The thriller genre encompasses numerous subgenres that are characterized by creating feelings of suspense, excitement, and anxiety in viewers. Common conventions of thrillers include withholding important information from viewers, using plot twists and cliffhangers, and settings that create a suspenseful atmosphere. Cinematography techniques like close-ups and tracking shots are employed to emphasize suspense and emotion. Modern thrillers continue to follow these conventions to build suspense through the use of film techniques and literary devices.
