Deliberate "mistake": At the elephant graveyard, little Simba claws Shenzi in the face. When Mufasa saves Simba from the hyenas, the cuts are gone, a few seconds later. [This was done intentionally, I'm sure, for two reasons. The first being, Disney doesn't let fresh scars linger on the screen too long. Secondly, during that same scene when Mufasa rescues Simba & Nala, he claws Banzai in the rear. To stress the point later in the movie, that severe scar is shown too, but only briefly, it too disappears because of reason 1. Still a "mistake", but there's why.]

Continuity: When Timon rides Pumbaa through the vultures that are crowding around Simba, they run right over where Simba should be, but he's not there. 2 seconds later, after all the vultures are gone, Simba is back.

Factual error: When Mufasa is showing Simba the kingdom from Pride Rock they are facing the sun, yet Pride Rock's shadow is visible below them. Also in the same position, you see that they have shadows behind them. Then a few seconds later when Simba sees the shadow area the shadows are in front of them while you can see part of the sun to their left side. They would be facing south when the sun is east. How are their shadows in front of them?

Continuity: Nala's eyes change from blue to green quite often during the movie.

Continuity: When Simba and Nala fall through the dead elephant, there are some small rocks near them. But after the hyenas say, "Here kitty kitty kitty," Simba makes a small roar and the rocks are gone.

Continuity: When Rafiki is showing Simba where his father is, Simba is following Rafiki through the trees and they arrive at a river/lake. Rafiki says 'shh' and pulls the grass apart. The thing is, he pulls away one side of the grass and the other side parts as well without him moving it.

Continuity: During the stampede in the gorge, when Simba jumps up on the dead branch, he leaves very distinct claw scratches. Then in the following scenes they're gone, although other marks and details on the branch remain.

Deliberate "mistake": Rafiki is supposed to be a mandrill, but mandrill's do not have tails. In the recently released Extended-Version DVD, there is a commentary by an animator who specifically admits that he knew that mandrills don't have tails (at least not like the length that Rafiki sports throughout the movie), but he put one on him anyway to make him more monkey-like.

Factual error: In the scene when Simba and Nala meet as adults, they rub heads and begin to purr. Lions can purr, but they only purr when they exhale, and Simba and Nala were purring when inhaling and exhaling, like house cats.

Continuity: When Simba walks away from the jungle and Timon says, "He looks blue," Simba is at a fair distance from the shadow of the tree. But a few shots later, Pumbaa comes to Simba and asks, "Kid, what's eating ya?" but Simba is now closer to she shadow of the tree.

Continuity: At the beginning when Rafiki puts the paint on the picture of Simba (on the tree trunk) the paint goes on a different color than it is. The film makers admit this mistake on the commentary.

Continuity: When Simba and Nala are in the elephant graveyard, Simba goes to see if "it's brains are still in there" and he's past the base of the trunk. But when Zazu pops up in front of him, he hasn't passed the base of the tusk yet.

Continuity: When Timon and Pumbaa are inspecting unconscious Simba, Simba's paw is lying over his eye. In the next shot, right before Timon lifts the paw up, it has moved to below his eye.

Deliberate "mistake": As the rain extinguishes the fire at Pride Rock, Simba passes Zazu, who bows to him and you see him mouthing words to Simba. The words "your majesty" were cut out of the film, in order to have a poignant silent moment.

Continuity: When Rafiki dips his fingers in the orange paint to put a mane on Simba's picture, the paint is not on his thumb. He raises his hand up close to the picture, then, a split second later in the next shot, the paint is on his thumb with which he starts to paint the mane. He did not have time to dip his hand in again.

Continuity: After Pumbaa kisses Simba's feet, Timon says, "Don't he's not the king," he puts his hands on the middle of Pumbaa's snout. But in the very next shot, Timon's hands are now at the top of Pumbaa's snout.

Continuity: When Simba and the animals begin to tower up on each other towards the end of the song "I Just Can't Wait To Be King", a shot shows that the red elephants are close to the bottom of the tower. The camera begins to scan upwards and the antelope are towards the top where Simba and Nala show up. When the animals all fall and quick shots show how jumbled they get, a red elephant somehow ends up falling on top of an antelope's antlers which shouldn't be possible.

Continuity: When Simba finally sees his father's ghost in the clouds, he first stands in front of the water. As Mufasa begins to fade away, Simba suddenly runs forward, exactly where the water should be, yet it's not there.

Other: When Scar is circling Ed the hyena during or just before singing "Be Prepared," from the front Ed's tongue is hanging out. But from the side/back view, where the tongue should still be visible, it's gone.

Continuity: In the scene where young Simba and Nala are singing, "I Just Can't Wait To Be King," and right before making faces at Zazu, Nala steps into the water with both front feet, but in the next shot, all her feet are firmly on dry ground.
