And what was also left out of the debate so far is that the ultimate release of Star Wars in '77, for which the crew must have been aiming, was not 35mm prints but 70mm prints.
What's to debate? It was definitely the rolls royce with its fantastic magnetic six-track audio and superior projection quality. But Star Wars was a 35mm film, the 70mm prints were blow-ups. The way I understand it - a much coarser image compared to the olden days true 65mm/70mm films. But a brighter, sharper and more steady image compared to regular 35mm showings.
I managed to see ESB in 70mm in '80 without even knowing it until many years after. Damn, how much I want to travel back in time.
