Director Brian Duffield’s latest film, "Whalefall," offers a survival thriller that reimagines the narrative surrounding sperm whales, portraying the creature as a protector rather than a threat. The movie, adapted from Daniel Kraus’ 2023 novel, centers on a teenager named Jay, portrayed by Austin Abrams, who plunges into California’s Monastery Beach in search of his deceased father’s remains and is ultimately swallowed by a sperm whale. The story follows Jay's struggle to survive and escape from within the whale.
According to Duffield, the film’s approach is intentionally the "opposite of ‘Jaws’," aiming to evoke admiration and respect for whales rather than fear. The production sought input from whale experts, who responded positively, and Duffield expressed hope that audiences would be inspired to learn more about these marine mammals.
Josh Brolin, who plays Jay’s father, emphasized the emotional core of the film, highlighting themes of grief and complex father-son relationships. Brolin, deeply moved by the book’s conclusion, described crying after reading it and said he hopes the film encourages viewers to appreciate their families and the finite nature of time spent together.
The filmmakers created detailed whale interiors and exteriors on a large scale for authenticity, relying predominantly on computer-generated imagery to enhance the surroundings. Duffield noted that the production was among the most demanding of his career, pointing out that Abrams faced real physical risks while filming scenes set inside the whale.
Kraus was inspired to write the novel after encountering a viral video showing kayakers inadvertently inside a whale’s mouth. Further research, including consultations with experts, confirmed that under certain rare conditions, a person could be swallowed by a sperm whale. Duffield acknowledged that such an occurrence would depend on a highly unlikely combination of factors but added that sperm whales are known to consume prey smaller than giant squid, making the premise plausible within the story's fictional framework.
