One of the most buzzed-about films at the 2018 Sundance film festival was Ari Aster’s unsettling writing and directing debut Hereditary, a horror film starring Toni Collette, Gabriel Byrne, Alex Wolff, and Milly Shapiro as a family haunted by their past. Or more accurately, haunted by their creepy dead grandmother. Or more accurately than that, haunted by things that should not be spoiled. Critics nearly universally praised Hereditary as shocking and terrifying, leading to some skeptical backlash from horror fans who felt burned by similar advance praise for films like The Witch and It Comes At Night, two extremely tense horror films in which not a whole lot ultimately happens.

Well, now Hereditary has its first trailer, which makes it pretty evident that this film has a lot more grim action than either of those movies. Judge for yourself. The best thing about this trailer is that it’s cleverly misleading in all the right ways, so even if you think you’re being spoiled about a plot point, you’re probably not — which won’t keep you from getting the gist and tone of the movie, but will leave a lot of surprises.

Hereditary is set for wide theatrical release on June 28th, 2018.
