2001 - A Space Odyssey - 1968
A still from Stanley Kubrick’s 2001: A Space Odyssey (1968)

“Douglas Rain, who performed for 32 seasons with the Stratford Festival in Ontario but was perhaps most famous for one faceless movie role — the voice of the HAL 9000 computer in Stanley Kubrick’s landmark 1968 film, “2001: A Space Odyssey” — died on Sunday in St. Marys, Ontario. He was 90.”
