Below Netflix Cast, Characters and Newfoundland Sea-Creature Mystery Explained

The Below Netflix cast is led by Josh Hartnett as Calvin Penney, a Newfoundland fisherman whose family and hometown are threatened by a mysterious sea creature. Mackenzie Davis plays visiting marine researcher Fonda Howander, while Charlie Heaton plays Calvin’s son Wade. Netflix has confirmed that the six-episode limited series premieres on October 8, 2026, with all six episodes available at once.

Below mixes creature-thriller suspense with a family drama about a community facing economic and cultural change. The story is set in the fictional Newfoundland town of Snooks Arm and was filmed on location in Newfoundland, giving the series a landscape and local identity that are central to the mystery rather than simply decorative scenery.

The show is especially notable for bringing together Hartnett, Mackenzie Davis and Stranger Things star Charlie Heaton in a story that begins with a frightening event at sea and quickly expands into a larger question: what is living in the water, what does it have to do with the town’s past, and how far will Calvin go to keep his family from being swallowed by the same history that has haunted him for years?

Below Netflix cast and characters

Netflix has confirmed the following principal cast. Several supporting characters have not yet received full official character descriptions, so this guide separates confirmed information from reasonable pre-release context instead of guessing at roles.

Josh Hartnett as Calvin Penney

Calvin Penney is the center of Below. Netflix describes him as a big-hearted but stubborn fisherman from Snooks Arm. He is also a single father of three who has spent years carrying the emotional weight of his father’s unexplained death. That old loss matters because the new threat does not arrive in an emotional vacuum. Calvin already sees his life as shaped by setbacks, bad luck and unfinished history.

The creature forces Calvin into a role he may not feel prepared for. He has to protect Wade and the rest of his family, keep a frightened community from falling apart, and work with an outsider whose scientific perspective may challenge the town’s assumptions. Hartnett has said the clarity of the scripts and the specificity of the Newfoundland setting immediately drew him to the project. He also serves as an executive producer.

Hartnett comes to the series after a strong run of recent genre work, including Oppenheimer and Trap, while many viewers will also know him from Black Hawk Down, Pearl Harbor and Penny Dreadful. Below gives him a different kind of genre lead: less polished hero, more bruised local father trying to keep his family together while something impossible rises out of familiar water.

Mackenzie Davis as Fonda Howander

Mackenzie Davis plays Fonda Howander, the visiting marine researcher who becomes Calvin’s key partner in understanding what is happening off the Newfoundland coast. Earlier Netflix material described Fonda as a marine biologist, while the newer official guide uses the broader term marine researcher. Either way, her role clearly brings scientific investigation into a story shaped by local myth, memory and fear.

That makes Fonda an important counterweight to Calvin. He knows the community, the coastline and the personal history around the mystery. She brings specialized knowledge and an outsider’s ability to ask questions that locals may have stopped asking. Netflix’s teaser also frames Calvin and Fonda as an investigative pair, with Davis describing their dynamic as something like two partners solving a mystery.

Davis is well suited to that combination of intimate drama and speculative suspense. Her credits include Station Eleven, Black Mirror, Blade Runner 2049, Terminator: Dark Fate and Speak No Evil.

Charlie Heaton as Wade Penney

Charlie Heaton plays Wade Penney, Calvin’s son and one of the characters most directly pulled into the danger. Netflix’s teaser says Wade begins showing disturbing symptoms after strange events spread through the village. The marketing deliberately avoids explaining what those symptoms mean, which makes Wade one of the clearest links between the family drama and the creature mystery.

For audiences who know Heaton primarily as Jonathan Byers in Stranger Things, the casting makes immediate sense. He has years of experience playing a character caught between family responsibility, supernatural danger and small-town secrets. Below is not a Stranger Things copy, though. Its setting, fishing-community culture and father-son dynamic give Wade’s storyline a different emotional foundation.

Willow Kean as Ruth Penney

Willow Kean plays Ruth Penney. Netflix includes Ruth among the main group surrounding Calvin, but has not yet published a detailed biography for her character. First-look material shows Ruth alongside Wade, Mary and Jay, reinforcing that the Penney family is the human core of the limited series. Until the episodes arrive, it is better to keep her exact relationships and individual plot points unspoiled rather than infer more than Netflix has confirmed.

Ruby Stokes as Mary Penney

Ruby Stokes plays Mary Penney. Stokes will be familiar to Netflix viewers from Lockwood & Co. and to period-drama audiences from Bridgerton. In Below, Mary is part of the Penney family group trying to survive both the physical danger and the pressure placed on the town. Promotional images show her closely connected with Jay, Noah and the other younger characters, but Netflix has intentionally kept the precise shape of her storyline under wraps.

Rohan Campbell as Jay Penney

Rohan Campbell plays Jay Penney. Campbell has appeared in Halloween Ends and The Monkey, giving him recent experience with horror and dark genre material. Jay is another member of the Penney family, and the early images suggest the younger generation will not simply wait for Calvin and Fonda to solve the problem. The family appears to be scattered across different parts of the town when the threat escalates, which can give the series multiple perspectives on the same crisis.

Kaleb Horn as Noah

Kaleb Horn plays Noah. Netflix has confirmed the name but has not released a detailed character biography. Promotional photos place Noah with Mary and Jay, indicating that he belongs to the younger group affected by the unfolding emergency. Because the series has only six episodes, even characters without long pre-release descriptions may become important quickly once the mystery begins connecting the town’s families and history.

Natasha Henstridge and Mary Walsh

Netflix’s official title page also lists Natasha Henstridge and Mary Walsh in the cast. The current Tudum character guide does not identify their roles, so any detailed description would be premature. Henstridge is strongly associated with science-fiction and thriller work, while Walsh is a major Newfoundland performer and comedian. Their presence broadens the ensemble beyond the Penney family and gives the production additional regional and genre experience.

What is Below about on Netflix?

Below begins in a remote coastal community where the sea is not only scenery. It is work, history, identity and danger. Calvin Penney makes his living as a fisherman in Snooks Arm while trying to hold together a family already marked by loss. Decades earlier, his father died under mysterious circumstances, and Calvin has never fully escaped the feeling that something about his life and his town is unresolved.

The present-day crisis begins when an unidentified sea creature starts terrorizing the community. Netflix’s trailer opens with an image designed to make the familiar feel impossible: a house being moved across the water is suddenly dragged beneath the surface. The event signals that whatever is happening is powerful enough to disrupt both the physical landscape and the assumptions the town has lived with for generations.

Calvin initially has the most personal reason to fight back. His children are in danger, Wade develops alarming symptoms, and the community’s way of life is already fragile. But the mystery grows beyond a simple creature hunt. Calvin teams with Fonda Howander, whose marine research may help explain what is happening beneath the water. Together they begin uncovering connections between the current attacks, the island’s buried secrets and the history Calvin has spent years trying to understand.

That structure is important. Netflix is selling Below as a thriller, but creator Jesse McKeown has repeatedly emphasized family and community. The monster creates urgency, while the town’s relationships create consequences. If the sea becomes unsafe, the people of Snooks Arm are not merely losing a place to swim. They are losing access to the work, routines and traditions that support the community.

What is the creature in Below?

Netflix has not revealed exactly what the creature is, and that is clearly intentional. The official synopsis calls it an unidentified sea creature, while the trailers focus on effects rather than a clean full-body reveal. Homes disappear, the water becomes dangerous, locals panic and Wade begins experiencing symptoms that suggest the threat may not operate like an ordinary animal attack.

The limited series also draws on local myth, which means the answer could involve folklore, biology, environmental change or some combination of the three. Until the episodes are released, claims about the creature’s species, origin or connection to Calvin’s father should be treated as theories rather than facts.

That mystery-first approach should appeal to viewers who like Netflix thrillers where the central danger is gradually defined. For another atmospheric Netflix crime-thriller ensemble, see our Blood Coast Netflix cast guide.

Why Calvin’s father matters to the mystery

Calvin’s father died mysteriously decades before the events of Below. Netflix has not explained the circumstances, but the fact is included in the official character setup for a reason. Calvin’s grief and belief that he has been marked by repeated tragedy shape how he responds when the new attacks begin.

The most likely narrative function is not simply to give Calvin a sad backstory. His father’s death provides a bridge between the town’s past and its present crisis. If the creature, the sea or the island’s hidden history played a role in that earlier death, Calvin may be investigating two mysteries at once: what is attacking Snooks Arm now, and what really happened to his father years ago.

Netflix has not confirmed that direct connection, so the article should not present it as solved. What is confirmed is that the series promises “buried secrets,” and Calvin’s unresolved family history is one of the clearest places those secrets could surface.

Why Newfoundland is central to Below

Below was filmed in Newfoundland, Canada, rather than using a generic coastal location to stand in for the province. Creator Jesse McKeown has said he had been visiting Newfoundland for years and wanted to build a story around its rugged isolation, humor, warmth and distinctive communities. The production also chose practical locations and real ocean work instead of relying entirely on green-screen environments.

That matters because the show’s central conflict is tied to a “vanishing way of life.” Fishing is not only Calvin’s occupation. It is part of the community’s relationship with the sea. A creature that makes the water dangerous threatens both survival and identity. The series can therefore use horror to explore a much more grounded fear: what happens when a place can no longer support the life people built around it?

Hartnett and Heaton also spent time learning about local speech and culture. Hartnett listened to Newfoundland radio discussions involving fishermen, while Heaton spent time in local communities and described being struck by the hospitality he encountered. Those details suggest the production wanted the setting to feel specific rather than interchangeable.

How many episodes are in Below?

Below has six episodes. Netflix describes it as a limited series, and all six episodes are scheduled to arrive on October 8, 2026. That makes it a binge release rather than a weekly rollout. Netflix has not publicly announced a second season, and the “limited series” label indicates the current story is designed as a contained event unless the company later changes its plans.

Is Below a horror series?

Netflix officially categorizes Below as a thriller and Canadian TV drama, but the premise clearly uses creature-horror and supernatural-mystery elements. The trailers feature an unseen force in the water, disappearances, panic, physical symptoms and a community under siege. Viewers should expect suspense and horror imagery, but the creators have also emphasized humor, family relationships and the social life of the town.

So the most accurate description before release is a creature thriller with family-drama, mystery and horror elements rather than a straightforward monster movie stretched across six episodes. Fans looking for other dark Netflix viewing can also browse our best sci-fi movies on Netflix guide.

Who created Below?

Below was created by Jesse McKeown, who also serves as showrunner and executive producer. His previous television credits include writing work on The Umbrella Academy and 19-2. The series is written by Karen Walton, Perry Chafe and Natty Zavitz. Jamie Childs, Helen Shaver and Stephen Dunn directed episodes.

Executive producers include McKeown, Jessica Rhoades through Pacesetter, Chris Hatcher, Josh Hartnett, Jamie Childs, Louise Sutton and Sharon Hall. The creative team’s background spans science fiction, character drama and dark genre television, which fits Below’s attempt to combine a large external threat with an intimate family story.

When does Below release on Netflix?

Below premieres globally on Netflix on October 8, 2026. Netflix’s official title page lists the series as TV-MA and identifies Josh Hartnett, Mackenzie Davis and Charlie Heaton as the top-billed stars. All six episodes are scheduled to release together.

Why Below could stand out among Netflix creature thrillers

The clearest difference is the setting. Many creature stories could be moved from one generic town to another without changing much. Below appears designed around Newfoundland specifically. The fishing economy, isolation, coastline, local humor and intergenerational relationships all shape what is at risk when the sea itself becomes threatening.

The second difference is the family structure. Calvin is not a lone scientist or action hero who happens to arrive where a monster appears. He is a father with a damaged family and a history connected to the place. The creature may drive the suspense, but Wade’s symptoms, Calvin’s father’s death and the strain inside the Penney family give the mystery personal stakes.

Finally, the six-episode format should allow the show to move quickly. There is enough space to investigate the town and its secrets, but not so much that the mystery needs to be stretched across a long season. For viewers who prefer compact Netflix mysteries, that limited-series structure may be one of the biggest attractions.
