Oscar-nominated actor Graham Greene died Monday in Stratford, Ont., at the age of 73, his manager has confirmed to CBC News.

"It is with deep sadness we announce the peaceful passing of award-winning legendary Canadian actor Graham Greene," Gerry Jordan said.

The Oneida actor from the Six Nations Reserve in Ontario was best known for film roles such as Kicking Bird, a Sioux medicine man, in 1990's Dances with Wolves, which earned him an Oscar nomination as best supporting actor. He was also in The Green Mile with Tom Hanks in 1999 and The Twilight Saga: New Moon in 2009.

On television, he had roles in Northern Exposure in the 1990s, and more recently as a guest star in Reservation Dogs and The Last of Us.

He told CBC Q's Tom Power earlier this year that he got his first acting opportunity when he was working as a roadie, and someone asked him if he'd ever considered acting.

Even though he said he knew nothing about the theatre — or even what a script looked like, he said — he gave it a try. And he loved it.

"I changed into the costume and they put me in the shade in a nice chair," he said. "They brought me food and water … and I thought, 'Jeez, I'm living the life of a dog! This is great. I don't have to carry anybody's amplifiers anymore. I don't have to do lights. I don't have to drive halfway across the country for nothing.'"

He went on to play dozens of roles on stage and on screen in a career that spanned almost five decades, eventually winning two Gemini Awards, a Canadian Screen Award for his role in Seeds, a Grammy Award (for best spoken word album for children for Listen to the Storyteller), and in 2025, the Governor General's Performing Arts Award for Lifetime Artistic Achievement.

"That was a major coup. I thought, 'Wow, why me?' " he said on Q. "It means a lot to be recognized in my own country."

Greene was also a member of the Order of Canada.
