Whalefall follows a diver trapped inside a sperm whale

Whalefall follows Jay Gardiner, a young scuba diver swallowed by a sperm whale off the coast of Monterey.

Jay, played by Austin Abrams, had gone diving to search for remains of his late father, Mitt, played by Josh Brolin.

A squid draws Jay into the whale’s path, and he becomes trapped inside the animal.

The film is adapted from Daniel Kraus’ novel and directed by Brian Duffield.

Jay must find a way to survive inside the whale, facing dangerous conditions and using what he can find around him.

Memories of Mitt offer Jay practical lessons, but they also show the strain in their relationship.

The survival story is tied to Jay’s troubled bond with his father, which reviewers say sometimes interrupts the tense action.

The reviews discuss the film but do not say when it will be released or what comes next.
