The trailer for “Whalefall” is better than we had any right to expect; it’s intense and anxiety-inducing. I guess I should have known better — the film’s premise demands tension. It’s a survival-horror story about a diver trapped inside a sperm whale with limited oxygen. Think “Buried” or “127 Hours,” but underwater.
It’s “Pinocchio,” “Moonfall,” and Jonah and the Whale, filtered through a horror lens.
Brian Duffield directs “Whalefall,” which led me to scroll through his filmography. He’s only helmed two features so far, “Spontaneous” (2020) and “No One Will Save You” (2023), both well-reviewed direct-to-streaming efforts. I’ve only seen the latter, which felt like a mid-tier version of “Hush” and “A Quiet Place.”
“Whalefall” stars Austin Abrams as Jay Gardiner, a diver searching the ocean for the remains of his late father, Mitt Gardiner, played by Josh Brolin. Soon after, he’s swallowed alive by the creature.
“Whalefall” is based on a well-regarded novel that alternates between the protagonist’s real-time struggle for survival inside the whale and flashbacks involving his late father. Duffield appears to be preserving that structure, and the book’s author, Daniel Kraus, even co-wrote the screenplay.
What I’m really curious about is whether the premise itself is biologically plausible. Can a sperm whale actually swallow a diver intact? It wouldn’t be a dealbreaker for me whatsoever, as the premise simply requires a suspension of disbelief, and the trailer’s tension and execution matter more than strict scientific accuracy. Still, it’s a question worth asking. So I googled it, and this is the answer I got:
Marine biologists generally say that a person being swallowed by a sperm whale is physically possible. The bigger issue is survival. A diver caught in the mouth of a sperm whale would likely face crushing forces, violent movement, a lack of breathable air, and potential injuries during the swallowing process. Even if the person reached the stomach intact, survival would be extremely unlikely. The whale’s digestive system, oxygen-poor environment, and the trauma involved make the premise highly speculative.
“Whalefall” hits theaters via 20th Century Studios on October 16, 2026.
