Thriller films aim to build tension and suspense by placing protagonists in difficult situations involving crimes like murder that they must solve. Common narrative elements include protagonists confronting crimes or evil schemes, multiple chase and fight scenes, and a final showdown between good and evil. Typical characters include a main protagonist like a detective solving a disruption, the main antagonist committing crimes, and supporting characters like detectives, police, victims, henchmen, and love interests. While most thrillers follow this structure, there are also subgenres like action, crime, psychological, and romantic thrillers that vary the focus, pace, and type of suspense involved.
