Todorov Narrative and film trailers

Tzvetan Todorov came up with the idea of equilibrium and disequilibrium in the narrative of a story. Here are the 5 stages that he narrative goes through, according to him;

1. Equilibrium - everything is functioning normally in the fictional setting.
2. Disequilibrium - there is a disruption in the environment, which turns the world upside down.
3. Recognition - the characters recognise the disruption.
4. Repair - they attempt to solve the issues that the disruption has caused.
5. New equilibrium - the society either goes back to normal, or a new one is formed. Either way, there is a new environment, in which society functions normally again.

An example of this structure is the trailer for Independence Day.

This is a movie about the end of the world. It is set in our reality, which we are already familiar with. This is the 'equilibrium' stage of the theory.
The trailer then shows news reports and footage of destruction; which shows the disruption of live as we know it. The main characters recognise this, as the world descends into chaos.
They try to 'repair' the circumstances by escaping and fighting for survival. Government officials also attempt to fight the enemy.
A new equilibrium is not shown at the end of the trailer, because this would ruin how the movie ends. But it will either end with the characters being annihilated, or defeating the enemy, or compromising with the enemy and starting a new world.
I think this a suitable narrative structure for disaster films. It shows the extent of how the disaster affects live, how much damage it does, how it could end and how people would try and survive in that situation. The casualties and damage from the disaster also creates lots of opportunities for emotional moments.
I think that this theory would work really well in my trailer. Most horror movies actually follow this structure. First the characters are happy and living their lives, until an evil presence disrupts their live and they must put an end to this. Paranormal Activity is a classic example of this.
This narrative theory usually focuses more on the events of the disruption; not the characters. The disruption stage is the perfect opportunity to introduce the horror and scary creatures, which the main character must escape from.
