The document discusses structuralism and how it relates to analyzing the Halloween (1978) movie trailer. It provides examples of how structuralism explores how meaning is constructed through symbols and signs within a culture. It then analyzes the Halloween trailer based on its iconography, use of structuralism, and adherence to thematic paradigms of the slasher horror genre. Key elements analyzed include the masked killer's hidden identity, use of a knife as a symbol of their evil nature, and how the non-diegetic music builds tension. It also examines how the relationship between the murderer's two identities as a child and adult fit the tropes of a psychopathic slasher villain.
