When the 'special' editions were released on dvd they also included the original untouched versions. Very hard to come by now as Lucas and now Disney deny they ever existed.
I've got this too. Might be one of the few media items I've retained through dozens of moves, because I know it would be impossible to replace! I think George literally claimed the OT no longer existed (something about disappeared masters) at one time, but I'm almost positive that was before these special editions were released after people kept badgering him about it.
Ah, yes. Now I do some searching I see those - and very pricey they are too!
It would be nice if the original cinema cut was re-released (preferably a cleaned up version). Presumably this is possible? Presumably even the "special" editions can be used - with the added bits removed? And now that Disney have taken control, they don't need to contend with Lucas's whims?
There was a lot of speculation about that when Lucas sold to Disney and as I recall, Disney made some vague statement about the movies being what George said they were that poured cold water on the idea. It had me wondering if one of the terms of the sale was Disney couldn't scrap Lucas's edits and had to retain them in all future versions.
That said, if Disney is willing to stiff Alan Dean Foster on his novelization royalties, I have to believe they have thought about doing it anyway. A 4k ultra remastered version of the OT would undoubtedly sell big to the generations that have been lukewarm on the latest trilogy. Maybe they're waiting until they feel they need a reset.
