Josh Hartnett Battles a Sea Monster in First Teaser for Netflix Thriller Series ‘Below’

Netflix has unveiled the first teaser for its upcoming thriller series ‘Below’, putting veteran actor Josh Hartnett at the front of a battle against a sea monster. The clip positions Hartnett as the protector of a small coastal community, suggesting high stakes for both the town and the streaming platform as it aims to capture viewers hungry for monster‑driven suspense. The teaser marks the series' first public visual, signaling a concrete marketing push.

The collective emphasis is on visual spectacle and the high‑concept premise that blends coastal folklore with modern thriller beats. None of the pieces provide details on the creature’s origin, episode count or release schedule, leaving the narrative scope ambiguous. Coverage is thin on whether the series will follow a single‑season arc or extend beyond the initial monster encounter.

What remains unknown includes the full cast lineup, the production timeline and the exact date when Netflix will add ‘Below’ to its slate.
