Oh boo hoo! "dashed dreams" as opposed to the ones that were destroyed by Ford when they left initially... not to mention lives ,family and city destroyed in that process ... so bad that Detroit filed bankruptcy

influence came from professor Joseph Campbell .. whom taught mythology and theology at Sarah Lawrence College. of course parts of Japanese culture has been borrowed as well myths of other culture but it came via professor Campbell

George Lucas was the first Hollywood filmmaker to credit Campbell's influence. Lucas stated, following the release of the first Star Wars film in 1977, that its story was shaped, in part, by ideas described in The Hero with a Thousand Faces and other works of Campbell's. look it up... there is also a video of a interview with Lucas on this fact.
