The model was originally devised by the scholar Joseph Campbell, who studied myths from around the world and discovered a common underlying "scaffolding" on which they all seem to be built. Later, the writer Christopher Voegler popularized the hero's journey as a tool for screenwriters. Using Campbell's work as well as psychologist Carl Jung's definition of various archetypes, Voegler modified and popularized the hero's journey model, making it more accessible to a non-scholarly audience. Others have modified the stages in the hero's journey as well, but they all adhere to a fairly simple structure. At its simplest, the stages can be defined as departure, initiation, and return. Each of these can be further broken down into sub-stages.
The following is Voegler's version:
1. THE ORDINARY WORLD. The hero, uneasy, uncomfortable or unaware, is introduced sympathetically so the audience can identify with the situation or dilemma. The hero is shown against a background of environment, heredity, and personal history. Some kind of polarity in the hero’s life is pulling in different directions and causing stress.
2. THE CALL TO ADVENTURE. Something shakes up the situation, either from external pressures or from something rising up from deep within, so the hero must face the beginnings of change.
3. REFUSAL OF THE CALL. The hero feels the fear of the unknown and tries to turn away from the adventure, however briefly. Alternately, another character may express the uncertainty and danger ahead.
4. MEETING WITH THE MENTOR. The hero comes across a seasoned traveler of the worlds who gives him or her training, equipment, or advice that will help on the journey. Or the hero reaches within to a source of courage and wisdom.
5. CROSSING THE THRESHOLD. At the end of Act One, the hero commits to leaving the Ordinary World and entering a new region or condition with unfamiliar rules and values.
6. TESTS, ALLIES AND ENEMIES. The hero is tested and sorts out allegiances in the Special World.
7. APPROACH. The hero and newfound allies prepare for the major challenge in the Special world.
8. THE ORDEAL. Near the middle of the story, the hero enters a central space in the Special World and confronts death or faces his or her greatest fear. Out of the moment of death comes a new life.
9. THE REWARD. The hero takes possession of the treasure won by facing death. There may be celebration, but there is also danger of losing the treasure again.
10. THE ROAD BACK. About three-fourths of the way through the story, the hero is driven to complete the adventure, leaving the Special World to be sure the treasure is brought home. Often a chase scene signals the urgency and danger of the mission.
11. THE RESURRECTION. At the climax, the hero is severely tested once more on the threshold of home. He or she is purified by a last sacrifice, another moment of death and rebirth, but on a higher and more complete level. By the hero’s action, the polarities that were in conflict at the beginning are finally resolved.
