How does The Crazies relate to the four media theorists?

Tzvetan Todorov
Todorov was the theorist that suggested that all movies start with an equilibrium (normality) and this is where opposing forces are in perfect symmetry and balance, this is then disturbed by something bad. In the Crazies this is when the man is walking over on the baseball game with the gun in his hand, the officer then shoots him but this is dramatic as you can tell that things like this dont ever happen in this little town. All events continue with the equilibrium out of balance until the end when they start walking away from the town that has been bombed

Vladimir Propp 
Propp looked at 100's of folk tales to see what structures they shared if any, he found that they mainly share 8 character roles and in the case of The Crazies this is how they relate.
The Villain - US Government/Zombies
The Hero - The Sheriff
The Donor - The Sheriff's wife
The Helper - The Deputy Sheriff
The Princess - The Sheriff's wife
Her Father - N/A
The Dispatcher - N/A
The False Hero - The Army

Claude Levi-Strauss
Strauss suggests that most films are based upon binary oppositions almost like that every reaction has an exact opposing reaction. In the crazies this is true somewhat because the Sheriff is Good and he is a law enforcer and the zombies are bad, But the government are also bad and are supposedly on the same. Day and Night are the same in this movie as murdering take place in the day and the night.

Bordwell and Thompson
These theorists suggest that everything in the narrative is important even if it isn't suggested or explained in the story. Its everything that makes the story rich and full. In the Crazies where we see the plane in the river, we don't know why its there or how it got there all we know is that its very important in the story and even though we don't see what happened about it or anything else surrounding it we know its important.
