Josh Hartnett Battles Sea Monsters in Netflix's Atmospheric Thriller 'Below'

The vast, dark expanse of the ocean has always held a certain terror, a place where the unknown can easily become the monstrous. Netflix’s new limited series, Below, taps directly into this primal fear, plunging viewers into the frigid waters off the coast of Newfoundland. Creator Jesse McKeown, known for his work on The Umbrella Academy, crafts a story that is as much about the secrets lurking beneath the waves as it is about the ones buried within a tight-knit community.

At the heart of Below is Josh Hartnett as a fisherman grappling with a haunted past, forced to confront a terrifying new reality when something ancient and deadly emerges from the deep. He’s joined by Charlie Heaton and Mackenzie Davis, adding further star power to this atmospheric thriller. The series, which premiered to critical acclaim at TIFF 2026, is a six-episode limited run, meaning every moment is tightly packed with suspense and narrative drive. McKeown and his team have clearly aimed for a show that is both visually stunning and narratively compelling, using the isolated setting to amplify the sense of dread and mystery.

Coastal Town Under Siege

The premise of Below is simple yet potent: a small seaside town finds itself terrorized by a mysterious sea creature. This isn't just a monster movie; it's a deep dive into how a community reacts when faced with an existential threat from the natural world, amplified by the secrets it desperately tries to keep hidden. The interplay between Hartnett’s haunted protagonist and the scientific perspective of a marine biologist, as they team up to protect their home, promises a dynamic central relationship. The critical reception so far highlights the show's success in building a supremely atmospheric and suspenseful experience, one that fans of creature features and character-driven mysteries will undoubtedly devour.

What Fans Can Expect

For fans of Jesse McKeown’s previous work, Below offers a darker, more intense tone. The series is designed for viewers who appreciate slow-burn tension, well-developed characters, and a healthy dose of the uncanny. The combination of a compelling cast, a creator with a proven track record in the genre space, and a terrifying premise makes Below a must-watch for anyone seeking a thrilling escape. The focus on uncovering dark secrets alongside battling a sea monster suggests a narrative that will keep viewers guessing until the very end, making it perfect for a weekend binge.

Release and Beyond

Below made its world premiere at TIFF 2026 on September 10th before its global debut on Netflix on October 8, 2026. With its limited series format, viewers can expect a self-contained, gripping story that offers a complete arc within its six episodes. Keep an eye on official Netflix channels for any post-release discussions or potential companion content, though the nature of a limited series suggests a focus on delivering a singular, impactful experience.
