EXCLUSIVE: A24 is re-teaming with Hereditary helmer Ari Aster to produce and fully finance his next untitled horror project, sources said. The film will be A24’s largest production to date, with an expected production start of late summer/early fall 2018. Lars Knudsen and B Reel will also produce.

The plot is being kept under wraps though it follows a young woman who reluctantly joins her boyfriend on a summer trip where things quickly go awry. A24 is currently in process of casting the film.

All this comes as A24 prepares for the June 8 wide release of Aster’s anticipated directorial debut Hereditary. The film, which stars Toni Collette and Gabriel Byrne, premiered in last Sundance Film Festival’s Midnight section to unanimously positive reviews. Aster’s previous credits include the shorts The Strange Thing About the Johnsons and Munchausen, both of which he wrote and directed.

Hereditary

Hereditary centers on the Graham family, which begins to unravel following the death of their reclusive grandmother. Even after she’s gone, the matriarch still casts a dark shadow over the family — especially her loner teenage granddaughter, Charlie, with whom she always had an unusual fascination. As an overwhelming terror takes over their household, their peaceful existence is ripped apart, forcing their mother to explore a darker realm in order to escape the unfortunate fate they’ve inherited.

Aster is repped by WME, manager Kevin Rowe and Bloom Hergott.
