The document summarizes research on trailers and posters for psychological thriller films. It analyzes the overall structures, sounds, and visual elements of trailers for Get Out and We Need to Talk About Kevin. It also analyzes posters for Silence of the Lambs and Black Swan. Key findings include how the trailers use tension-building music and editing to portray the films' psychological elements without revealing full plots. Common visual techniques identified are use of color symbolism and compositional elements to characterize figures and hint at themes. The analysis will inform the creator's own production work through suggestive imagery, sound design, and portrayal of characters' emotions.
