Yoda meeting Chewbacca. Absolutely unnecessary. Chewbacca. Also absolutely unnecessary. And of course Han Solo was featured in the rough draft of the script and some concept art was done. To me, the idea that Lucas actually seriously considered this is a huge strike against his shrinking universe and it isn't forgiven even though he jettisoned the idea..

One idea that I would like seen looked at with a little more depth is R2 and 3PO. Although they were introduced in the wrong places and with the wrong people, I am torn whether they should be in the prequels or not. Lucas has stated rather early on that the story would be viewed from the eyes of the droids. I do like this idea, but I am not sure if the prequels can be about Ben and Anakin and the droids. I'm not sure how this all would work.
