A thriller uses suspense, tension, and excitement through elements like plot twists and cliffhangers to keep audiences engaged. Technical elements include quick cuts and changes in camera angles to build tension. Mise-en-scene features include props like weapons and costumes with dark colors. Sound design uses silence and screams to suggest fear. The narrative structure builds complications until a climax and resolution. Camera techniques like close-ups, tracking shots, and rule of thirds compositions are employed.
