Brian Duffield has a talent for high-concept pitches — babysitters who are devil worshippers, spontaneous human combustion at high school, home invasion but aliens — that land with more punch in a logline than on a screen. Whalefall, his adaptation of Daniel Kraus's Pulitzer-winning novel, is his purest expression of that gap. A man trapped inside a living sperm whale is the kind of premise that makes you immediately curious about how anyone survives it. The answer, unfortunately, is: barely, and not in the ways that matter. Austin Abrams, fresh from Resident Evil and carrying real goodwill from Euphoria, is in every scene. He screams, writhes, burns in stomach acid, wrestles with a simultaneously swallowed giant squid, and looks believably terrified throughout. Duffield makes the whale's interior feel genuinely alien — the decision to treat the beast's body as an extraterrestrial landscape is the film's best idea. The problem is that it is also a severely limiting one. There are only so many set pieces a single-location survival film can generate before the visceral becomes repetitive, and Whalefall reaches that ceiling well before the halfway mark. Duffield compounds the setting's inherent constraints with a series of choices that close off the film's remaining options. No voiceover, despite the source novel's access to interiority. Breathing apparatus that muffles whatever dialogue Abrams might otherwise deliver. These are defensible instincts — he wants authenticity over explanation — but they leave the film with no mechanism for conveying what Jay is actually thinking or feeling beyond physical reaction. In a single-character survival film, that's not a stylistic choice; it's a structural wound. The attempted remedy is a series of father-son flashbacks. Josh Brolin plays Jay's recently deceased father, who chose to drown himself rather than die slowly of mesothelioma, and whose body Jay is diving to recover for reasons the film never quite pins down. The flashbacks are supposed to give Jay's underwater ordeal emotional stakes — this isn't just survival, it's proof of something to a difficult man. But the father-son material is written and staged at a CW network register: hackneyed advice ('Survivors survive!'), gruff withholding, a hallucinatory final chat in which the dead father's big questions include whether Jay ever wanted a dog. It lands as unintentional comedy. Elisabeth Shue, as Jay's mother, is present long enough to remind you of how much better the film could have been with her more centrally involved. The film's influences, which Duffield has shared publicly and which include Brokeback Mountain, JFK, A Little Prayer, and West Side Story, are a genuinely baffling list that fails to leave any detectable fingerprint on the finished product. What you actually get is closer to Underwater with a single character, or a feature-length version of the whale scene in Finding Nemo played straight and stretched to nearly twice its natural length. At 85 minutes, this could have been a lean, efficient genre exercise. At 106, it becomes an endurance test of a different kind than intended — not the hero's survival, but the audience's. The film does have real assets. Its practical-effects work and production design give it a studio sheen that's genuinely rarer than it used to be. The squid mayhem is effectively gross. Abrams is an actor worth following — his likeability survives the material, which is a meaningful testament to his presence. But the film around him keeps switching channels between creature-feature survival horror and family-drama therapy session, and neither mode earns the other. You want to grab the remote.
