The document analyzes the visual, audio, narrative, action, and technical codes used in three film trailers:
1) All three trailers use fade-to-black transitions between shots to quickly showcase extracts from the films while maintaining pace.
2) They all employ the horror genre convention of using white costumes to connote innocence in some characters or cleanliness in others.
3) Each establishes disequilibrium early by placing the protagonist in a new unfamiliar environment like a house, island, or village to experience the unknown.
4) A community acts as an auxiliary antagonist in The Woman in Black and Shutter Island trailers.
