Netflix Drops Trailer for Below, a Six-Episode Sea-Creature Thriller Starring Josh Hartnett

# What the trailer shows

Netflix has released the full trailer for Below, its six-episode limited series that mixes local mythology, suspense, and moments of dark humor. The footage centers on Josh Hartnett's character, Calvin Penney, a stubborn Newfoundland fisherman whose life and community are threatened when an unidentified sea creature begins terrorizing the town.

# Who's in the cast and creative team

• Josh Hartnett plays Calvin Penney, a big-hearted yet stubborn fisherman haunted by his father's unresolved death decades earlier.
• Charlie Heaton appears as Wade, Calvin's son.
• Mackenzie Davis plays Fonda Howander, a visiting marine researcher who teams up with Calvin to confront the threat.
• Supporting cast includes Ruby Stokes, Kaleb Horn, Rohan Campbell, and Willow Kean.

The series was created by Jesse McKeown. Executive producers include Jessica Rhoades (Pacesetter), Chris Hatcher, Josh Hartnett, Jamie Childs, Louise Sutton, and Sharon Hall. Writers credited on the series include Karen Walton, Perry Chafe, and Natty Zavitz. Directors on the project include Jamie Childs, Helen Shaver, and Stephen Dunn.

# Premise in plain terms

Calvin Penney is trying to protect his family, his son, and a town that's already running out of fish and opportunity. When a creature—apparently freed or released following environmental changes—begins attacking the community, Calvin teams with marine researcher Fonda Howander to stop it and uncover buried secrets tied to his family history.

The show ties the creature plot to deeper unresolved events, specifically the mysterious death of Calvin's father, which the series threads through present-day events.

# Release and festival details

Below premiered at the Toronto Film Festival on September 10, 2026. Netflix will release the entire six-episode series globally on October 8, 2026.

# What to expect watching the trailer

• Tense, coastal atmosphere and small-town stakes rather than heavy creature reveals.
• Focus on character relationships—father and son, the outsider scientist, and local community members.
• A blend of genres: local folklore elements, suspense, and touches of humor.

# Context for viewers and fans

Hartnett's casting points to a lead who brings both genre experience and dramatic weight. Mackenzie Davis and Charlie Heaton add recognizable supporting profiles. The creative team includes writers and directors with television experience, and the series' festival premiere suggests Netflix positioned it for visibility ahead of its streaming launch.

If you prefer creature stories that preserve mystery and emphasize community consequences, the trailer indicates Below will follow that approach, keeping the creature largely offscreen while showing the fallout it causes.
