Oscar-nominated actor Graham Greene has died at the age of 73, his agent has confirmed.
The star, who was best known for his role in Dances With Wolves, passed away following a "lengthy illness".
His manager, Gerry Jordan, confirmed the news to CBC News, as reported by the BBC, saying in a statement: "It is with deep sadness we announce the peaceful passing of award-winning legendary Canadian actor Graham Greene."
The outlet reports that the beloved actor died of natural causes following a "lengthy illness".
Greene's agent, Michael Greene (no relation), paid a touching tribute following the actor's death.
He told Deadline in a statement: "He was a great man of morals, ethics and character and will be eternally missed.
"You are finally free. Susan Smith is meeting you at the gates of heaven,” he added, referring to the actor’s longtime agent, who died in 2013.
Greene died on Monday, September 1 in a Toronto hospital following a lengthy illness, per the outlet.
The actor's breakthrough role was in Kevin Costner's 1990 directorial debut, Dances with Wolves, in which he played Kicking Bird (Ziŋtká Nagwáka).
The movie, which was an adaptation of the novel of the same name by Michael Blake, earned Greene an Academy Award nomination for Best Supporting Actor, among 12 nominations for the movie.
The film went on to win seven of the categories, including Best Picture, Best Director, and Best Writing, Screenplay Based on Material from Another Medium.
Greene reminisced on the project in 2017, telling Reader's Digest Canada, that the thing he loved most about the movie was his horse.
"He and I got on like a house on fire. On the last day I was shooting, this kid came up and told me it had been his - turns out he’d had to sell it.
"After filming, I went to the producers and said, 'Make sure this kid gets his horse back. Take it out of my salary if you have to," he recalled.
Greene's on-screen debut was in the 1979 Canadian drama series The Great Detective and he also later appeared in the 1983 film Running Brave, Deadline reports.
Though he made a successful career in the arts, Greene admitted to Readers Digest Canada that he had "stumbled into" the profession.
He explained: "I started out as a carpenter, a welder, a draftsman, a carpet layer, a roadie and an audio tech.
"I stumbled into acting and I thought, 'These people keep me in the shade, give me food and water, take me over to where I say what I’m supposed to say, then they take me back. Wow - this is the life of a dog.'"
Greene went on to appear in several blockbuster movies, including Maverick (1994), Die Hard With a Vengeance (1995), The Green Mile (1999), and The Twilight Saga: New Moon (2009), as well as The Twilight Saga: Breaking Dawn – Part 2 (2012).
He also had several television credits including Northern Exposure, Murder She Wrote, Lonesome Dove: The Series, Being Erica, Longmire, and Goliath.
Greene also won a Grammy in 2000 for best spoken word album for children for Listen to the Storyteller.
He is survived by his wife Hilary Blackmore, daughter Lilly Lazare-Greene and grandson Tarlo.
