Anthony was born on May 20, 1936 in Long Beach, CA. Early on he disdained the "surfer" mentality of his California boyhood friends, Anthony chose to head to New York to become an actor. He studied with Stella Adler and worked off-Broadway before achieving success in the mid-'60s. He made his film debut in 1967's Will Penny, after which he settled into a series of sharkish, saturnine villainous portrayals. An adherent of EST training, Anthony preferred to work with people who allowed him "space" to develop a characterization; one such person was David Janssen, with whom Anthony appeared on the mid-'70s TV series Harry O (in which he won an Emmy award for his portrayal of Lieutenant Trench). Active on-stage and in films and television into the 1990s, Anthony has contributed some unforgettable acting moments to the big screen, notably as the shadow-enshrouded leper in 1971's Papillon and the "blowed up real good" secondary villain in the 1989 James Bond opus License to Kill.
Anthony currently focuses on his stage work, and resides with his wife in CA.
