Although in the Autograph Hall you do have a good opportunity for speaking w/ them (Some do even come out for drinks socially afterwords)
It's funny, Kurtz seems 2 b so removed from Lucas now, did they have a falling out? (burned themselves out from one another I guess?)
I recall there was an auction (a while back) of Kurtz letting go of some of his private 'SW' collection (posters Etc.) don't recall anything else though
Here's hoping for those guests of interest 2 b making an appearance at one of these functions - sabers crossed!
