Lucas got a lot of feedback from people over several years as he revised his initial concept. https://starwars.fandom.com/wiki/The_Star_Wars_rough_draft https://starwars.fandom.com/wiki/The_Star_Wars_rough_draft The first version was not very Campbellian and did not have "Use the force." He also didn't come up with the "I am your father" story arc until after finishing the first movie.
