The Writer’s Journey began as a memo.
Working at Disney during the 1980s, Christopher Vogler saw senior executives using memos effectively. He wrote one to summarise The Hero with a Thousand Faces, as he was sure Joseph Campbell’s book had inspired George Lucas’s Star Wars. He wrote a 7-page memo that became so popular he expanded it into a book. This became the ‘Bible’ for beginning scriptwriters. He called it a ‘practical guide’, since besides summarising Campbell’s ideas on narrative, he showed how they could be used to write film scripts.
Question: what else could start with just a memo?
