The actor Graham Greene died on September 1, 2025, in Stratford, Ontario, Canada, at the age of 73 (The New York Times obituary desk). His manager, Gerry Jordan, confirmed the death but did not disclose a specific cause.

USA TODAY national newspaper also reported a prolonged illness, quoting his representative Michael Greene. TMZ celebrity news outlet reported that Greene died in a Toronto hospital on Sunday afternoon with his wife Hilary Blackmore at his side, but said it was not given a cause of death.
