Narrative and Character in Thrillers

Every thriller film has 5 parts to the narrative that come in an order. These are:
Equilibrium --> disruption --> complication --> resolution --> new equilibrium

For example, in the movie Jaw's, these would be:
Equilibrium = everyone is happy on a beach, preparing for the 4th of july festival.
Disruption = A dead body is found which has been eaten by a shark.
Complication = do they close the beach? keep it open? is it a shark? are there more deaths to come? Another person dies.
Resolution = They decide to catch and kill the shark - so keep the beach open.
New equilibrium = shark is killed and shark hunter dies - everything goes back to normal, but relationships have changed so it is a NEW equilibrium.

Every film usually has 5 common characters too:

• The hero - the one on the quest and the one who saves the day
• The villain - the evil one who causes the disruption.
• The helper - The person who helps the hero on the quest ( the sidekick)
• The victim - The one at the mercy of the villain.
• The donor - Someone who has something special which will help the hero.  

An example of this is Harry Potter and the Prisoner of Azkaban:
The hero: Harry Potter
The villain: Voldemort
The helper(s): Hermione & Ron
The victim: Serious Black
The donor: Dumbledor
