Read "The Star Wars" last week. What a trip that thing is. It's a graphic novel that Darkhorse made. It's based on rough draft script that GL did for EP4. Has some really cool stuff in it but boy am I glad it never made it to the big screen.
Here's a few things that were interesting.
Luke is a General and an old man. This is probably the role of Obi-Wan in the films.
Anakin is the understudy to General Skywalker and he saves Leia from the "Giant Space Fortress".
Han Solo is a giant green alien.
Vader is a Moff, think Tarkin in EP4.
The Sith is a guy named Prince Valorum. He ends up helping Anakin in the rescue of Leia. The plan when the book ends is for the Jedi and Sith to team up and take down the Emperor.
There's a scene where Leia is running her mouth and Anakin straight up punches her in the face and knocks her out because he doesn't have time to hear it from her.
Anakin helps rescue some Wookies from slavers. The slavers are Fett, Dengar, Bosk, and 4-Lom. It takes place on Yavin.
Storm Troopers wield light sabers. Hell, Han Solo at one point uses one.
