Annie Graham Is A Good Mother In Ari Aster’s HEREDITARY For Mothers Day, Chad Collins looks at Toni Collette's portrayal of Annie Graham in HEREDITARY! Annie Graham (Toni Collette) is a good mother. In Ari Aster’s sensational, spellbinding, almost criminally scary debut Hereditary, matriarch Annie Graham is ostensibly anything but. A living, breathing testament to the generational linkage of trauma and illness, the Graham family haunting is best exemplified by her slow unraveling. She screams in Oscar-caliber fashion, berates her living son Peter (Alex Wolff) as though it’s congenital to her being, and is no less a terrifying specter in that house than the ghost of deceased daughter, Charlie (Milly Shapiro). Annie Graham, at first glance, is not a good mother, but a bad one.
