Other mistake: (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.
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.
