This document discusses the codes and conventions commonly used in thriller genre films. It notes that mise-en-scene often uses normal clothing, low lighting, dark color palettes, and isolated settings. Cinematography employs close-ups, angle shots, tracking, panning, and point-of-view shots. Editing techniques include elliptical editing to remove unnecessary shots, parallel editing to show character divergence, and flashbacks/forwards. Sound is also important, using spooky music, epic music, sound effects, and voiceovers/dialogue to convey tension and realism.
