I had to do some more skimming as I couldn't quite take the constant talk about the original film's script revisions (don't worry, I'll come back to it when I can), but I noticed you pointed out the Rosie O'Donnell interview. I remember watching that! She thought Darth Maul was actually Mace Windu in disguise and then actually asked George if she was right. His reply was a simple "no." She also asked him if he ever watched Star Trek and he said something like "I caught a few episodes but I wasn't a Trekkie or anything." I think he was also asked how long until Episode II would be released and it was "3 years, although I wish it was 4."
I've skimmed over huge sections now, including the one about George and Marcia's divorce. I didn't see anything addressing the rumors that Marcia got %15 of sales of the OT and that maybe that's why George changed them into different movies, aka the Special Editions. On the other hand, I guess there wouldn't be much documentable evidence to treat that as anything more than it is, rumor.
Also, I didn't know that the official fan club actually shut down at one point. I know people always refer to the late 80's as the dark times but I didn't know it was that dark.
