Okay, so Kurtz and Lucas disagreed on this stuff. Lucas wanted everything listed in your post and Kurtz didn't. They fought and subsequently parted ways forever only to see Lucas overturn his initial ideas and wind up in agreement with Kurtz. Typical.

VT, okay I should have been more specific. I didn't mean that he had the script written, but he had it all planned out when he did ESB. You would have to in order to justify having a cliffhanger ending like the one in ESB. You have to know ahead of time where you will take it. Maybe not the dialogue involved, but the story was pretty well planned with some exceptions.
