Finally, its coming... Been waiting for it quite some time. Star Wars III : Revenge of the Sith I have been quite fascinated by the Star Wars Saga. Although it's the typical "A New Hope" story. But, the complex, cohesive universe setting with some beautiful characters make this quite a beautiful movie series [save for Attack of the Clones]. I even managed to read the script/dialogues version of "The Phantom Menace". I should say that Lucas was indeed going somewhere with that. I am waiting for this movie eagerly where in Darth Vader finally is made!
Searched around and found the plot of "Revenge of the Sith"! [Warning: This will spoil the movie per se, but I wanted to read it coz I can't wait till its released here! =D!
Bah humbug, I am too interested in Star wars now. A simple search in Google brought home these babies. They are the scripts in detail of the movies, save for the ones after Episode VI. They are plots for the movies/book.
Here are the links for the scripts [final version] of the movies. Go to the parent site for the corresponding drafts in case you are interested
Episode III: Revenge of the Sith
Episode VII: The Fallen Hero [supposed to be penned by Lucas himself]
On a related topic I found a document detailing the history of the Jedi and the Sith. Pretty interesting read. History of the Jedi and Sith.
