Which A24 horror film centers on a Swedish midsummer festival?

The A24 horror film centered on a Swedish midsummer festival is *Midsommar*.

Written and directed by Ari Aster, the 2019 film follows Dani, Christian, and their friends after they travel to Sweden at the invitation of Pelle, a Swedish friend. They arrive at the Hårga, an isolated commune in Hälsingland, for a nine-day midsummer celebration that gradually reveals disturbing rituals and communal violence.

Although much of the film unfolds in bright daylight, its folk-horror atmosphere comes from the collision between picturesque traditions and horrifying behavior. The festival is presented as occurring only once every 90 years, while the visitors’ strained relationships—especially Dani and Christian’s deteriorating partnership—form the emotional core.

*Midsommar* is often grouped with A24’s best-known horror releases, including *Hereditary*, Aster’s earlier feature. The film was shot mainly around Budapest rather than in Sweden, despite its Swedish setting, and its theatrical release was distributed in the United States by A24.
