Trivia: Disney wanted people to despise Scar, the film's villain, so, during Scar's big song 'Be prepared', they made references to Adolf Hitler. When Scar's army begins to march, they are goose-stepping like Nazi soldiers and have their snouts raised like a Nazi salute (their snouts appear longer here than in any other part of the movie, and pointed to their right). Scar is on a large ledge, which resembles a balcony, much like that used by Hitler - on the side, the rock has a pattern resembling a giant Swastika. And finally, on the ground where the army marches, lines appear. These lines were on the streets of Germany, where the Nazis paraded.
