Being swallowed alive by a sperm whale is the sort of intrusive thought most swimmers shake off before they reach the beach. Writer-director Brian Duffield turned it into a studio tentpole. Whalefall opens in theaters on October 16, 2026, released by 20th Century Studios.
The film adapts Daniel Kraus’ novel, which Duffield co-wrote with him. Austin Abrams plays Jay Gardiner, a diver working the central California coast in search of his dead father’s remains, who ends up inside a sperm whale with an hour of oxygen left. Josh Brolin plays the father, Mitt. Elisabeth Shue, John Ortiz, Jane Levy and Emily Rudd round out the cast.
Duffield’s pitch to 20th Century president Steve Asbell leaned on a famously long walk. “It’s Frodo’s journey, but it’s like 10 feet,” he told Polygon’s Matt Patches in an interview published September 11, 2026. The geography is tiny, the stakes are not. Duffield says the third act contains a set piece that escapes the stomach entirely and was deliberately kept out of the trailers.
The whale as co-star. Duffield’s stated benchmark was not Jaws but E.T. and King Kong, creatures audiences fall for despite being puppets and stop-motion armatures. Here the audience has to fall for one from the inside. He describes an 80 to 85 foot animal that never registers Jay’s existence at all, an innocent bystander in the middle of a squid hunt, and he pushed Abrams to treat it as a scene partner rather than a monster.
Built by Weta, finished by ILM. The practical sets came from Weta, with Industrial Light & Magic taking over a large share of the digital work. Duffield frames sound as the other half of the film’s architecture. He warned the sound team it would be the hardest job they had ever had, and says it was. Audiences should expect a near-constant heartbeat and the rush of blood through veins around Abrams, a reminder that the location is metabolizing.
The ratings line mattered too. Duffield says the production knew it had to land at PG-13, which meant calibrating exactly how revolting the stomach could get without the organ reading as sentient on its own. The studio’s own listing still shows the film as not yet rated.
It is a swing after No One Will Save You, Duffield’s alien-invasion piece that went straight to Hulu in 2023. This one was engineered for a big room. Duffield reaches for Stand by Me when describing the intent, a father-and-son story that reads differently at ten years old than it does at seventy.
Principal photography began June 9, 2025 in Los Angeles, with Monterey Peninsula work following on June 17, 2025. Aaron Morton shot it, Pietro Scalia cut it, and Joseph Trapanese scored it, for Imagine Entertainment and Jurassic Party Productions.
