Josh Hartnett Faces Deep-Sea Nightmares in Netflix's 'Below': Why This Gritty Aquatic Thriller Is Your Next Binge

Netflix Unleashes 'Below': Josh Hartnett Returns to Survival Horror

If you have been waiting for a maritime horror thriller that actually delivers nail-biting suspense instead of cheap jump scares, Netflix just dropped the ultimate October treat. Premiering globally on October 8, 2026, Below is a six-episode limited series created by Jesse McKeown (best known for writing duties on The Umbrella Academy). Starring Hollywood veteran Josh Hartnett—who continues his brilliant career renaissance following knockout turns in Christopher Nolan's Oppenheimer and M. Night Shyamalan's Trap—this eerie, atmospheric survival mystery takes the classic aquatic creature feature and gives it prestige-television depth.

Set against the unforgiving, fog-drenched shores of Newfoundland, Canada, Below follows grizzled local fisherman Nathan Hayes (played by Hartnett). When mysterious distress signals ripple through the North Atlantic and massive commercial vessels begin vanishing without a trace, Nathan and a tight-knit coastal community realize something ancient and carnivorous has risen from the ocean's abyssal depths. Rather than relying solely on giant tentacles, the series crafts a slow-burn psychological dread reminiscent of Mike Flanagan's Midnight Mass mixed with Peter Benchley's classic Jaws.

A Powerhouse Cast Navigates Cold Waters and Dark Secrets

What elevates Below beyond standard monster-movie fare is its exceptional ensemble cast. Joining Hartnett is sci-fi favorite Mackenzie Davis (Station Eleven, Blade Runner 2049), playing an unorthodox marine biologist who discovers that the creature's migratory patterns are tied to offshore corporate drilling. Meanwhile, Charlie Heaton (fresh off bidding farewell to Jonathan Byers in Stranger Things) delivers a grounded performance as Nathan's estranged younger brother, trapped between loyalty to his family and the town's desperate fight for economic survival.

Director Vincenzo Natali, the visionary filmmaker behind sci-fi cult classics like Cube and Splice, helms key episodes with visual flair. The production makes full use of freezing practical locations along the Canadian coastline, complementing sparse CGI with palpable claustrophobia whenever the camera dips below the freezing surf.
