Brad Pitt took on an unexpected challenge for Heart of the Beast. The actor had to work as a dog trainer while filming the survival thriller with his canine co-star, Uber, who plays Odin. Directed by David Ayer, the film follows a former Special Forces officer stranded in the Alaskan wilderness.

In an interview with Entertainment Weekly, Ayer explained that the actor had to manage the dog without breaking character. He said, “We put Odin number one on the call sheet.” He revealed that Pitt “really considered himself as a supporting actor to the dog, but he’s also the dog trainer.”

Pitt therefore had to juggle multiple responsibilities during filming. According to Ayer, the actor had to “stay in character, create that presence, do his amazing craft as an actor” while also managing the dog. The director noted that Uber could suddenly become distracted, even by something as minor as a bee flying past him. He praised Pitt’s ability to handle everything, calling it “really unbelievable.”

Pitt also opened up to Entertainment Weekly about working with Uber. He revealed that the dog appears in around 95% of the movie and admitted that the experience was “challenging” because “dogs don’t necessarily know their lines.” Pitt said he kept treats with him and called Uber back whenever the dog wandered off during emotional scenes.

Here’s a video of Pitt and Uber on the sets of the movie:
