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.
Factual error: When Mufasa is initially showing Simba the pridelands they are facing the rising sun - in other words east. Simba asks about "that shadowy place" which is off to the right, and is told he must never go there. When Simba is later telling Scar about seeing the whole kingdom, Scar says "He didn't tell you what's beyond that rise on the northern border." It's the same place that Mufasa was talking about, as Simba says he's not allowed to go there, but if it was to the right as they faced east it would have been the southern border of the pridelands.

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
Deliberate mistake: When Rafiki comes to the pride rock for Simba's anointing, one minute he is walking through the assembled animals, the next he climbs onto the top of the rock from the front. Physically, even for an ape, it's impossible. It's a deliberate mistake, obviously his arrival would have been much less impressive if he had had to climb the mountain from the side in a slow but realistic way. (00:02:35)
Revealing mistake: One shot before Simba and Nala exchange lines on either side of Zazu during "I Just Can't Wait to Be King", Simba leaps to the opposite edge of a small pool of water. But notice how Zazu has been animated with a completely translucent reflection and, here, we can see the image of Simba right through him, which shouldn't happen. (00:15:35)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
Continuity mistake: The number of feathers in Zazu's tail repeatedly changes from three to four throughout the film.
Continuity mistake: When the bird bows down at the start, the lion is smiling, in the next shot, he is no longer, and he didn't have time to wipe the smile off his face. (00:01:45)
