The 77 version of Star Wars is by far the movie Lucas has been the most outwardly unhappy with. Success and widespread appreciation can't make up for a blob under a landspeeder and a lack of cartoon dinosaurs.
I wonder what it takes for someone to check on the condition of the Library of Congress print. Is it accessible in any way or is all that just intended as a time capsule for long after we're all dead and the talking apes want to see what our world was like?
