Nancy (Sandra Dee, who spends half this film in a state or orgasm) falls for creepy Wilbur (Dean Stockwell, still making amends for "The Boy With Green Hair"). Wilbur is a student of the occult and desires to study the Necronomicon, kept in the university library. Wilbur, the last descendant of an occultic family, has plans for the beautiful and vulnerable Nancy, and easily puts her in a trance and brings her back to his home. Nancy's boss, Professor Armitage (Ed Begley) and her beautiful friend, Elizabeth (Donna Baccala, pictured above right) will attempt to get her back, with no success. In fact, Elizabeth will be raped and mutilated by a tentacled monster as a reward for her efforts. Wilbur gets down to business and immediately turns Nancy into a vessel for sex. Most of the carnal relations are on an altar at the ruins of weird temple (...we've all been there, done that...).
Nancy is aroused by the sexual relations and is totally under Wilbur's power. Meanwhile, a monster locked in Wilbur's closet (the same one that feasts on Elizabeth) busts out of its captivity. Professor Armitage, also an expert on the Necronomicon, figures out what Wilbur is up to. Wilbur will use the Necronomicon to bring creatures from another dimension to Earth, and those creatures will wipe out mankind. Exactly what is Nancy's destiny in this plan? Professor Armitage and the town doctor (Lloyd Bochner) rush to the altar to save Nancy and mankind....but is it too late? Remember, this is a Roger Corman film, so Nancy's fate may not be a surprise to you.
A cool monster, an erotic performance by Sandra Dee, lots of orgasms, and an overly dramatic musical score will make your day while watching "The Dunwich Horror." Cheap special effects act only to enhance this B movie in our eyes. Ominous and serious at times, playful and campy at times, this film will surely entertain. Available on Netflix.
