Brad Pitt has tackled Formula 1 racetracks and World War II battlefields, but his latest thriller pushed him to the brink in ways he never expected. Heart of the Beast, which hit theaters on September 25, has already become a crowd favorite, earning a Certified Fresh 84% from critics and a stellar 94% audience score on Rotten Tomatoes. The film has grossed $188 million worldwide, proving that Pitt's star power remains as potent as ever.
In the movie, Pitt plays James Belmont, a Special Forces veteran whose plane crashes into the Alaskan wilderness after he suffers a heart attack mid-flight. Stranded with his loyal service dog Odin, Belmont must rely on his training and instincts to survive the unforgiving elements. The story is grounded in realism, and that authenticity extends to the survival techniques shown on screen.
Now, as the film prepares for its digital release on November 10, Collider has an exclusive behind-the-scenes sneak peek featuring Pitt, director David Ayer, and bushcraft survivalist advisor Leif Swensen. Swensen, who has spent two decades training American pilots and military personnel in survival tactics, was brought in to ensure every detail—from building a fire to navigating with a map—was accurate.
"We got the best of the best," Ayer says in the clip, praising Swensen's expertise. The goal was to make the film a practical guide for anyone lost in the wild, while also selling Belmont's credibility as a seasoned soldier. Pitt recalls learning the nuances of creating a sustainable fire quickly, with Swensen emphasizing the importance of finding the driest wood possible.
For Pitt, the shoot was grueling in ways he hadn't anticipated. "Physically, I would absolutely say this is the hardest movie I've ever made," he told Collider's Joe Schmidt. The actor explained that the constant wetness and lack of recovery time added to the challenge, but he believes it ultimately made the film better. "You get in in the morning, you get wet, and you stay wet all day," he said. "There is a drudgery involved, but I believe in it because it informs the scene, it informs the characters, and it informs our movie in the end."
Heart of the Beast reunites Pitt with Ayer, who previously directed him in the 2014 war epic Fury. The film also marks the feature writing debut of Cameron Alexander. With most of the runtime focused on Pitt and the canine actors playing Odin, the movie relies heavily on their chemistry. J.K. Simmons and Anna Lambe add supporting star power, with Lambe recently appearing in Netflix's North of North.
As Heart of the Beast prepares to leave theaters, fans can catch it on digital platforms starting November 10. For those who missed the theatrical run, the behind-the-scenes look offers a fascinating glimpse into the making of one of Pitt's most demanding roles.
