"Cold Skin" is a 2017 atmospheric horror film directed by Xavier Gens, set on a remote island in the early 20th century. It follows a weather observer who encounters strange creatures and struggles for survival against both them and his own isolation. The film is praised for its unique premise, strong performances, particularly by David Oakes and Ray Stevenson, and its haunting visuals. While it may not appeal to everyone due to its slow pacing and niche genre, it offers a blend of horror, psychological tension, and existential themes that can be intriguing for fans of atmospheric cinema.

At the end of "Cold Skin," the protagonist, a lighthouse keeper named Friend, confronts the monstrous creatures known as the Amphibians. After a climactic battle, he realizes the futility of fighting and instead chooses to coexist with the creatures, reflecting on humanity's struggles with isolation and connection. The film concludes ambiguously, with Friend accepting his fate on the remote island, hinting at themes of survival and the blurred lines between humanity and monstrosity.

"Cold Skin" was filmed on the island of Lanzarote, which is part of the Canary Islands, Spain. The island's unique volcanic landscapes provided a fitting backdrop for the film's eerie and isolated setting. The story, based on Albert Sánchez Piñol's novel, revolves around a lighthouse keeper and his encounter with strange creatures on a remote island. Lanzarote's dramatic scenery effectively enhances the film's atmospheric tension and themes of isolation.

In "Cold Skin," the monster is a creature known as a "humanoid amphibian," resembling a blend of fish and human features. These beings inhabit the isolated island where the film is set. They are depicted as violent and aggressive, primarily nocturnal, and driven by a primal instinct to protect their territory. The protagonist, a weather observer, encounters these creatures and grapples with themes of isolation, survival, and the nature of humanity as he navigates his relationship with them and his fellow human, a lighthouse keeper.
