Lets start with the cast shall we, by changing the following:
Keaunu Reeves playing Qui gon Jinn
Ashton Kutcher playing Obi-wan Kenobi
Chris Tucker/Any of the Wayans brothers play Mace Windu
Alicia Silverstone plays Padme
As for the movie:
-Almost everything is CGI. Cartoonish, cheesy CGI. Think Final Fantasy: Spirits Within levels.
-Jar-Jar gets even more screentime. Also, all the gungans are like Jar Jar.
-The racial stereotype races like the Gungans or trade federation are even more rascist. Think of how well haveing the trade federationits have glasses, slanted eyes, buck teeth, and speak 'Engrish' would go over, or have the Gungans speak slave-jive.
-John Willaims does not do the score.
-Anakin gets more screen time. There is also a scene where he and Padme kiss. Tongue or no tongue, I'm not sure.
-The first ten minutes are literally trade negotiations.
-The final fight between Obiwan, Quigon and Darth Maul is turned into a long, drawn out negotiation over Jedi/Sith Religious Triestes.
-Darth Maul now talks, and he sounds like Crazy Frog. For that matter, he now looks like a five foot tall Pommeranian.
-The closest thing to a fight scene in the film is the Pod Race.
If we even get an Episode II if all this is done, I'll take it as proof of the non-existantce of God.
