Josh Hartnett and Mackenzie Davis Face a Prehistoric Threat in the Official Trailer for Netflix Supernatural Thriller Series Below

Netflix has released the comprehensive official trailer and promotional posters for its upcoming six-part supernatural thriller series, Below, slated for a global streaming debut on October 8, 2026. Created and showrun by acclaimed screenwriter Jesse McKeown, the limited series combines elements of maritime horror, local mythology, and suspenseful mystery, set against the striking and isolated backdrop of coastal Newfoundland, Canada. The newly unveiled footage provides the most detailed look yet at the narrative’s core conflict, introducing audiences to an ancient, ice-bound entity that threatens a tight-knit fishing community.

Main Facts and Narrative Premise

At the center of Below is Calvin Penney, portrayed by Josh Hartnett. Penney is a steadfast, big-hearted, yet stubborn fisherman residing in a remote Newfoundland town. Still grappling with the psychological echoes of his father’s unresolved and mysterious death decades prior, Calvin finds his fragile sense of normalcy upended when an anomalous and massive iceberg drifts into the local harbor.

Contained within this glacial monolith is an unidentified, prehistoric sea creature. Once the ice begins to melt and unfreeze, the entity emerges, unleashing a wave of terror upon the coastal settlement. Calvin is thrust into a desperate struggle to protect his son, Wade, his extended family, and the broader community that defines his way of life. To confront the encroaching danger, Calvin forms an alliance with a visiting marine researcher, played by Mackenzie Davis, who brings scientific inquiry to the bizarre biological threat. Together, the duo must navigate local secrets, psychological trauma, and physical peril to stop the creature before the town is consumed.

Filming for Below took place entirely on location in St. John’s, Newfoundland, utilizing the rugged topography, dramatic coastlines, and authentic maritime atmosphere of the Canadian province to ground the supernatural narrative in a tangible reality.

This star-studded lineup has elevated anticipation for the project, positioning it as one of Netflix’s premier prestige television offerings for the autumn viewing season.

Chronology and Promotional Rollout

The marketing campaign for Below has unfolded steadily throughout 2026, building audience engagement through targeted promotional milestones:

  • Initial Teaser Release: Netflix dropped the first teaser trailer earlier in the year, offering brief glimpses of the remote Newfoundland setting, mounting atmospheric dread, and a fleeting look at Hartnett’s character reacting to the coastal crisis.
  • Trailer and Poster Debut (September 10, 2026): The streaming platform published the full-length official trailer alongside two theatrical-style character and thematic posters. This release provided substantial narrative context, confirming the iceberg-bound nature of the antagonist and the collaborative dynamic between Hartnett and Davis.
  • Scheduled Premiere Date (October 8, 2026): All six episodes of the limited series will become available simultaneously on Netflix, following the platform’s traditional binge-release model for select high-profile genre titles.

Industry Context and Market Implications

The arrival of Below aligns with a broader industry trend in 2026 featuring high-concept glacial and isolation-themed narratives. Industry analysts have noted thematic parallels with other high-profile cinematic and television releases this year, such as Alejandro Iñárritu’s upcoming film Digger, which also incorporates major glacial elements. This coincidence highlights a contemporary fascination with environmental isolation, prehistoric awakenings, and the vulnerability of human communities in the face of ancient natural forces.

For Netflix, Below represents a strategic investment in prestige limited series that leverage recognizable cinematic talent for television formats. By casting established film actors like Josh Hartnett and Mackenzie Davis in lead roles, the platform continues to bridge the gap between feature-film prestige and long-form streaming engagement. Furthermore, setting the series in a distinct Canadian location continues a growing industry movement toward utilizing authentic regional backdrops to enhance visual authenticity and regional storytelling depth.
