Heart of the Beast

Plot

Retired Special Forces Command Sergeant Major James Belmont and his combat dog Odin, both suffering from PTSD and nightmares, land their Cessna Skywagon on a remote Alaskan lake and make camp for the night. While exploring the surrounding forest, Belmont cautiously encounters Watkins, an outgoing stranger. Watkins sets up camp next to Belmont and they talk into the night. The next morning, Watkins departs and leaves Belmont a book in exchange for a beer he had taken from the camp overnight, highlighting a particular passage.

Belmont and Odin pack up and depart by plane, but Belmont suffers a heart attack mid-flight and crashes into a body of water. Odin is ejected from the plane during the crash. Belmont finds Odin nearby, weak but alive, and returns to the wreckage to salvage his gear. When Odin's condition improves, the pair set out on foot to hike back to civilization which is about 58 miles away, according to Belmont's calculations.

During their trek, they are confronted by a grizzly bear, which Odin faces down until it retreats. They later reach a precarious wooden bridge spanning a valley. Belmont slips and swings Odin to safety before falling into the rapids below, wedging his arm between rocks and breaking it. Odin finds Belmont in the river and drags him to shore, then helps him reset the broken bone.

In the distance, they spot a pack of gray wolves attacking a moose calf, so they prudently retreat. That night, the pair are subsequently ambushed by the wolves. Belmont fights them off using a spear and a knife, while Odin attacks them in self defense; Belmont eventually kills all the wolves (except one who fled), but is fatally bitten in the stomach in the process. The next day, Belmont and Odin then wade through a swamp, where Belmont gets caught, also fatally, under submerged branches but manages to free himself by diving underwater.

As his condition deteriorates, Belmont repeatedly stumbles until he reaches the top of a hill. Weakened and unable to continue, he rests and points to a nearby road, instructing Odin to run to it. He also writes a letter recording his final wishes for Odin, along with an account of their ordeal, and leaving all of his money for whomever takes Odin in, and subsequently dies. Odin leaves his side and reaches the road, where a young woman named Amber finds and takes him in.

Production

In March 2024, David Ayer signed on as director with a script by Cameron Alexander that was featured on the 2017 Black List of the year's 'most liked' unproduced screenplays; Alexander served as an executive producer. Damien Chazelle and Olivia Hamilton produced the film through their label Wild Chickens Productions, with Paramount Pictures distributing as part of a first look deal between the companies, and Ayer and Chris Long serve as producers through Cedar Park Entertainment. In January 2025, Brad Pitt was announced to be starring in the project, also producing under his Plan B Entertainment banner. Temple Hill Entertainment also joined the project, with Ayer now producing under Crave Films. In February, J. K. Simmons joined the cast, with Anna Lambe joining a month later.

Principal photography began on March 3, 2025, in Queenstown, New Zealand, and wrapped on May 15.

Jared Michael Fry was hired to compose the score for the film, marking his third collaboration with Ayer following The Beekeeper (2024) and A Working Man (2025).

The watch Pitt wears in the movie is a Rolex Submariner, but the interesting fact is that the strap was spotted by the Director David Ayer on the wrist of a friend. As a result, the creator of the strap, Matt Jackson of UK company NDC Straps was approached to supply four pieces for the production. The strap was an old model and no longer made, so Jackson had to find four examples in old stock and send them to the producers.
