The Dunwich Horror (1970) Timeline Explained – Every Event in Order

Nancy was targeted because Wilbur needed a vessel for his ritual to summon The Old Ones. Under hypnosis and drugs, Nancy was seduced on a clifftop altar and later prepared as a sacrificial offering. Her role was both to serve as the physical means to complete the ritual and to carry his child, continuing the Whateley bloodline.

Foreshadowing: Earlier, Armitage warns Nancy about Wilbur's dangerous lineage, foreshadowing his predatory interest in her.

The Necronomicon is a legendary forbidden book containing occult knowledge and rituals capable of summoning ancient cosmic entities known as The Old Ones. Wilbur steals it from Miskatonic University to perform the ritual that would bring his demonic father into the physical world. The book is so dangerous it exists in only one known copy.

Foreshadowing: Armitage's lecture at the beginning establishes the Necronomicon's power and danger, making Wilbur's obsession with obtaining it logical.

Lavinia Whateley gave birth to twins fathered by an unspecified entity. One child was stillborn, while the other became Wilbur Whateley. A second, monstrous twin was also born, a half-human creature that was locked away. Lavinia was institutionalized and aged dramatically, dying in the asylum during the events of the film. The traumatic childbirth set the family's cursed lineage in motion.

Foreshadowing: The opening scene shows a difficult birth with two elderly women and an old man watching, hinting at the twins' origin.

Wilbur Whateley is the human-looking twin, while his monstrous sibling was the stillborn-looking but living child from the same birth. The creature was hidden in a locked room within the Whateley house for years. When Elizabeth accidentally releases it, the monster escapes and goes on a killing spree through Dunwich before Wilbur's defeat.

Foreshadowing: Dr. Cory mentions that Lavinia delivered twins, with one child disappearing from records, hinting at the hidden twin's existence.

Dr. Armitage confronts Wilbur during the ritual by chanting reverse spells against the Necronomicon incantations. As Wilbur calls down his demonic father, a lightning strike hurls Wilbur into the sea, killing him and halting the summoning. Armitage's knowledge of the occult and the book's counter-rituals proves essential in stopping the ancient evil from being unleashed.

Foreshadowing: Armitage's lecture on the Necronomicon and his warnings about the Whateleys establish his expertise in the very forces Wilbur seeks to command.

Nancy emerges from the ritual physically unharmed but pregnant with Wilbur Whateley's child. This ending suggests the Whateley legacy cannot be so easily destroyed, the demonic bloodline continues through Nancy's unborn child. Despite Armitage and Cory declaring the Whateley line ended, the pregnancy implies the horror persists in a new form.

Foreshadowing: Wilbur's seduction of Nancy on the clifftop altar was part of his broader plan to continue his bloodline through both ritual and reproduction.

Old Whateley died during an argument with Wilbur over Nancy's disabled car. The confrontation became physical, and in the struggle, the elderly man fell down a flight of stairs to his death. Wilbur then attempted to move the body for a non-Christian burial, but the townsfolk intervened, refusing to let the desecration occur.

Foreshadowing: Tension between Wilbur and his grandfather has been building throughout the film as Wilbur's reckless actions threaten the family's already fragile position.

Elizabeth Hamilton inadvertently released Wilbur's monstrous twin creature from a locked room in the Whateley house. The creature immediately killed Elizabeth and escaped into Dunwich, where it went on a killing rampage. This half-human, half-something-else being was the result of the same birth that produced Wilbur.

Foreshadowing: Earlier revelations about Lavinia's twins and the missing second child set up the existence of this hidden creature.

Wilbur seeks to summon his demonic father, a member of The Old Ones, because he believes the arrival of this ancient cosmic entity will grant him immense power and fulfill his family's legacy of serving these beings. The ritual requires Nancy as a sacrificial vessel and the Necronomicon to complete the summoning. Wilbur sees this as the culmination of his bloodline's purpose.

Foreshadowing: The Whateley family's generations of occult practices and their connection to ancient evil foreshadow Wilbur's ultimate goal.

Wilbur approaches Nancy at Miskatonic University specifically because he knows she has access to the Necronomicon. His hypnotic gaze and charming demeanor are tools to gain her trust and ultimately access the book. He uses her to get to Dunwich, where he can use the Necronomicon for his ritual without interference.

Foreshadowing: Wilbur's immediate interest in the Necronomicon when he meets Nancy reveals his true motivation from their first encounter.
