Hereditary

Hereditary is Ari Aster’s 2018 feature debut, a supernatural horror drama centered on the Graham family after the death of its secretive matriarch. Toni Collette plays Annie, a miniature artist whose grief and family history begin to expose disturbing patterns; Gabriel Byrne, Alex Wolff and Milly Shapiro play her husband and children. Written and directed by Aster and released by A24, the film uses domestic conflict, carefully framed spaces and sustained dread to connect inherited trauma with an increasingly explicit occult mystery. It premiered at the 2018 Sundance Film Festival before its commercial U.S. theatrical release on June 8, 2018. This page refers to Aster’s original feature, not similarly titled shorts or television episodes. The carefully built miniatures inside Annie’s studio mirror the film’s emphasis on control, observation and predetermined roles.
