The Cameo: Warwick Davis (who played the main Ewok in Return Of The Jedi) had a couple of minor (but visible) background roles.
Creator Backlash bordering on Old Shame: Jake Lloyd isn't fond of his role in the movie, thanks to having been mocked about it since childhood. He's since destroyed all his Star Wars memorabilia and won't watch the films again.
Deleted Scene: This movie, like the others, has its fair share of deleted scenes. One of the more notable ones is where Qui-Gon and Anakin start to depart from Tatooine. One of Maul's sith droids attempts to tail them, only for Qui-Gon to suddenly slice it down, and then explaining they need to hurry back to the ship. This scene explained why immediately in the next scene, they were running back to the ship when the previous scene had them walking calmly from the market.
Another notable deleted scene, taking place after the podrace, involves Anakin beating the crap out of one of the other kids because he accused Anakin of cheating. Would have foreshadowed Anakin's prone to anger. Anakin's victim... a young Greedo.
The Japanese-dubbed version is an interesting case: Unlike the sequels, all the movies had the same voice actors, regardless the media and networks (and avoiding The Other Darrin trope that the original trilogy suffered in Japan for years). In fact, the only voice actors switched between movies was Palpatine and Jar Jar Binks's VAs, who died between Attack of the Clones, Revenge of the Sith and the animated series.

Recycled Script: The heroes visiting an underwater city to parlay with its ruler was originally a big plot point in Lucas' first draft for the original film, The Adventures of Starkiller: The Star Wars.
Star-Making Role: Both Ewan McGregor and Natalie Portman were well respected actors but were in either small roles or independent films. This movie made them big names. Ray Park also fits in, as his presence in the final battle was one of the most memorable parts of the movie.
On the other hand, it was a Star Derailing Role for Jake Lloyd. He was never a star, but he had a respectable career as a child actor before this film. He did one movie after it and then quit acting.
