Campbell: Hero's Journey/Monomyth

Joseph J. Campbell 

(b. 1904 - d. 1987)

Joseph Campbell was an American writer, professor, and folklorist. 

What is the Hero's Journey/Monomyth?: 

The term Monomyth was first seen in his 1949 book "The Hero with a Thousand Faces", where Campbell stated that the journey of the archetypal (Propp) hero spanned across mythology, hence why it is called the Monomyth. He stated that this is the ultimate archetype in the narrative, but the phrase "hero's journey" is more commonly used to describe the protagonists change within a narrative. 

From the book "The Hero with a Thousand Faces", he summarises it as: 

"A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from his mysterious adventure with the power to bestow boons on his fellow man."

Campbell states there are 17 stages of the Monomyth, but certain narratives chose to focus on fewer stages, or in different orders. However, they are separated into three stages: departure, initiation, and return. 

Possible influence for my film: 

The hero's journey of the final girl or the teenagers in discovering and killing the killer.
