Dagon is a Spanish horror film directed by Stuart Gordon, known for his work in the genre with films like Re-Animator and From Beyond. The film is loosely based on the works of H.P. Lovecraft, particularly his stories involving ancient gods and cosmic horror.

The plot follows a young couple, Paul (Xabier Elorriaga) and Barbara (Mara Martínez), who are sailing off the coast of Spain when their boat encounters a storm. They are forced to dock in a remote fishing village to seek help. Upon arriving, they find the village eerily deserted, with strange symbols and a pervasive sense of unease.

As Paul and Barbara explore the village, they discover that the residents have made a pact with a monstrous sea deity named Dagon. The villagers are part of a cult that worships this ancient entity, and they are willing to sacrifice outsiders to ensure their continued favor. The film delves into themes of forbidden rituals, human sacrifice, and the terrifying realization that the village is not what it seems.

Dagon combines elements of supernatural horror with Lovecraftian mythology, creating a tense and unsettling atmosphere. The film features unsettling visuals, including the grotesque appearance of the sea creature and the disturbing rituals performed by the villagers. It also incorporates practical effects and creature designs that add to the sense of dread.

The film is praised for its ability to evoke a sense of claustrophobic terror and its effective use of Lovecraftian themes to create an atmosphere of cosmic horror. Dagon is a notable entry in the horror genre for its homage to Lovecraft’s work and its ability to generate genuine fear through its unsettling narrative and visual style.
