I've seen it in 1983 in the best - giant - screen of Paris at that time (the Rex) wich had even stars shining in the dark on the ceiling + a damn great sound, and I had a good place facing the screen on the balcony (or circle).
I didn't retain the negative side of the film. I must have been somehow temporarilly "fooled", like a lot of people.
Anyway, I wanted to become a Jedi (not like my father before me) what is the essential.
