I have to point out again just how unique and original STAR WARS was to audiences in 1977.
Imagine trying to create a world that would last for 50 years and more... so those original audiences were really seeing "the future" laid out before them.
Even the very first frame -- the star field -- up to 1977, most sci-fi had mostly empty black space with a few twinkles here and there. Even 2001 had mostly black space. But with Star Wars, the sky was full of stars -- and endless realm of worlds sparkling! Even just that simple thing was a marvel to see...
