Fairy tales and myths are like the dreams of an entire culture. The same character types seem to occur and remain amazingly constant throughout all times and cultures. An understanding of these forces is one of the most powerful tools a modern storyteller can learn.
The archetypes Jung identified as occurring most frequently were the Hero, the Mentor (wise old man or woman), Threshold Guardian, Herald, Shapeshifter, Shadow and Trickster. To learn more specifics about Jung and his archetypes, please visit http://webspace.ship.edu/cgboer/jung.html
Scholar Joseph Campbell took Jung’s principles and adapted them to teach screenwriting. In essence he simplified a pattern or outline for writer’s to follow, making it easier for many authors to become successful in his publication of The Hero’s Journey.

I used Christopher Vogler’s (a student of Campbell) book The Writer’s Journey when I was teaching. I used his material instead of Campbell’s because I actually had the pleasure of meeting and learning from him and because I felt he did an excellent job of updating Jung’s original principles. You can find an abridged version: http://www.thewritersjourney.com/hero's_journey.htm
Both Campbell and Vogler have only updated and helped to define Jung’s original ideas of archetypes and the journey of a story. Reading about all three can give you a better understanding of human nature and what we all want from a good book or movie. Good luck with your own writing journey!
