the blooper reels are pretty funny! No wonder everyone on set back in the day thought the first movie was going to suck! David Prowse had he busting a gut he was so funny, between his accent and dialogue I am not sure which was funnier.
On the topic at hand I don't think Disney can do anything with the OT until 20th Century Fox's rights run out. Hopefully Adywan will be done with the OT edits before then.
