Whalefall Opens: A Diver, A Whale and One Hour of Air
A diver with one hour of air is trapped inside a whale. That is the tight set-up of Whalefall, which opened exclusively in theatres on 16 October 2026, from 20th Century Studios and Imagine Entertainment 20th Century Studios.
The film is directed by Brian Duffield and based on Daniel Kraus' novel Deadline. It follows Jay Gardiner, played by Austin Abrams, who dives off the central Coast of California to look for his father's remains. He is then swallowed by a massive sperm whale after a tangle with a squid.
Jay has only one hour of oxygen left inside the whale's belly. His father, Mitt Gardiner, played by Josh Brolin, is already dead when the story starts. Mitt died by suicide by drowning in the Pacific Ocean after a mesothelioma diagnosis, a form of cancer linked to asbestos Deadline.
The cast also includes Elisabeth Shue, John Ortiz, Jane Levy and Emily Rudd. The film is rated PG-13 and credits a screenplay by Duffield and Kraus based on the book 20th Century Studios.
Grief sits at the centre of the survival story. Duffield has summed it up with the line that men would rather get swallowed by a sperm whale than go to therapy. He said becoming a father helped him connect to that theme, as his son was one or two years old while he worked on the film.
The production mixed large physical sets with digital effects. Deadline visited the set at Radford Studios in Los Angeles in September during an early tank scene. Multiple stomach models were built by Weta Workshop in New Zealand, while the head, throat, oesophagus and larynx were built in California because they were too big to ship to set on time Deadline.
That whale head was huge. It stood 12 feet tall and stretched 18 feet long, and was manufactured by StudioArt & Technology. Visual effects supervisor Guillaume Rocheron, who previously worked on Jordan Peele's Nope, rigged LED lighting inside the stomach so it could be rendered as bioluminescence, the natural glow made by living organisms.
What makes this stand out for film fans is the scale of the build. The film was shot in California, and the team moved between water tanks, practical whale parts and computer imagery to keep Abrams sealed inside the animal for long stretches.
