 Citizen Kane was a rare film in that its principal roles were played by actors new to motion pictures. Ten were billed as Mercury Actors, members of the skilled repertory company assembled by Welles for the stage and radio performances of the Mercury Theatre, an independent theater company he founded with Houseman in 1937. "He loved to use the Mercury players," wrote biographer Charles Higham, "and consequently he launched several of them on movie careers."
