Trivia: Technically this wouldn't count as a mistake since it requires going through frame-by-frame, but there's an amusing little flub in the pod-race. When Sebulba's craft crashes, go through frame-by-frame when his one engine hits the rock formation. The rock formation actually begins to explode a frame or two before the engine strikes it. It's hard to tell it's happening when viewing the movie at normal speed, but you can catch it going frame-by-frame. Just an amusing little slip-up in the rendering.

Revealing mistake: In a few of the wider crowd shots during the pod-race, you can make out some oddities. In particular, if you look closely, you'll see the same group people copy/pasted over and over in different places and different configurations in the audience to make the crowds seem bigger. (Slow motion or pausing helps, but is not necessary.) This is actually a relatively common special effects trick to make crowds seem bigger.
