The American horror director whose 2018 debut Hereditary established him almost immediately as one of the most-distinctive working filmmakers of his generation. Four films, four maximalist projects.
Ari Aster was 31 when Hereditary (2018) premiered at Sundance. The film, his directorial debut, established him almost immediately as one of the most-significant working American directors of his generation. He has subsequently directed Midsommar (2019), Beau Is Afraid (2023), and Eddington (2025). All four films have been A24 productions; Aster has not, as of 2026, worked with any other major distributor.
His filmography is, by structural design, maximalist. The films are long (Beau Is Afraid runs 179 minutes), tonally ambitious (the films attempt psychological, horror, comedic, and dramatic registers within single sequences), and visually elaborate (Aster's working approach involves extensive pre-production storyboarding and detailed production design across every frame). The reception across his four films has been increasingly polarised — Hereditary was nearly universally praised; Beau Is Afraid divided critics; Eddington's 2025 release produced one of the most-discussed critical splits of recent years.
What is not in dispute is that Aster's work, regardless of individual-film judgments, is recognisably his. The specific visual approach, the slow-build dread, the willingness to extend running times beyond conventional commercial expectations, and the recurring thematic concerns with family-of-origin trauma make the films legibly Aster productions.
Aster's visual signature is the static wide composition — a camera that holds in place while the action plays out within the frame, with the entire visible space available for the audience to scan for unsettling details. The technique is on display throughout Hereditary; the famous family-portrait dollhouse shots, the dinner-table sequences, the séance scenes are all structured this way.
What the technique requires of the audience is patient looking. The audience must, in each held frame, work out where to focus attention. The films often plant unsettling details in the periphery — a face in the background, a small movement at the edge of the shot — that conventional cinematic framing would have centred. The technique has been imitated extensively across subsequent A24 horror but few directors have committed to it as completely as Aster.
All four Aster features are, at the structural level, about family-of-origin trauma. Hereditary is about an inherited demonic cult that has selected the protagonist's family across multiple generations. Midsommar is about a young woman whose family has been destroyed by her sister's murder-suicide and who travels to a commune that promises a new family structure. Beau Is Afraid is about a 50-year-old man whose mother's psychological control has shaped every aspect of his life. Eddington's 2025 western political-thriller framing extends the family-trauma concern into the broader American national context.
Aster has spoken across multiple interviews about the films as personal material. The recurring concern is not, structurally, autobiographical — Aster is not depicting his own family. The concern is what he calls 'the family as the place where the wound was made.' The films treat family as the dramatic situation that produces the broader horror or catastrophe that the rest of the film unfolds.
Aster's films have, across the four-feature run, increased in scale and tonal ambition. Hereditary (127 minutes) is the most-restrained. Midsommar (147 minutes for the theatrical cut; 171 minutes for the director's cut) extended the runtime and added the daylight-horror experiment that distinguished it from conventional supernatural horror. Beau Is Afraid (179 minutes) attempted to combine three distinct tonal registers within a single film. Eddington (2025) is reportedly Aster's longest and most-tonally-elaborate work.
The increasing maximalism has been argued about. Defenders argue that Aster's filmmaking is genuinely ambitious in ways that contemporary American cinema does not routinely permit — that the long runtimes and tonal range are the films' substance rather than self-indulgence. Critics argue that each subsequent film has been more-undisciplined than the last, and that the Hereditary debut remains his most-controlled work. Both readings have textual support. The debate will likely continue as Aster's subsequent work develops.
If you've never watched a Aster film:
Roman Polanski (particularly Rosemary's Baby and The Tenant), Robert Altman, the 1970s American horror tradition (especially Don't Look Now), David Lynch, and the broader European art-cinema tradition. Aster has cited Hereditary's tonal register as deliberately drawing on Rosemary's Baby's slow-build paranoia.
