Revealing mistake: In several scenes, it is obvious that the animal actor playing Bagheera is actually a black jaguar. For example, the jaguar is larger and heavier than the leopard/panther. The scene where Bagheera tackles a poacher, he is much too large and heavy to be a leopard/panther.
Revealing mistake: When Mowgli is on the burning wagon, as it's being pulled away from camp, you can tell that in certain shots it's really a stunt double and not Mowgli at all.
