It’s sometimes hard to pin Star Wars down due to the many different genres Lucas took his inspiration from. From the westerns of John Ford to the Japanese Films of Akira Kurosawa. There’s a couple of scenes in the original Star Wars that are lifted almost verbatim trom Kurosawa’s films “Sanjuro and “The Hidden Fortress”.

Honestly I think that is what most art is: Inspired by other artists that preceded it.
I did a “work of art” piece of pottery in 8th grade that got an A+ and they displayed it in the school trophy case. I told the teacher that I felt guilty because I based it on some other piece of art. He said, that is where ALL art comes from.
I think Star Wars did a really good job of realizing its inspiration from other artists. At least the first one did. And The Empire Strikes Back was the only one for grown ups.
