um, george is not a very good writer. He had Williard Huyck and Gloria Katz help him on the first screenplay, and lawrence kasden pretty much wrote all of empire and jedi. He comes up with the story concept technical details in the script like camera moves etc., but he is a terrible writer, but he is a great visual storyteller avante garde filmaker. Carrie Fisher was the script doctor on the Phantom Menace, and Jonathan Hales who wrote several scripts for young indy helped with attack of the clones. Lucas reportedly wrote revenge all by himself, and when you watch the film you can see the results of this. If you read the Matthew Stover Novelization you really wish other than getting into the chracters heads, it would've been great if they filmed that. Although much darker than the film, it would've gotten An R rating and not made as much money, but would have been a better film. Just like Terry Brooks Novelization is better than the phantom menace film, and also attack of the clones by r.a. salvatore was better than the film. Lucas even had help with the opening scrawl of the first star wars, spielberg, depalma, scorcese helped him rewrite it so it was coherant. Even Coppola helped lucas with some of the first drafts of star wars, just like he did for thx 1138 and american graffiti.
