Suspense

A horror film is a film that seeks to elicit fear for entertainment purposes. Initially inspired by literature from authors like Edgar Allan Poe, Bram Stoker, and Mary Shelley, horror has existed as a film genre for more than a century. The macabre and the supernatural are frequent themes. Horror may also overlap with the fantasy, supernatural fiction, and thriller genres.

A mystery film is a genre of film that revolves around the solution of a problem or a crime. It focuses on the efforts of the detective, private investigator or amateur sleuth to solve the mysterious circumstances of an issue by means of clues, investigation, and clever deduction.

The conspiracy thriller (or paranoid thriller) is a subgenre of thriller fiction. The protagonists of conspiracy thrillers are often journalists or amateur investigators who find themselves (often inadvertently) pulling on a small thread which unravels a vast conspiracy that ultimately goes "all the way to the top." The complexities of historical fact are recast as a morality play in which bad people cause bad events, and good people identify and defeat them. Conspiracies are often played out as "man-in-peril" (or "woman-in-peril") stories, or yield quest narratives similar to those found in whodunits and detective stories.

Korean horror films have been around since the early years of Korean cinema, however, it was not until the late 1990s that the genre began to experience a renewal. Many of the Korean horror films tend to focus on the suffering and the anguish of characters rather than focus on the explicit "blood and guts" aspect of horror. Korean horror features many of the same motifs, themes, and imagery as Japanese horror.

Japanese horror (also known as J-horror) is horror fiction arising from popular culture in Japan, generally noted for its unique thematic and conventional treatment of the horror genre differing from the traditional Western representation of horror. Mediums in which Japanese horror fiction is showcased include literature, anime and film, video games, and artwork. Japanese horror tends to focus on psychological horror, tension building (suspense), and supernatural horror, particularly involving ghosts (yūrei) and poltergeists. Other Japanese horror fiction contains themes of folk religion such as possession, exorcism, shamanism, precognition, and yōkai.

The legal thriller is a subgenre of thriller and crime fiction in which the major characters are lawyers and their employees. The system of justice itself is always a major part of these works, at times almost functioning as one of the characters. In this way, the legal system provides the framework for the legal thriller much as the system of modern police work does for the police procedural.

A splatter film is a subgenre of horror film that deliberately focuses on graphic portrayals of gore and graphic violence. These films, usually through the use of special effects, display a fascination with the vulnerability of the human body and the theatricality of its mutilation. The term "splatter cinema" was coined by George A. Romero to describe his film Dawn of the Dead, though Dawn of the Dead is generally considered by critics to have higher aspirations, such as social commentary, than to be simply exploitative for its own sake.

Spy fiction, a genre of literature involving espionage as an important context or plot device, emerged in the early twentieth century, inspired by rivalries and intrigues between the major powers, and the establishment of modern intelligence agencies. It was given new impetus by the development of fascism and communism in the lead-up to World War II, continued to develop during the Cold War, and received a fresh impetus from the emergence of rogue states, international criminal organizations, global terrorist networks, maritime piracy and technological sabotage and espionage as potent threats to Western societies. As a genre, spy fiction is thematically related to the novel of adventure (The Prisoner of Zenda, 1894, The Scarlet Pimpernel, 1905), the thriller (such as the works of Edgar Wallace) and the politico-military thriller (The Schirmer Inheritance, 1953, The Quiet American, 1955).

A disaster film or disaster movie is a film genre that has an impending or ongoing disaster as its subject and primary plot device. Such disasters include natural disasters such as floods, earthquakes, tsunamis or asteroid collisions, accidents such as shipwrecks or airplane crashes, or calamities like worldwide disease pandemics. A subgenre of action films, these films usually feature some degree of build-up, the disaster itself, and sometimes the aftermath, usually from the point of view of specific individual characters or their families or portraying the survival tactics of different people.

Erotic thriller is a film subgenre defined as a thriller with a thematic basis in illicit romance or erotic fantasy. Most erotic thrillers contain scenes of softcore sex and nudity, but the frequency and explicitness of those scenes varies.
