Hereditary has received some of the most passionate reviews at this year’s Sundance film festival – and it’s already scored a cool 100% on Rotten Tomatoes.

Thrillist led the hype of the film in its review, claiming that: “The screams in the theatre were almost as frightening as what was on screen,” while USA Today called it “the most insane horror movie in years.”

For a while, we resisted the hype: how scary can another film about a haunted house really be, after all?

Well, after seeing the latest trailer, we’re more than prepared to eat our words, because it looks abso-bloody-lutely terrifying.

Check it out:

Hmm. It seems safe to say that dollhouses will never be the same again, eh? Or pigeons. Or grandparents. 

Or, you know, anything. 

Starring Toni Collette, Gabriel Byrne, Alex Wolff, and Milly Shapiro, the film follows a family as they grieve for their late grandmother.

“When Ellen, the matriarch of the Graham family, passes away, her daughter’s family begins to unravel cryptic and increasingly terrifying secrets about their ancestry,” reads the official synopsis.

“The more they discover, the more they find themselves trying to outrun the sinister fate they seem to have inherited.”

It continues: “Making his feature debut, writer-director Ari Aster unleashes a nightmare vision of a domestic breakdown that exhibits the craft and precision of a nascent auteur, transforming a familial tragedy into something ominous and deeply disquieting, and pushing the horror movie into chilling new terrain with its shattering portrait of heritage gone to hell.”

Earlier this year, the first trailer, which can be seen above, saw Annie (Collette) giving a eulogy at her mother’s funeral, in which she describes her as a “private” and “secretive” person.

What followed was… well, it was nightmarish and baffling, all at once. A child scribbled gargoyle-esque images like there’s no tomorrow. A man cut the head off a pigeon. Someone’s body was engulfed in flames. Annie gets really, really into her creepy figurine obsession.

You get the picture. Familial tragedy, heritage gone to hell… that sort of thing. No wonder people are calling it “a new generation’s The Exorcist”, eh?

Hereditary opens everywhere on 15 June. Based on the trailer alone, we recommend catching up on your slumber before you got see it: we have a feeling you’ll be facing many sleepless nights once the credits roll.
