Thriller is a genre of literature, film, and television that uses suspense, tension, and excitement as the main elements. The primary subgenre is psychological thrillers. After the assassination of President Kennedy, political thriller and paranoid thriller films became very popular.
The brightest examples of thrillers are the Hitchcock’s movies.The cover-up of important information from the viewer and fight/chase scenes are common methods in all of the thriller subgenres, although each subgenre has its own characteristics and methods.
Common methods in crime thrillers are mainly ransoms, captivities, heists, revenge, kidnappings. More common in mystery thrillers are investigations and the whodunit technique. Common elements in psychological thrillers are mind games, psychological themes, stalking, confinement/deathtraps, horror-of-personality, and obsession.
Elements such as conspiracy theories, false accusations, paranoia, and sometimes action are common in paranoid thrillers. some argue, though, that the thriller genre is simply a pseudonym for the horror genre, both using suspense and atmosphere to cause feelings of dread in their audiences.
"Homer's Odyssey is one of the oldest stories in the Western world and is regarded as an early prototype of the thriller." A thriller is villain-driven plot, whereby he presents obstacles that the hero must overcome.
