Audio problem: (May only apply to the original VHS release.) When Scar has Zazu locked up in a cage, Zazu mentions Mufasa's name and Scar yells at him, "What did you say?" Right before Scar's actual line, whilst Zazu is talking, you hear Scar's "What did you say?" line very faintly in the background, even though Zazu has not even mentioned Mufasa yet.
Continuity mistake: The whites of Simba's eyes change frequently through the movie, from yellow to white. They're yellow up until the scene where Pumbaa, Timon, and Simba are stargazing; after that they change back and forth frequently. During the Mufasa-in-the-sky scene, when Simba asks, "How can I go back? I'm not who I used to be," they change from yellow to white and back within three frames.
Continuity mistake: Nala's eyes change from blue to green quite often during the movie.
Suggested correction: Her eyes were green the whole time. It's just lighting making it look like they changed color.
The correction assumes these lions are filmed, but they are drawn. So if the eyes are blue, they coloured it blue and if it's green they coloured it green, on purpose.
They are colored to emulate different lighting conditions. Note that the fur is also different colors in the different shots.
A darker shade of the same color isn't the same as a whole other color.
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 mistake: 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 mistake: 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. In the shot facing him and Simba, Rafiki is only holding the grass on the left back, but the grass on the right is bent back the exact same way, without anyone holding it back.
Continuity mistake: 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 the shadow of the tree.
Continuity mistake: 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.
Continuity mistake: 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.
Audio problem: When Mufasa is clinging onto the rock after rescuing Simba and Scar is above him he says 'Scar brother help me'. If you listen very carefully he says the word 'brother' twice but his mouth only moves the second time he says it.
Continuity mistake: 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 mistake: 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 mistake: 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.
Continuity mistake: 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.
Revealing mistake: When Nala tells Simba that she is taking her bath, Sarabi (Simba's mother) tells him "And it's time for yours," and picks him up in her mouth. Her head was animated but not the rest of her body (which remains in a sitting position) so her neck appears to stretch a few feet to reach Simba.
Continuity mistake: In the recent DVD release of the film that includes the new animated segment "The Morning Report", Simba is not drawn with whiskers. His nose also changes colour from the previous shot where he is walking and talking with Mufasa.
Continuity mistake: When Scar pushes Shenzi and Banzai into the geysers, they go flying across the cave. But when Scar is tiptoeing up the ridge, Shenzi is right next to him. The when all 3 are in the bone pile, she's there as well (with the long skull in the middle).
Other mistake: On the old Blu-ray cover of The Lion King, there are several mistakes. In the old version, Nala's face was different, as she had brown eyes instead of blue ones and had whiskers. Her head structure was also different and her eyebrows were larger. Rafiki's face is also different as well, his eyes are wide apart from each other and part of his nose is miscolored. While Simba's face is given a few addition in the new Blu-ray cover, Pumbaa had white eyes and Timon's head isn't facing to the front and didn't have dark eyelids. However, all of these mistakes were changed for the new Blu-ray cover.
Audio problem: In the scene where Sarabi gives Simba and Nala permission to go to the waterhole, Simba yells "Yeah!" and you can distinctly hear that Nala says "all right!" But it's animated so both Cubs appear to be exclaiming "Yeah!"
Continuity mistake: During the opening sequence, a group of elephants are marching towards the camera, along with a flock of blue birds. Once all of the birds have run offscreen, another suddenly runs out from behind the lead elephant's foot, even though we saw that there was no bird there a few seconds before.
