Whalefall ★★★★

Released: 16 October 2026

Director: Brian Duffield

Starring: Austin Abrams, Josh Brolin

Claustrophobic genre films are a special type of unnerving: whether it’s being trapped in the creature-infested caves of The Descent or struggling to fit through tight catacombs in As Above, So Below, few things instil more fear than the suffocating terror of deadly enclosed spaces. None of them, however, are quite as organic as the literal belly of the beast in Whalefall, a film about an emotionally tormented diver swallowed whole by a giant sperm whale. It is the cinematic equivalent of a panic attack—and one that isn’t afraid of getting more than a little weird.

In the unlikely event that divers may need guidance in the art of whale extrication, Brian Duffield’s latest takes its premise extremely seriously. Thankfully, Whalefall is utterly devoid of irony: adapted from the deceptively complex novel of the same name by Daniel Kraus, this gooey adventure thriller doesn’t hold anything back, pushing the limits of its teen-friendly age rating. While attempting to find peace following the passing of his father, our unlikely survivor, Jay (Austin Abrams), is put through the wringer and forced to battle the odds within the depths of the whale’s digestive tract. Narratively, the film holds its cards close to its chest, revealing a depth below its man-vs-wild surface. Its genre origins, though, will give even the most seasoned divers a severe case of thalassophobia.

Duffield isn’t playing around: when our film’s ill-fated lead is almost turned into chum, this entire affair becomes a full-blown, nasty, horror-adjacent nightmare. If you thought that one scene in Jordan Peele’s Nope was pure sonic terror, Whalefall takes it up a notch and exposes its audience to the dreadfully squishy soundscape of the creature’s viscera. Even without the added sensory effects of a 4DX auditorium (which this film is seemingly tailor-made for), the experience is so inherently immersive that some squeamish audience members might want to skip a meal before entering the cinema.

Enough about the gloopy visuals, though. Kraus adapts his own material here, so the book’s sensitive core remains intact—just as it was on the page. Despite what the whole whale-swallowing endeavour might suggest, this is a rather poignant tale of childhood trauma and lifelong psychological pain. Not some trivial bubblegum trauma plot, either: by navigating Jay’s difficult relationship with his father, Kraus dismantles the traditional narratives around abusive parents and focuses on the knotty and often inscrutable nature of life beyond the abuse. Subject matter like that is always a challenge to translate to film without resorting to reductive trauma speak, so Duffield attempts it by doubling down on some of the book’s most surreal and evocative imagery—certainly a bold choice for a studio film of this calibre.

If nothing else, Whalefall proves that single-location thrillers have no size limit. It’s a miracle that the movie works as well as it does, even more so as an adaptation of such a singular novel. Austin Abrams serves as a fantastic anchor and makes the film’s emotional beats truly shine, while Josh Brolin’s conventionally rugged presence acts as a fittingly menacing stand-in for the titular whale. As far as high-concept genre films go, this might just be one of the strangest studio movies to grace your local multiplex in quite some time. Films like this are an endangered species.
