Universal Myth

Joseph Campbell's influential The Hero With a Thousand Faces defines the "Universal Myth," a structure which underlies stories told all over the world since the beginning of recorded history. This page discusses how Campbell's blueprint for "The Hero's Journey" was used by George Lucas in making Star Wars (the page also discusses Campbell's influence on The Matrix). This interesting article and other influences and origins of Star Wars mythology can be found on this Star Wars Origins site. Another interesting site for the futuristic myths produced by science fiction is The New Mythology; there's lots of discussion and a ton of links (references include Star Wars, Dune, Asimov, Enders Game, and more!)
