Extras, bit players, and stand-ins have been a part of the film industry almost from its conception. On a personal and a professional level, their stories are told in Hollywood Unknowns, the first history devoted to extras from the silent era through the present. Hollywood Unknowns discusses the relationship of the extra to the star, the lowly position in which extras were held, the poor working conditions and wages, and the sexual exploitation of many of the hardworking women striving for a place in Hollywood society.
