The Emperor's New Groove came out 20 years ago, during a time when Disney's animation department was going through an identity crisis. The plot is simple: David Spade is a bratty emperor. Eartha Kitt and Patrick Warburton turn him into a llama. And John Goodman is the peasant who helps make things right. It was originally gonna be an epic musical, but then it became a comedy, a box-office disappointment, and now, we would argue, a beloved classic.
