Plot and relation to the story

The film follows Dr. Henry Armitage, an expert in the occult, who goes to the old Whateley manor in Dunwich looking for Nancy Wagner, a student who went missing the previous night. He and Elizabeth, a friend and classmate of Nancy's, are turned away by Wilbur, the family's insidious heir, who has plans for the young girl. Through conversations with the locals, Armitage unearths the Whateleys' darkest secret, as well as a great evil.¹ In the film's opening, Armitage hands the Necronomicon, a book describing how to release the Old Ones, to Nancy, one of his students; Wilbur asks to look at it and reads from it.⁸ The film keeps Lovecraft's entity Yog-Sothoth by name, along with the Necronomicon and the Old Ones, while bending the story toward a more conventional witchcraft-movie plot.⁹

Changes from the story. The film modernizes the 1928 setting of Lovecraft's story to the late 1960s and alters several plot points: in the novella, Wilbur dies mid-story attempting to steal the Necronomicon from the Miskatonic University library, Armitage's two male sidekicks become the female roles of Nancy and Elizabeth, and the Whateley farmhouse is unkempt rather than a gothic mansion.¹⁰ The creature's rampage is conveyed largely through psychedelic posterized imagery and point-of-view shots rather than a shown monster.¹¹^•¹

Production

The project was announced in a September 12, 1968 Daily Variety item, which noted that Ray Russell would adapt the screenplay from Lovecraft's story. The finished film was written by fledgling screenwriters Henry Rosenbaum, Ronald Silkosky, and Curtis Hanson, with unrecorded contributions from AIP veterans Ray Russell and Charles Beaumont, who had written the script for Roger Corman's The Haunted Palace (1963), an adaptation of Lovecraft's The Case of Charles Dexter Ward.²^•⁵ The film marked Hanson's feature debut, credited as "Curtis Lee Hanson"; he later won an Academy Award for his work on L.A. Confidential (1997).³^•⁶

AIP and the Lovecraft cycle. The film came from producers James H. Nicholson and Samuel Z. Arkoff of American International Pictures, working with Roger Corman, and followed the success of AIP's cycle of Edgar Allan Poe adaptations.¹^•⁶ It was the third Lovecraft film adaptation, after The Haunted Palace (1963) and Die, Monster, Die! (1965), the latter Haller's adaptation of Lovecraft's "The Colour Out of Space."⁵^•⁷ Haller later claimed the film was inspired by the success of Rosemary's Baby, and the Turner Classic Movies account describes it as heavily influenced by that Polanski film and Ira Levin's source novel.⁶^•⁵

Cast

Sandra Dee played Nancy Wagner in her first adult role after years as a child and teen star. Dean Stockwell played Wilbur Whateley, whose performance the TCM account calls the center of what is good about the film, rivaling for sheer weirdness his celebrated comeback in David Lynch's Blue Velvet (1986). Ed Begley played Dr. Henry Armitage, with Lloyd Bochner as Dr. Cory and Sam Jaffe as Old Whateley. Talia Shire, then billed as Talia Coppola, made a brief appearance.¹^•⁵^•⁶

Release and reception

The film opened theatrically on January 14, 1970, in Chicago at McVickers Theater, grossing $30,000 in its first week.² It was initially rated "M" by the MPAA, and a July 1970 New York Times review cited a revised rating of "GP" (all ages admitted, parental guidance suggested).²

Critical reception has been mixed. On Rotten Tomatoes the film holds a 29% Tomatometer from 7 reviews and a 28% Popcornmeter from more than 2,500 ratings; the IMDb user rating is 5.4/10 from about 6,100 votes.¹^•⁴ Individual critics cited on the site include Ken Hanke of Mountain Xpress, who called it "pretty much botched Lovecraft adaptation," and Budd Wilkins of Slant Magazine, who called it "groovy and grotesque in equal measure."¹ The Oregonian, quoted by TCM, called it "a pretty good bad movie."⁵ Later assessments have been more favorable: the On Magazine review called it an "underrated classic" whose atmosphere captures Lovecraft wonderfully, and Comic Watch called it a successful adaptation praised for its psychedelic imagery.⁶^•¹¹

Legacy

The film's animated title sequence, created by a designer who cut his teeth working with Roger Corman, has been described as a powerful animated piece that gives the film a graphic elegance above its B-movie station.¹² The film remains available on streaming services, including Prime Video and Apple TV.¹
