I don't know. I still have a funny feeling that a fully restored OOT exists. Empire of Dreams and the opening crawl to the GOUT really drop a lot of hints at this. Of course, I could be mistaken and only those few shots were restored (just seems unlikely to me). But even if there is no real LFL restoration of the thing lying around, I find it hard to believe nobody else has taken it upon themselves to preserve this thing. Keep in mind, it is Star Wars we are talking about here. This was no poor quality B-movie, this thing has been a hit since its release. Very influencial. Many awards.
There are a lot of powerful people in Hollywood with the ability to make things happen, and with access to things and places our little community could never reach. Legally, George can sit on his movies and prevent an official release, and there is nothing anyone can do about it, if they did, it would probably cause hard feelings, and I don't think anyone really wants any drama between them and GL. But none of this means restorations and preservations cannot be done behind the scenes and hung onto for a rainy day. This is the 21st century man! I have a hard time believing when live in an age where things like this can still be lost forever. Too many people with too much technology floating around. I mean, how crazy is it that an obscure TV broadcast of the Star Wars Holiday Special still exists in pretty decent quality thanks to people owning VCRs in an age where the things were nearly unheard of?
I have absolutely no doubt one day Star Wars will be readily availble with its original visuals in as perfect quality as humanly imaginable. I just don't see this happening in the near future.
