In Louisianna, the thirty-five year old single mother Lavina (Lauren Michele) delivers a baby boy and a monster in the evil Whateley House. Ten years later, Dr. Henry Armitage (Dean Stockwell) and his assistant Professor Fay Morgan (Sarah Lieving) discover that the page 751 of every copy of the Necronomicon is missing and The Black Brotherhood has summoned the gate keeper Yog Sothoth to leave the portal opened to the demons and ancient gods. They invite the arrogant and skeptical Professor Walter Rice (Griff Furst) that can translate the Necronomicon to help them to seek the book. Meanwhile Lavina's son Wilbur Whateley (Jeffrey Combs) ages very fast and seeks the missing page to open the portal.
"The Dunwich Horror" is a cheesy low-budget horror movie that has an awful screenplay associated to terrible acting and poor special effects. Dean Stockwell and the cult-actor Jeffrey Combs are wasted in this forgettable flick. The romance of Fay and Rice is quite ridiculous and out of the context of the plot. My vote is three.
Title (Brazil): "Bruxas" ("Witches")
