Kurtz was also asked to produce Revenge Of The Jedi - which he turned down for the reasons we all know…
That seems extremely unlikely. After falling out with Lucas, it would be ludicrous to think that Lucas would ask him to do anything for him after that.
Like Lucas asking him to stay around until the film was finished? As stated below in your reply to Wook? 😉
Or Kurtz being mentioned as being ‘a Production Consultant’ in an official Lucasfilm press release for Revenge Of The Jedi, in 1981… seemingly not so ‘ludicrous’ as some may think, afterall…

^ “Gary Kurtz was asked to produce Revenge of the Jedi (Return of The Jedi) and turned it down as he felt the script was too limited and that most of what was in the script had already been seen in the first two films (i.e. another Death Star and the sand planet). He had worked on the Star Wars films for many years now and wanted to continue with changing the direction of filmmaking.” - by Jason Joiner, of the Joiner/Kurtz Archive

^ '“It wasn’t acrimonious”, Kurtz said his departure. "It was just that [Lucas] felt he would probably be more comfortable with someone else handling the production of Jedi, and I felt I would prefer a different kind of challenge, that wasn’t kind of repeating something I had already done."’

^ Bantha Tracks: Issue 11 (official Star Wars Newsletter), dated February 1981, re Revenge Of The Jedi and an official Lucasfilm press release:-
“Gary Kurtz, who produced ‘Star Wars’ and ‘Empire Strikes Back’ will serve as a Production Consultant on ‘Jedi’, while he prepares two of his own projects.”
I thought George’s beef was with the DGA and that didn’t happen until Empire was finished?
Yes, but that is a different matter. Regarding PGA, that was just my speculation why they officially kept him around, when he was already effectively replaced. It is safe to assume that Lucas did not want to get in trouble with PGA over something like that.
