A thriller is a genre found in literature, movies, and television that uses suspense to keep audiences wondering what will happen next. Thrillers typically involve crimes or horror and feature extraordinary things happening to ordinary people. Thrillers are normally marketed toward late teens to early thirties who enjoy psychological movies and like to be fully engaged in the movie experience. Conventions of thrillers include dark color schemes, themes of isolation, props like guns to create tension, and constant twists in the plot. Thrillers differ from horrors in that they focus more on realistic reactions and the victim's perspective through suspense, while horrors emphasize graphic violence for its own sake.
