The Emperor's New Groove (2000)

Continuity mistake: When Kronk is disposing of the llama body, he runs down a very tall staircase. At the bottom, he runs into two peasants and leans up against the wall. The peasants pass him, walking toward the left side of the screen. Immediately after they disappear from the screen, the "camera" zooms out so you can see the entire palace. Now, the only place the peasants could have gone was up the staircase Kronk had just come down from, unless they wanted to fall off a cliff. If you look on the stairs, though, no one is there. The peasants couldn't have made it all the way up the extremely tall and steep staircase within seconds, so they just mysteriously disappeared.

Yzma: That's it, Kronk! Break the door down!
Kronk: Break it down? Are you kidding me? This is hand-carved mahogany!

Trivia: This the first Disney animated feature to show a pregnant woman.
