Did George Lucas come up with every idea in Star Wars?
Nope. Lucas wrote the stories and oversaw every aspect of production, but of course a lot of credit goes to the people he worked with. Particularly significant contributors include Ralph McQuarie, whose paintings created the “look” of the original trilogy, Lawrence Kasdan, who cowrote The Empire Strikes Back and Return of the Jedi, and John Williams, who composed all the music.
