The exact cause of his death Saturday was not reported.
Broadway veteran and brother of late author Mary McCarthy, Kevin McCarthy was an early member of New York's Actors Studio, and played hundreds of roles in films and on television throughout his career, The New York Times reported.
The Seattle native is perhaps best known for his work in the 1951 film "Death of a Salesman," the 1956 version of "Invasion of the Body Snatchers" and the 1961 movie "The Misfits."
Among the 18 Broadway productions in which he appeared were "Winged Victory," "Advise and Consent," "Three Sisters" and "Happy Birthday, Wanda June," the Times noted.
His last big-screen appearance was in the 2008 drama "Wesley."
McCarthy married actress Augusta Dabney in 1941. They had three children and divorced in 1961. He married lawyer Kate Crane in 1979 and they had two children. McCarthy's children and Crane survive him, the newspaper said.
