When the news broke on September 1, 2025, that Graham Greene had passed away, it felt like the end of an era for both Hollywood and Canadian cinema. He wasn't just another actor. He was a pioneer. If you grew up watching Dances with Wolves, you knew him as Kicking Bird—the soulful, steady presence that basically anchored the entire movie. Honestly, seeing the headlines confirm his death at the age of 73 was a gut-punch for fans who had followed his 50-year career from small theater stages to the Academy Awards.
Graham Greene Cause of Death 2025: What We Know
So, what actually happened? When a beloved figure like Greene passes, people naturally want specifics. The official word from his representatives, including his longtime Canadian agent-manager Gerry Jordan and his U.S. agent Michael Greene, was that Graham Greene died of natural causes following a long illness. He passed away peacefully at a hospital in Stratford, Ontario.
There’s been a bit of confusion online—some reports initially said Toronto—but it was definitely Stratford, the place he had long called home. While the family hasn't released a specific medical diagnosis (and they have every right to that privacy), the term "long illness" usually points to a chronic condition the actor had been fighting behind the scenes for quite some time.
It’s kinda remarkable, actually. Despite being ill, he never really stopped working. He was a craftsman through and through. His agents mentioned he was "finally free," a phrase that suggests his final months might have been a physical struggle, though he handled it with the same quiet dignity he brought to his roles.

Graham Greene didn't even want to be an actor at first. That’s the wild part. He was a welder, a steelworker, and a roadie for rock bands. Basically, he was a guy who knew the value of a hard day's work before he ever stepped in front of a camera.
When Kevin Costner cast him in Dances with Wolves, Greene became the first Oneida actor nominated for an Oscar. He wasn't just "playing an Indian." He was portraying a human being with depth, humor, and a very specific moral compass. He once joked in an interview that the Oscar nomination changed his life with a simple "Yup." He wasn't one for flowery speeches or Hollywood ego.
- Breakthrough: Dances with Wolves (1990)
- Major Films: The Green Mile, Die Hard with a Vengeance, Maverick, Wind River.
- Recent Work: Reservation Dogs, The Last of Us, Tulsa King.
He had this incredible ability to make a scene better just by standing in it. Think about his role in The Green Mile. He didn't have the most lines, but you felt his presence. Same with his recent turn in Reservation Dogs. He was the elder statesman of Indigenous acting, and he took that responsibility seriously, even if he played it cool.

Greene’s death marks a massive loss for the Six Nations of the Grand River Reserve, where he was born. He lived a life that bridged two worlds—the high-glitz world of Los Angeles and the quiet, grounded life in Ontario with his wife of 35 years, Hilary Blackmore.
The tributes that poured in after September 1st weren't just from fans. They were from costars like Kevin Costner and younger Indigenous actors who saw him as the North Star for their own careers. He proved that you could be a First Nations actor and play a detective, a lawyer, or a grieving father—not just the stereotypical roles Hollywood had offered for decades.
What’s Next for Greene’s Fans?
Even though he's gone, we haven't seen the last of him on screen. Greene was a workhorse. Before he passed, he completed several projects that are slated for release throughout 2026.

If you want to honor his memory, the best thing you can do is revisit his filmography beyond the blockbusters. Look for his work in the Stratford Shakespeare Festival, or find old clips of him as Edgar Montrose on The Red Green Show. He had a comedic timing that was just as sharp as his dramatic weight.
Graham Greene wasn't just a "celebrity." He was a man of "morals, ethics, and character," as his agent put it. In an industry often accused of being shallow, he was the real deal. His cause of death might be listed as natural causes, but his life was anything but ordinary. He left the door open for every Indigenous actor who came after him, and that’s a legacy that isn't going anywhere.
Actionable Insight: To truly appreciate Greene's impact, watch his Oscar-nominated performance in Dances with Wolves followed by his guest appearance in Reservation Dogs. The evolution of his craft—and the way he paved the path for Indigenous storytelling—is the most fitting tribute to his life.
