That all we have is the non anamorphic 2006 gout home video release vs memories of its original theatrical exhibition in 35mm and 70mm showcase theaters.
i'm suprised the guy did not face legal action from lucas for screening a non special edition version for a few friends.
indeed he has done everything he could do to keep them out of the hands of private collectors including recalling all original theatrical prints and having them destroyed.
He could not get his hands on the library of Congress copies. Afi copies or bfi copies though. That and the fact that a few unnamed collectors possess original versions leaves some hope.
I think the original I.P.'s as well as the dailies and selected takes still exist on reels in lucas cold storage vault. as well as the dye transfer print of 1977 star wars.
We do know he cut up and altered the original physical negative to make the special edition. this seems to me actually a almost criminal outrage, that the original footage cut ended up in trim bins and destroyed is beyond words.
one of the reasons i have not gone and have boycotted the star wars celebrations is because they don't even show versions of the original films. We know lucas has prints in his vaults someplace, he would not have been crazy enough to have them destroyed as well.
