In director David Ayer’s wilderness survival thriller Heart of the Beast, Brad Pitt portrays retired Special Forces veteran James Belmont, fighting for his life across 58 miles of rugged Alaskan back-country after a plane crash. But as legendary animal coordinator Andrew Simpson (John Wick, Game of Thrones, Dog) revealed to Entertainment Weekly, Pitt had to share top billing with an unlikely rookie actor: a German Shepherd named Uber, who plays his combat-veteran dog, Odin.
In fact, on the film’s official daily call sheet, the canine star took the top spot: Odin was No. 1, and Brad Pitt was No. 2.

The Search: New Zealand Biosecurity & A Cold-Calling Marathon
With nearly 40 years of experience coordinating wolves and tactical canines, Simpson faced an immediate logistical hurdle when production selected a German Shepherd:
-
Biosecurity Deadlines: New Zealand—where the film was shot—enforces strict biosecurity protocols requiring at least 4.5 months of pre-entry preparation for foreign animals. With no time to import a trained dog from North America or Europe, Simpson had to find his lead locally.
-
The “Insurance Salesman” Hunt: Simpson scoured the country through cold calls to regional German Shepherd clubs, rescue shelters, and private breeders.
-
The Match: A local breeder sent a photo of Uber, a dog she had bred who returned to her care after his previous owner passed away. Simpson’s instant reaction:“Oh my God, that’s the Brad Pitt of dogs right there. I mean, he was just beautiful.”
-
Uber’s own puppies were also hired to serve as doubles, along with three specialty dogs handling puppy scenes, water rapids, and log crossings.
From Police Academy Dropout to Hollywood Star

Uber’s real-life backstory reads like a classic Hollywood discovery tale:
-
Too Friendly for the Badge: Uber originally entered police canine training, but washed out because he lacked predatory aggression: “He was just so kind that he failed the program. He didn’t have that aggressive streak in him,” Simpson noted.
-
Search & Rescue Experience: Following the police academy, he transitioned to search-and-rescue field work, desensitizing him to loud noises and chaotic environments before stepping onto a movie set.
-
VIP On-Set Treatment: As the undisputed star, Uber was backed by a dedicated 12-person entourage, including dedicated trainers, colorists, costume, makeup, American Humane monitors, and his own designated parking spot.
Behind the Scenes: Custom Prosthetics & Real Chemistry

| Production Challenge | How the Crew Solved It |
| Amputee Dog Portrayal | Odin is written as an amputee veteran dog. The team partnered with a New Zealand specialist who builds prosthetics for humans and dogs, crafting custom-fitted prosthetic sleeves tailored specifically to Uber and each double (including stunt and hero closeup models). |
| Physical Stunts with 3 Legs | Uber had to be trained to balance, run through swamps, swim, and jump out of a wrecked pontoon plane landing securely on three functioning legs. |
| Practical Filmmaking | Over 90% of the film was shot practically in real elements—real mud, freezing river water, dense forestry, and real timber—with minimal VFX assistance. |
| Bonding with Brad Pitt | Simpson praised Pitt’s willingness to get into the mud and water alongside the trainers: “When that dog looks at him and he looks at the dog, you can see that there’s a connection there… you can’t fake that.” |
