I wonder what kind of negative Lucasfilm sent derann.
They only had star wars and Return of the jedi and never Empire strikes back.
Earlier prints run off were incredibly sharp but the last ones rolled out were not as good.
These were the same as the 35mm versions of the film, not sure if star wars was just star wars or it had the episode IV,
Jedi was identical to the 35mm engagements of 1983 and 1985, only the stereo dolby audio was folded into monaural. And it was super8mm scope.
Of course magnetic sound and not optical.
