Film genres explained: from thriller to rom-com

March 28, 2026 8 minute read Teasy Team

Genres are the language through which filmmakers and audiences communicate. They create expectations: when you go to see a horror film, you prepare to be scared; with a romantic comedy you expect laughs and to be moved. But genres are also much more than labels — they are the framework within which stories are told and broken. A guide through the colourful world of film genres.

The major genres

Drama

The broadest and most versatile genre. Drama focuses on emotional conflict and character development, without the emphatic elements of other genres. From The Shawshank Redemption to Marriage Story — drama is the foundation of the art of cinema. Many films are categorised as "drama plus something": a drama with thriller elements, a drama with a historical context.

Thriller

Tension is the key word. Thrillers keep audiences on the edge of their seats through danger, secrets and uncertainty. Subgenres are plentiful: the psychological thriller (Black Swan, Gone Girl), the legal thriller (A Few Good Men), the techno-thriller (Enemy of the State). The difference from horror: thrillers work through tension and realistic threat; horror through fear and the supernatural.

Horror

The genre of fear. Horror varies enormously: from the slasher (a masked killer pursuing victims, as in Halloween) to supernatural horror (The Conjuring), from psychological horror (Hereditary, Midsommar) to body horror (The Fly). The "elevated horror" of studio A24 has raised the genre to a new artistic level in recent years.

Action

Movement, combat and spectacle. Action films revolve around physical confrontations, chases and heroic deeds. The genre has various subgenres: martial arts (The Raid), action-adventure (Indiana Jones), military action (Apocalypse Now). The modern action blockbuster is inextricably linked to CGI and practical stunts.

Science Fiction

Exploration of the future, science and humanity. Science fiction asks the big questions: what makes us human, what is consciousness, what would technology do to society? From the utopian tradition (Star Trek) to dystopia (Children of Men, Blade Runner), from cosmic adventures (Interstellar) to nanotechnology (Annihilation).

Comedy

The most culturally specific genre — humour is not universal, after all. Subgenres are diverse: the romantic comedy (also known as "rom-com"), slapstick (physical humour, Charlie Chaplin), the screwball comedy (fast dialogue, eccentric situations), and dark comedy (humour around dark themes such as death or war).

Overview of subgenres and hybrids

  • Romantic comedy (rom-com): love, misunderstandings, happy ending — Notting Hill, When Harry Met Sally
  • Horror comedy: fear and laughter combined — Shaun of the Dead, Get Out
  • Action thriller: tension + spectacle — Die Hard, Mission: Impossible
  • Science fiction horror: alien or extraterrestrial threat — Alien, The Thing
  • Biopic: biographical drama about real people — Bohemian Rhapsody, Oppenheimer
  • Western: the Wild West, moral conflicts — The Good, the Bad and the Ugly
  • Musical: story told through songs — La La Land, West Side Story
  • Animation: a technique, not a genre — but often used as its own category

The rise of hybrid genres

The most interesting films of recent years are difficult to fit into a single box. Get Out (2017) is horror and social satire and thriller. Parasite (2019) begins as a dark comedy, develops into a thriller and ends as drama. Everything Everywhere All at Once (2022) combines science fiction, martial arts, emotional drama and absurdist comedy in one film that won the Oscar for Best Picture.

This genre-crossing approach reflects a broader trend: audiences and filmmakers are tired of formulas. The most memorable films are those that set up expectations — and then break them in a meaningful way.

Genres in cinema programming

For cinema programmers, genres are essential planning tools. A cinema that knows its audience knows which genres land well. An arthouse cinema programmes more drama and international films; a multiplex focuses on action, animation and commercial horror. Genres also determine marketing strategy: every trailer communicates the genre of a film within a few seconds — and with it, the promise to the audience.

A good trailer for a thriller uses tension-building, dark imagery and percussive music. A rom-com trailer features light music, funny clips and a glimpse of romantic tension. It is the language of genres, translated visually.

Genre as a contract with the audience

Ultimately, a genre is a promise. When you buy a cinema ticket for a horror film, you want to be scared. When you choose a romantic comedy, you want to feel good. That contract is the foundation of the relationship between a film and its viewer. The most beautiful films are those that honour that contract — and then do something with it that you never expected.
