Narrative/Structuralist theories that could be applied to our trailer

Binary opposition: 

This is a sense of difference or conflict that is provided for the audience to create the a meaning and understanding which is generated by the difference that is shown.

We could apply this theory to our trailer. Using binary oppositions would give us the chance to be more positive that the audience would understand it more better.
For example, the villain/mystery character would be shown as a strong, reticent and in shadows whereas the victim would be weak, emotional and shown in bright light with no shadows. This would differentiate the characters and give the audience a more better understanding of who is who and what are their roles. This theory would be perfect for our trailer as the genre being horror would mean demonstrating more shadows and aggressive behaviour.
Binary oppositions include passive or aggressive, weak or strong, responds or initiates, female or male and neurotic or balanced. We would be using most of these as these oppositions would create signs that would mean different things to the audience. Binary oppositions would help us in making our trailer more understandable and representable without audience being unsure of what it is which could lead them to not wanting to watch it.

Other theory that could be combined with the binary opposition theory to our product would be Roland Barthe's theory of enigma codes. This would be very useful for our trailer as we will not be establishing the full clear story as it is only a trailer and a trailer should not include the full story. But we will be using props that would link in engaging the audience and keeping them interested. This theory suggests that the teaser shown would make the audience wanting to know more about what the trailer is about.

Theory of enigma codes by Roland Barthe 

Hermeneutic Codes:
This theory would be applied to our trailer as we would not be showing all the elements of the story. This theory suggests that not all the story should be unrelieved until the end as this would give more chance of the audience to be engaged all the way through.
Proaireutic Codes:
This could be applied to our trailer as the action that would be shown on the screen would need to be linked in order to make sense and give a clear understanding to the audience. We would apply this so the audience know what the character is going to do as they have seen an action that would be linked to another scene.
Semantic Codes:
For our trailer we would add additional meaning by scripting the right amount of dialogues, scenes and costume. This would give more opportunity to the audience to have a wider denotation of the trailer we will make.

Vladimir Propp's Character Theory 

This theory suggest that there is always some characters in the film that make the story. There is always a hero, a villain, a helper, a victim, a parental figure, a heroine, a mentor and a donor.
This creates a good story and our trailer would come in this theory as we will have a victim which would be the hero also. Other characters would be added in our trailer which are suggested in this theory therefore this theory would be applied to our trailer.

Structuralism 

This theory says that there is a normality at the start of the film; equilibrium, a disturbed part; disequilibrium and new equilibrium where everything goes back to normal resulting in a happy ending.
This theory would not be useful and applied to our trailer as a trailer is not a full film and is meant to interest the audience and give them the opportunity to denotate the trailer as they want to. Therefore if we apply structuralism to our trailer, it would not be an interesting trailer, it would turn in to a short film instead. For this reason this theory would mislead our product to being something that we do not intend to produce.
