Netflix’s new thriller ‘Below’ stars Josh Hartnett as a fisherman battling a terrifying sea creature in a fight for survival beneath the ocean.
Netflix is taking viewers deep beneath the ocean with its latest thriller, “Below,” a new series starring A-list actor Josh Hartnett as a fisherman caught in a terrifying fight against a mysterious sea creature.
The streaming giant has released a chilling new trailer for the series, giving audiences their first major look at the underwater horror and the desperate battle at the center of the story. The series is scheduled to premiere on October 8, 2026.
Hartnett, best known for roles in films including “Black Hawk Down,” “Pearl Harbor” and “Oppenheimer,” takes on a dramatically different role in the Netflix production.
Josh Hartnett faces a terrifying threat
In “Below,” Hartnett plays a fisherman whose ordinary life at sea takes a horrifying turn when he encounters a mysterious creature lurking beneath the water.
The newly released footage emphasizes isolation, danger and the unknown as the character finds himself confronting a threat that appears to be far more powerful than anything he has encountered before.
Rather than relying solely on traditional jump scares, the trailer builds tension around the vastness of the ocean.
That setting gives “Below” an especially unsettling atmosphere. With miles of dark water surrounding the characters, escape is not as simple as reaching the nearest road or finding a safe building.
The ocean itself becomes part of the horror.
Netflix leans into creature-feature suspense
The trailer suggests that “Below” will combine survival drama with elements of a creature-feature thriller.
The central mystery revolves around the sea creature and what it is capable of, while Hartnett’s character appears increasingly desperate to survive.
Netflix has kept many details surrounding the series under wraps, allowing the trailer to establish the premise without revealing too much about the creature or the story’s biggest twists.
That approach could help make the series a strong addition to Netflix’s growing collection of genre programming.
The ocean becomes the ultimate horror setting
One of the most effective elements of the preview is its use of the ocean as a setting.
Unlike a traditional monster movie set in a city or remote wilderness, “Below” places its central character in an environment where humans are already at a natural disadvantage.
Visibility is limited. Help can be extremely far away. And beneath the surface, the unknown is virtually endless.
That combination creates an ideal setting for a survival thriller.
The trailer appears to capitalize on that fear, presenting Hartnett’s fisherman as someone forced to confront a creature that he may not fully understand.
Josh Hartnett takes on another major role
Hartnett’s casting adds another layer of interest to the project.
The actor has experienced a major career resurgence in recent years, appearing in Christopher Nolan’s Oscar-winning “Oppenheimer” and continuing to take on prominent film and television roles.
His performance in “Below” puts him at the center of a story that depends heavily on suspense and physical survival.
The role also gives Hartnett an opportunity to lead a genre series built around one of Hollywood’s most enduring fears: what might be hiding beneath the surface.
When does Netflix’s ‘Below’ premiere?
Netflix is scheduled to release “Below” on October 8, 2026.
The newly released trailer is expected to generate additional interest ahead of the premiere as viewers get their first extended glimpse at Hartnett’s character and the mysterious creature he must fight.
For fans of supernatural thrillers, ocean horror and creature features, the series could offer a particularly tense viewing experience.
The trailer leaves one major question unanswered: What exactly is lurking beneath the water?
Netflix appears to be counting on that mystery—and Josh Hartnett’s star power—to pull viewers into the deep.
