John Holland Cazale (; August 12, 1935 – March 13, 1978) was an American actor. He appeared in five films over seven years: ''The Godfather'' (1972), ''The Conversation'' (1974), ''The Godfather Part II'' (1974), ''Dog Day Afternoon'' (1975), and ''The Deer Hunter'' (1978), each of which was nominated as Best Picture at their respective Academy Awards. Cazale started as a theater actor in New York City, ranging from regional, to off-Broadway, to Broadway acting alongside Al Pacino, Meryl Streep, and Sam Waterston. Cazale soon became one of Hollywood's premier character actors, starting with his role as the doomed, weak-minded Fredo Corleone opposite longtime friend Al Pacino in Francis Ford Coppola's film ''The Godfather'' and its 1974 sequel, as well as Sidney Lumet's ''Dog Day Afternoon''. In 1977, Cazale was diagnosed with lung cancer, but he chose to complete his role in ''The Deer Hunter''. He died shortly after, in New York City on March 13, 1978.
