He began acting while a college student, then became president of his school's Dramatic Club. In 1927 Tone began his professional stage career in stock, then soon made it to Broadway. He began appearing in films in 1932, going on to a busy screen career in which he was typecast as a debonair, tuxedo-wearing playboy or successful man-about-town. For his work in Mutiny on the Bounty (1935) he received a Best Actor Oscar nomination. In the early '50s he gave up films to return to the stage; after appearing in an off-Broadway prouction of Uncle Vanya he returned to film in the play's screen version (1958), which he co-produced, co-directed, and starred in. He appeared in a handful of films in the '60s; meanwhile, onstage he got good reviews for his performance in the New York revival of Strange Interlude. In the mid '60s he costarred in the TV series "Ben Casey." He was married four times; his wives included actresses Joan Crawford, Jean Wallace, Barbara Payton, and Dolores Dorn-Heft.
