Or that chewie and han were raised as brothers on the wookiee home world. lets be thanfull these concepts did not make it into the movie proper although they were in earlier scripts as evidenced by the making of star wars revenge of the sith book by rinzler.
also Lucas ex Marcia was his best collaborator and someone who kept him grounded and added a warmth and human element to his films that was not there without her. She was literally the most talented editor hollywood ever had and the fact that she left the business is a great loss.
Even spielberg has said that marcia was a better editor than even verna fields.
she was literally in a creative aspect george's other half so he is now half what he was when he was with her.
her importance to the early days of lucasfilm is covered in depth in pollock dales biography of lucas skywalking and is notisably absent from lucas sanctioned apologist pieces.
It also covers the fights and competition lucas had with coppola which lucas denies really happened. Francis is like the older brother George never had, even he says so, so there were bound to be dissagreements which made both of there films better.
one of the thing people hardly ever talk about or consider is the imcompability in tone of both trilogys becuase an older george is different than his younger self. when one ages decades they are not the same person it is the same with authors of novels as with filmakers.
