Here we go with yet another retcon question about Star Wars. While looking up info on another film franchise, I came across this intriguing internet tidbit:
As a bit of irony in the muddled Star Wars saga, Lucas actually had a traditional Mercury / Gemini type American astronaut in the original Cantina scene. Look for him to cross from right to left with his drink near the bar. He's in full flight gear and the American flag is easy to see on his left shoulder. This has often been described in the blooper blogs as "a galaxy not quite so far away."
However, I was not able to verify the truth of the statement. What evidence is there that proves or disproves there was a Gemini Earth Astronaut that appeared in the original Star Wars Cantina scene?
