The Theories of Todorov and Propp.

Todorov's theory of the narrative is a simplistic model that can be applied to most if not all films. The basis of the theory is similar to a cycle starting with a pre-exising equlibrium and culminating in a new equlibrium being established. The cycle goes like this:
- Equlibrium
- Disruption
- Recognition of disruption
- Resolution of disruption
- New equilibrium formed.

The diagram below shows the stages of the cycle.

Propps character theory is similiar to Todorov's narrative theory in the way that they are both a simplistic model that can be applied to most films. The difference with Propps theory is that it revolves around the characters, not the narrative. Propp theorised that there are several character arch-types that are present in most films, they are:
- The Hero, a character that is actively seeking something.
- The Villain, a character that tries to stop and disrupt the heroes actions.
- The Donor, a character that gives something vital to the hero (sometimes crucial information, other times a crucial object)
- The Dispatcher, the character that sends the hero on his quest.
- The False Hero, the character that falsely assumes the role of the hero.
- The Helper, the character that gives help and support to the hero.
- The Princess/Heroine, the reward for the hero but also a character that needs to be protected from the villain.
