Based on Joseph Campbell's theories Christopher Vogler developed a structure model for writers which I find very useful. Chris read The Hero With A Thousand Faces when he attended film school at the University of Southern California. Studying Campbell's theory he discovered a secret code of storytelling. This was in the mid-70's when coincidentally George Lucas's first Star Wars film came out. Chris could see that Lucas had been influenced by Campbell and that his ideas had vast application to moviemaking. I apply Vogler's mythic structure occasionally to my story architecture.
