New ‘Whalefall’ Trailer Traps Austin Abrams Inside a Massive Sperm Whale

Survival thrillers have found renewed life in recent years by leaning into increasingly claustrophobic, high-concept premises, but few upcoming releases have committed to that formula quite as literally as Brian Duffield’s latest project. 20th Century Studios has been steadily building buzz around the film since its first teaser dropped earlier this summer, and a fresh trailer is now giving audiences their most detailed look yet at just how intense the story gets.

‘Whalefall‘ is based on Daniel Kraus’s 2023 novel of the same name, a book that quickly developed a reputation among readers for its emotionally charged, almost Jonah-like premise. Imagine Entertainment struck a pre-emptive film rights deal just before the novel’s publication, and 20th Century Studios later won a competitive bidding war for distribution rights, setting Duffield up to both direct and co-write the adaptation alongside Kraus himself.

The story follows Jay Gardiner, played by Austin Abrams, as he dives off the central coast of California searching for the remains of his late father, only to be swallowed whole by a massive eighty-foot, sixty-ton sperm whale. Trapped inside the animal’s belly with just one hour of oxygen remaining, Jay must draw on lessons his father taught him if he hopes to find a way out before time runs out.

Josh Brolin plays Jay’s father Mitt in flashback sequences, with Elisabeth Shue, John Ortiz, Jane Levy, and Emily Rudd rounding out the supporting cast. That emotional father-son dynamic sits at the heart of the film’s marketing, giving the survival premise a grounded, personal stake beyond just the visceral horror of its central setup.

Duffield has been candid about the creative challenge behind selling audiences on a premise that could easily read as absurd on paper. Speaking about the trailer’s decision to reveal the whale encounter within the film’s opening minutes, Duffield explained the reasoning behind that unusual structural choice, describing the sequence as too dramatic and unique not to showcase upfront rather than saving it as a late-film twist.

He’s also emphasized that the film avoids framing the whale as a villain. According to Duffield, the animal isn’t malicious or monstrous, simply an indifferent predator that happens to swallow Jay as an unintended byproduct of catching its actual prey, a choice meant to give the film a sense of beauty alongside its horror rather than leaning purely into creature-feature territory.

Much of that underwater tension was captured practically, with the film’s submerged sequences filmed inside a custom-built tank at the Radford Studio Center in Studio City, California. Duffield has described the shoot as an especially demanding technical challenge, one that required significant coordination to keep both safe and visually compelling given the scale of what the story demanded on screen.

‘Whalefall’ continues a pattern for Duffield, who previously directed the largely dialogue-free survival thriller ‘No One Will Save You.’ That track record of tackling high-concept, minimalist storytelling appears to have earned him enough trust from Kraus and the studio to take on adapting a novel many considered difficult to translate to screen given its intensely internal, physically constrained setting.

With the film’s October 16 release date now just weeks away, marketing has continued ramping up around its most striking hook: an ordinary diver forced to survive from inside one of the ocean’s largest predators. Given how much attention the trailer has already generated, ‘Whalefall’ looks positioned to be one of the fall season’s more distinctive theatrical offerings.
