Actor Michael O'Keefe was educated at NYU and trained for a theatrical career at AADA. O'Keefe made his first off-Broadway appearance in 1974's Killdeer, his Broadway debut in Fifth of July, and in 1975 made his TV bow in the small-screen remake of Friendly Persuasion. Within a year of his 1978 film debut, he was Oscar-nominated for his portrayal of Ben Meechum (author Pat Conroy's alter ego) in The Great Santini (1979). He followed that up by starring opposite comedy heavyweights Chevy Chase and Rodney Dangerfield as the caddy Danny Noonan in Caddyshack.
While his subsequent stage credits were consistently praiseworthy -- he won a 1982 Theatre World Award for Mass Appeal, and was a co-founder of the Collanade Theatre Lab -- his screen efforts of the 1980s alternated between brilliant (Ironweed) and lamentable (The Slugger's Wife). On television, O'Keefe was briefly seen as Jackie's (Laurie Metcalf) husband Fred on Roseanne (1988), gonzo attorney Simon MacHeath in Against the Law (1990), suburbanite Ron Steffey in Middle Ages (1992), and also as basketball coach/househusband Kevin Hunter in Life's Work (1996).
O'Keefe continued to work steadily in film and television, in movies like The Hot Chick (2002) and Michael Clayton (2007) and with guest appearances on shows like The West Wing, House, The Closer, Criminal Minds, and Brothers & Sisters. In 2014, he had a recurring role on Homeland's fourth season.
