A thriller is a film genre that uses suspense and anticipation to keep audiences alert and on the edge of their seats. Thrillers often involve a protagonist trying to solve a mystery or escape from danger. They are typically set in isolated locations like woods or homes. Common characters include criminals, stalkers, victims, police, and deranged individuals. Thrillers usually center around crimes or mysterious incidents, with plot twists to maintain engagement. Stylistically, thrillers employ close-ups, low lighting, synthesized sounds, and editing techniques to build tension and suspense.
