A film genre is a stylistic or thematic category for motion pictures based on similarities either in the narrative elements, aesthetic approach, or the emotional response to the film.

Drawing heavily from the theories of literary-genre criticism, film genres are usually delineated by "conventions, iconography, settings, narratives, characters and actors". One can also classify films by the tone, theme/topic, mood, format, target audience, or budget.Hayward, Susan. "Genre/Sub-genre" in Cinema Studies: The Key Concepts (Third Edition). Routledge, 2006. p. 185–192 These characteristics are most evident in genre films, which are "commercial feature films [that], through repetition and variation, tell familiar stories with familiar characters and familiar situations" in a given genre.Grant, Barry Keith. Film Genre: From Iconography to Ideology. Wallflower Press, 2007. p. 1

A film's genre will influence the use of filmmaking styles and techniques, such as the use of flashbacks and low-key lighting in film noir; tight framing in horror films; or fonts that look like rough-hewn logs for the titles of Western films.Grant, Barry Keith. Film Genre: From Iconography to Ideology. Wallflower Press, 2007. p. 11 In addition, genres have associated film scoring conventions, such as lush string orchestras for romantic melodramas or electronic music for science fiction films. Genre also affects how films are broadcast on television, advertised, and organized in video rental stores.

Alan Williams distinguishes three main genre categories: narrative, avant-garde, and documentary.Alan Williams, "Is a Radical Genre Criticism Possible?" Quarterly Review of Film Studies 9, no. 2 (Spring 1984): 121–2

With the proliferation of particular genres, film subgenres can also emerge: the legal drama, for example, is a sub-genre of drama that includes courtroom- and trial-focused films. Subgenres are often a mixture of two separate genres; genres can also merge with seemingly unrelated ones to form hybrid genres, where popular combinations include the romantic comedy and the action comedy film. Broader examples include the docufiction and docudrama, which merge the basic categories of fiction and non-fiction (documentary).Judith Butler and genre theory.

Genres are not fixed; they change and evolve over time, and some genres may largely disappear (for example, the melodrama). Not only does genre refer to a type of film or its category, a key role is also played by the expectations of an audience about a film, as well as institutional discourses that create generic structures.

Overview Characteristics Characteristics of particular genres are most evident in genre films, which are "commercial feature films [that], through repetition and variation, tell familiar stories with familiar characters and familiar situations" in a given genre.

Drawing heavily from the theories of literary-genre criticism, film genres are usually delineated by conventions, iconography, narratives, formats, characters, and actors, all of which can vary according to the genre. In terms of standard or "stock" characters, those in film noir, for example, include the femme fataleGrant, Barry Keith. Film Genre: From Iconography to Ideology. Wallflower Press, 2007. p. 17 and the "hardboiled" detective; while those in Westerns, stock characters include the schoolmarm and the gunslinger. Regarding actors, some may acquire a reputation linked to a single genre, such as John Wayne (the Western) or Fred Astaire (the musical).Grant, Barry Keith. Film Genre: From Iconography to Ideology. Wallflower Press, 2007. p. 18 Some genres have been characterized or known to use particular formats, which refers to the way in which films are shot (e.g., 35 mm, 16 mm or 8 mm) or the manner of presentation (e.g., anamorphic widescreen).

Genres can also be classified by more inherent characteristics (usually implied in their names), such as settings, theme/topic, mood, target audience, or budget/type of production.

The setting is the environment—including both time and geographic location—in which the story and action take place (e.g., present day or historical period; Earth or outer-space; urban or rural, etc.). Genres that are particularly concerned with this element include the historical drama, war film, Western, and space-opera, the names of which all denote particular settings. The theme or topic refers to the issues or concepts that the film revolves around; for example, the science fiction film, sports film, and crime film. The mood is the emotional tone of the film, as implied in the names of the comedy film, horror film, or 'tearjerker'. Genres informed by particular target audience(s) include children's film, teen film, woman's film, and "chick flick". Genres characterized by the type of production include the blockbuster, independent film, and low-budget film, such as the B movie (commercial) or amateur film (non-commercial).

Screenwriters, in particular, often organize their stories by genre, focusing their attention on three specific aspects: atmosphere, character, and story. A film's atmosphere includes costumes, props, locations, and the visceral experiences created for the audience. Aspects of character include archetypes, stock characters, and the goals and motivations of the central characters. Some story considerations for screenwriters, as they relate to genre, include theme, tent-pole scenes, and how the rhythm of characters' perspective shift from scene to scene.

Much like film noir, its recognition as a genre with specific formal and thematic characteristics came retrospectively, and was driven by a 1970s critical re-evaluation of the films of Douglas Sirk, who came to be considered the greatest exponent of melodrama. The canonical form of melodrama, associated with the 1950s Hollywood films of Sirk, Vincente Minnelli, Nicholas Ray, George Cukor, Billy Wilder and Joseph Losey, among others, is known as "family melodrama" and centers on middle-class family conflicts, often generational, within contexts of social mobility and emotional trauma. Unlike drama, melodrama functions as a code that opposes realism, exaggerating the conventions of representation and mise-en-scène to depict the emotional states of the characters.
