I think its very interesting it says that George Lucas was inspired by Stories like Dune.Flash Gordon,Akira Kurosawa Movies like The Hidden Fortress,The Foundation Books by Isaac Asimov,The Skylark of Space by Edward Elmer Smith,The Force concept was inspired from New Gods The Source by Jack Kirby,The Lensman Books by Edward Elmer Smith The Cosmic All,Tales of Power by Carlos Castaneda The Force of Others,Galactic Patrol,Darth Vader design was inspired from Doctor Doom by Marvel the Villain of The Fighting Devil Dogs,Darkseid from New Gods

Originally Lucas didnt want to do his own Story but a Remake of Flash Gordon highly recommended Book
