Imagine being swallowed alive by a giant sperm whale, with no way to call for help and a steadily diminishing chance of making it back to the surface. Whalefall takes this unsettling premise and turns it into an underwater survival thriller. Brian Duffield deserves credit for attempting something different in a genre overcrowded with familiar tales of shark attacks.
Based on Daniel Kraus’ novel of the same name, Whalefall follows Jay Gardiner (Austin Abrams), a young diver whose search for his father’s remains takes a terrifying turn when he is swallowed by a sperm whale. What follows is a desperate race against time, as Jay must navigate the creature’s enormous body, contend with its hostile internal environment and find a way out before he runs out of air.
On paper, this is an exciting premise that practically sells itself. The challenge, however, lies in sustaining the tension over a feature-length runtime without stretching the limits of plausibility. Whalefall manages both often enough to remain compelling, but its uneven execution prevents it from becoming the gripping survival drama it could have been.
Abrams is the film’s biggest asset. As Jay, he spends much of the runtime alone, communicating his desperation through physical performance, muffled speech and expressions of mounting panic. With his character unable to breathe freely or engage in conventional conversations, the actor has to do much of the emotional heavy lifting without the usual tools of dialogue-driven drama. He makes Jay’s predicament frightening.
Jay is not an inexperienced adventurer who finds himself hopelessly out of his depth. Diving has been a part of his life since childhood, taught to him by his father, Mitt (Josh Brolin). His knowledge gives him a fighting chance, but it also brings him face to face with the memories of a relationship marked by unresolved conflict.
The circumstances surrounding Mitt’s death give the story its emotional foundation. A difficult, domineering man whose failing health had made his final days increasingly painful, he chose to sink to the ocean floor rather than wait for illness to claim him. Jay, still struggling with the weight of their fractured relationship, sets out to recover his father’s body.
Duffield uses flashbacks to explore this complicated bond, allowing Mitt’s lessons in diving to become part of Jay’s struggle for survival. Techniques once taught by an overbearing father acquire a different significance when his son must depend on them to stay alive.
Brolin brings considerable intensity to Mitt, capturing the frustration of a man confronting his own mortality and the damage his temperament has inflicted on his family.
Duffield, who also wrote the screenplay, creates an underwater world that feels both magnificent and terrifying. The whale’s body becomes an alien landscape, an environment in which familiar rules no longer apply and every movement could bring another danger.
The moments of body horror are also immersive. Corrosive stomach fluids, the threat of suffocation and the chaos created by other creatures swallowed alongside Jay give the film a distinctly unpleasant edge.
Yet the same premise that gives Whalefall its distinctive identity also becomes its biggest limitation. There are only so many obstacles Jay can encounter inside a whale before the sequence of problems begins to feel repetitive. The film repeatedly shifts between the immediate mechanics of survival and flashbacks to his troubled family life, and the transition does not always work.
As a survival thriller, the film could have benefited from a tighter runtime and a more concentrated approach. As exploration of a fractured father-son bond, it needed greater subtlety in places.
The final act is where the film’s weaknesses become most apparent. After spending much of its runtime establishing a reasonably grounded set of survival challenges, Whalefall takes a turn that stretches credibility beyond what its already far-fetched premise can comfortably sustain.
