An illustrated, scholarly investigation of the genesis and development of American film, prepared with the support of the National Endowment for the Humanities. "Grand Design", the fifth in the series, studies the advent of colour, big musicals, the studio system and the beginning of institutionalized censorship which made the thirties the defining decade for Hollywood, the decade that ended with "The Greatest Year in Motion Pictures" - the year of "Gone With the Wind", "The Wizard of Oz", "Mr Smith Goes to Washington" and other classics. This reference series should become the standard source in every library.
