The Superdeep (2020)

The Superdeep (2020) is a Russian sci-fi horror film directed by Arseny Syuhin. Inspired by the real-life Kola Superdeep Borehole—a Soviet drilling project that went over 12 kilometers (7.5 miles) underground—the film takes a terrifying approach to the mysteries of what might be lurking beneath the Earth’s surface.
The story follows Dr. Anya Fedorova (Milena Radulovic), an epidemiologist with a traumatic past, who is sent on a mission to investigate strange occurrences at the Kola Superdeep research facility. Reports from the station indicate that the team of scientists and researchers stationed there have been infected by an unknown and highly contagious disease. The Soviet government fears that the discovery could be a threat to humanity and tasks Anya and a small group of soldiers with assessing the situation and containing any possible outbreak.
Upon arrival, the team quickly realizes that something has gone terribly wrong. The underground facility is in a state of chaos, with many of the researchers either dead or suffering from horrific mutations. They soon uncover a terrifying truth: the infection is not caused by a conventional virus but by a mysterious organic entity that spreads like a fungus, consuming and merging with its hosts. The deeper Anya and her team go, the more they encounter grotesque, inhuman creatures—former scientists who have become part of the living mass of the underground nightmare.
As Anya struggles to survive and uncover the origin of the infection, she faces both external horrors and inner demons. The film builds an atmosphere of paranoia and dread, heavily influenced by classic horror films like The Thing (1982) and The Descent (2005). The claustrophobic setting, eerie sound design, and disturbing visuals heighten the suspense, making the underground base feel like a tomb where escape seems impossible.
Ultimately, The Superdeep explores themes of scientific hubris, the dangers of meddling with the unknown, and the terrifying possibility that some secrets are better left buried. While the film received mixed reviews due to its pacing and execution, it remains a visually striking and unsettling addition to the body horror and sci-fi horror genres.
