The document discusses several technical conventions commonly used in thriller films to create suspense and tension. It describes how camerawork such as tracking shots, point-of-view shots, and close-ups follow the action and involve the audience. Sound techniques like silence, exaggerated sounds, and tense music are used to create an eerie atmosphere. Elements of mise-en-scene like low key lighting, chiaroscuro lighting effects, and manipulated color are employed to generate mystery. Fast-paced editing, jump cuts, parallel editing, and obtrusive editing work to build a sense of danger, confusion, and pace.
