Josh Hartnett has spent much of his career resisting the idea that an actor should stay inside one familiar box. In Netflix’s Below, that instinct pays off. His performance as Calvin Penney—a guarded Newfoundland fisherman, father, and man carrying old grief—puts him in a story that is as much about community and identity as it is about a creature lurking beneath the water.
Hartnett has not literally called Below “one of the most important roles of his career” in the interviews reviewed for this article. But his comments about choosing complex characters, his hands-on work as an executive producer, and the preparation he put into Calvin help explain why the role feels like a meaningful chapter in his ongoing career evolution.

Why Calvin Penney is different from a conventional hero
Calvin is not introduced as a flawless protector. He is stubborn, wounded, and deeply tied to a place that has shaped his family for generations. When a mysterious sea creature begins threatening Snook’s Arm, the danger forces him to confront not only what is happening offshore, but also the unresolved loss and fear he has carried for years.
That kind of contradiction is exactly the territory Hartnett has said he wants to explore. In an interview with Sharp Magazine, he described being drawn to characters with complicated motivations rather than straightforward heroism. Calvin’s protective instincts are real, but so are his blind spots. The tension between those qualities makes him feel like a person rather than a monster-movie action figure.
Hartnett went beyond learning lines
To portray a working fisherman convincingly, Hartnett immersed himself in the local culture and rhythms of Newfoundland. In Netflix Tudum’s interview, he explained that he listened to local radio and spent time learning about the region’s fishing history and the impact of industrial overfishing on coastal communities. He also got to know local fishermen and learned practical skills such as tying fishing nets.
The accent was another essential piece. The goal was not simply to imitate a sound; it was to make Calvin feel as though he belonged to the place. Netflix’s behind-the-scenes reporting notes that the cast worked with a dialect coach, while local performers helped ground the series in the region’s speech and customs.

The ocean gives the performance a personal scale
Hartnett has described the sea as both mysterious and humbling. Speaking to Netflix Tudum, he reflected on hearing stories from people who spend their lives on the water—accounts of things they could not easily explain—and on how much of the ocean remains unknown. That sense of wonder fits Below: its threat is frightening, but the ocean is not merely a backdrop for a creature feature. It is a living environment that people depend on and rarely control.
The production also gave Hartnett a new relationship with boating. He told Tudum that he spent time on a small boat watching humpback whales during the early weeks of filming. That experience offers a useful contrast to Calvin’s fear: the sea can be astonishing and beautiful, even when it is capable of sudden danger.

His role as executive producer matters, too
Calvin is the center of the story on screen, but Hartnett also served as an executive producer on the miniseries. In his interview with Sharp Magazine, he described that involvement as a welcome opportunity to contribute to casting, scripts, and post-production. For an actor, that can mean having a broader stake in how a character’s arc and the overall story reach the audience.
It does not mean every creative decision belonged to Hartnett, and it would be misleading to treat the series as a personal statement written entirely around him. Rather, his producing role gave him a chance to support the work beyond the hours spent performing. That additional responsibility fits an actor who has increasingly gravitated toward projects with unusual tones and layered characters.
Why the family story is as important as the monster
One of Below’s strongest choices is its focus on Calvin’s relationships, especially with his son Wade, played by Charlie Heaton. The creature creates the immediate crisis, but the emotional stakes come from a family trying to understand one another while the town’s future is in jeopardy. Hartnett has praised Heaton’s commitment to the character and described feeling a natural protectiveness toward his onscreen son.

That connection matters because Calvin’s courage is not measured only by whether he can face the creature. He must also decide what responsibility looks like when protecting his family conflicts with protecting the community and the place that shaped them.
Is Below a turning point for Josh Hartnett?
It is more accurate to call Below a continuation of Hartnett’s creative evolution than a sudden reinvention. Recent roles have increasingly allowed him to play people who are uncertain, morally complicated, or difficult to read at first glance. Calvin fits that pattern while giving him a distinctly physical, regional character whose life is bound to fishing, family, and a threatened coastline.
The series also gives Hartnett room to balance intimate scenes with large-scale genre storytelling. That combination is part of the appeal: the threat beneath the water may be extraordinary, but Calvin’s fear of losing his home and his family is recognizably human.
For viewers wondering whether Hartnett personally described this as one of his most important roles, the available interviews do not support that exact quotation. What they do show is an actor who values complexity, embraced the local setting, and took a more involved creative role. Those are strong reasons to see Below as an important fit for the performer he has become.
