Continuity mistake: When the three hyenas are chasing little Simba, Banzai, (a hyena) flies into a thorn patch. When he comes out, he is covered in thorns. Then he walks over to the edge with Shenzi, and all of the thorns are gone (the ones he didn't pull out). (00:40:20)
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.
Continuity mistake: When Simba is running from the trio of hyenas that Scar sent out to kill him, he's forced to stop in his tracks at the foot of a steep cliff. Down at the bottom are thorn patches, and the sun casts a shadow on their right sides. Obviously this implies that it's setting on the left hand side of the cliff - and it's visible on that horizon moments later as he tumbles down the face. Once Simba clears the bushes and heads off into exile, Banzai shouts "If you ever come back, we'll kill you!" At this point notice how Simba is chasing the sunset, but now it's in an entirely different location - opposite the cliff face. (00:38:50)ryguy_1983
Continuity mistake: When Mufasa is showing Simba how to pounce, Zazu is facing backwards when Simba pounces on him, but when Simba has Zazu pinned to the ground, his paws are on Zazu's front. Simba would hardly have released Zazu to let him turn round. In the recent release of an Extended-Version DVD, Zazu sings a song called "Morning Report" which was written for the stage show and added to the extended version DVD. Zazu's change in position comes from the material that was cut. Still a mistake, but there's the explanation. (00:11:05)rabid anarchist
Continuity mistake: When Simba is lying on a rock awaiting Scar's surprise at the base of the gorge, he tries to intimidate a nearby chameleon with his (weak) roar. The shot changes and Simba finally scares it away, but notice how the rock has disappeared. Now all we can see is a blurry background of the gorge's edge. (00:32:10)ryguy_1983
Continuity mistake: When the three hyenas are chasing Simba and Nala in the elephant graveyard, one of them is standing on top of a bone, then next second the bone is gone.
Continuity mistake: At one point during "Hakuna Matata" Timon raises Pumbaa high into the air with a vine. As Simba watches from below, the sun casts a long shadow behind him. In the following shot, however, a shadow appears beneath him - as if the sun were located directly above. (00:45:30)ryguy_1983
Continuity mistake: After reuniting with Simba, one of Nala's paws changes its place on the ground between shots. When Simba denies being the king, he begins to walk off screen to the left. Here, Nala stands several feet away from Timon. But by the next shot one of her paws is suddenly inches behind Timon instead. (00:56:40)ryguy_1983
