Too many plot wholes. in the original stoy material as evidenced by the john l. flynn fanfic fall of the republic, Obi wan was to retrieve anakin's lightsaber that he later gave to luke. Boba Fett was supposed to appear and was in earlier drafts see making of revenge of the sith book. Han Solo was also going to be in it and the birth of the rebel alliance. Who knows boba will probalbly appear in the 2006 t.v. show since lucas would consider him a supporting role, and not one of the original characters who play central roles in either trilogy. Lucas did'nt mention the mythic mandalorian material, and the correlians were the first to sign with the rebel alliance. Han Not being in it seems to make sense though, seeing that he did'nt meet chewie until he was in the imperial navy as a cadet out of the academy, and was drummed out of the service for befriending chewie. i thought the wookie planet originally would look like endor, since that is where the concept came from for rotj, and lucas changed the wookie army into ewoks.
