Joseph Estevez (born February 13, 1946 in Dayton, Ohio, USA) is an American actor. He is also the younger brother of Martin Sheen and the uncle of Charlie Sheen and Emilio Estevez, but to date has yet to achieve anywhere near the same level of popularity or critical respectability of his brother, or even his nephews. It's mainly due to starring in primarily low-budget B-movies of the Action and Horror genre. His initial claim to fame was being his brother Martin's voice double for the narration of Francis Ford Coppola's Apocalypse Now on days when Martin could not work.
