The document analyzes the visual elements and techniques used in movie posters for thriller films. It discusses how the use of dark colors, shadowing on characters, off-camera positioning that creates mystery, bold fonts, and stereotypical icons like knives and flames are employed to convey a sense of suspense, danger, and unease to hint at the thriller genre. Elements like isolated settings on islands also play on connotations of being trapped. Intimidating eye contact with the audience and different styled title fonts that stand out are described as typical techniques used to put viewers on edge.
