A silent-film actor who found even greater success with the advent of sound cinema, Ian Keith was never a major name, yet he appeared in numerous significant movies nonetheless. In 1930, he portrayed John Wilkes Booth in D.W. Griffith's first sound film, "Abraham Lincoln," and later worked with Cecil B. DeMille in the epics "The Sign of the Cross" and "Cleopatra." Keith also had supporting parts in swashbuckler adventures, notably "The Sea Hawk" and the 1948 version of "The Three Musketeers." Mostly appearing on television during the 1950s, Keith reunited with DeMille for "The Ten Commandments" in 1956, which proved to be the final film for both men.
