct facial markings, but lacks the correct leg markings, which she had when her facial markings were incorrect.
Factual error: During the morning training session, Shang shot an arrow to the top of the pole so his soldiers can get it, but the arrow is stuck in a horizontal position. A difficult position to achieve, for someone shooting an arrow from below. Even if the arrow hit the pole at such a point in its arc, its kinetic energy would be at its weakest, preventing it from boring into the pole.
Factual error: When New Island's reflection is in a window on Giovanni's helicopter, it is not reversed. (00:15:19)
Factual error: Even if he was falling hard, Mandible still would've survived hitting the overturned root, as ants do not have much body mass.
Factual error: The plot revolves on finding a matching organ compatible with Nora. Practically the only issue presented about it is the blood type compatibility, so let's go by that logic. In a misconception happening in so many works of fiction, the fact that she is an AB - is listed as a terrible problem because of how rare it is. It is indeed the rarest blood type in most parts of the world, but it's also the universal receiver and compatible with every other group.
