Janet Montgomery (New Amsterdam, Salem, Black Swan) is starring in the new body horror, Symbiosis, per Deadline.

Symbiosis is set in a remote research station in Scotland and follows, “a husband-and-wife team are working over Christmas as the only two people who can save humanity from an alien parasite — tiny tapeworm creatures which have invaded the bodies of the human race. Isolated and suffocating under the weight of their circumstances, the fault lines of the married couple’s relationship are exposed. Additional casting is being finalized.”

The film is directed by Mark Heller (The Passage) and is written by Stephen James Thompson.

Director Mark Heller tells Deadline: “Symbiosis is a psychological horror film that blends an intensely human story with an unsettling sci-fi premise. At its core, it explores the fragility of survival, both in our relationships and as a species, and how, ultimately, the true question of symbiosis may not just lie with otherworldly entities, but in our own ability to coexist.

“Using cutting edge techniques, I intend to create a feeling of intense claustrophobia in a stripped back setting where performance, atmosphere and tension will take centre stage. Symbiosis will combine the starkness of a classic and visceral body horror with the intimacy and raw emotion of chamber drama. As a story of isolation, emotional truth, fear and hope, this is a film that dares to ask difficult questions. From our fear of the unknown to the deeply unsettling possibility that what we consider to be parasitic may, in fact, be something far more complex and necessary to our survival.”
