Why was Star Wars made?

Here's what I got, after doing some looking around...

The archetypal plot was influenced by a varied anthology of sources and eclectic references:
  • legendary Buck Rogers and Flash Gordon comic-book heroes and films [Lucas had originally wanted to remake the 1930's Flash Gordon movie serials, but the rights to the comic book character were snapped up first by Dino Di Laurentiis]; the works of cartoonist Alex Raymond included Flash Gordon and Jungle Jim; Lucas cited the classic movie serial Flash Gordon Conquers the Universe (1940) as the direct inspiration for his own space opera
  • previous science fiction films (such as Forbidden Planet (1956) and Stanley Kubrick's 2001: A Space Odyssey (1968))
  • the saloon setting of westerns (as a model for the inter-galactic watering hole)
  • the James Bond films
  • Joseph Campbell's book The Hero with a Thousand Faces
  • Carlos Castaneda's Tales of Power
  • medieval knights (King Arthur and Camelot) [Camelot's story also told of a young Prince, who with the help of a sorcerer/Merlin, a Sword and 'the Force' saves a Queen and defeats the Black Knight with the help of his Roundtable aides.]
  • sorcerers' tales and stories about magic (Tolkien's Lord of the Rings and Carlos Castaneda tales)
  • warrior legends, myths, fairy tales
  • Western good-guy vs. bad-guy stories
  • elements of other classic films or tales (The Wizard of Oz (1939), John Ford's The Searchers (1956s), TV's Star Trek, Fritz Lang's Metropolis (1927, Germ.),Riefenstahl's Triumph of the Will (1935, Germ.), and Kurosawa's The Hidden Fortress (1958, Jp.) and Yojimbo (1961))
  • Errol Flynn swashbucklers
  • dogfight-filled WWII war films, such as 633 Squadron (1964)
  • similar to the Greek tradition of beginning an epic in the middle ("in medias res"), this film (the first in a trilogy) was the fourth film in the entire series
