The profound cultural and political changes of the 1960s brought the United States closer to social revolution than at any other time in the twentieth century. At the same time, American cinema underwent radical change as well. The studio system crumbled, and the Production Code was replaced by a new ratings system. Among the challenges faced by the film industry was the dawning shift in theatrical exhibition from urban centers to suburban multiplexes, an increase in runaway productions, the rise of independent producers, and competition from both television and foreign art films. Hollywood movies became more cynical, violent, and sexually explicit, reflecting the changing values of the time. In ten original essays, American Cinema of the 1960s examines a range of films that characterized the decade, including Hollywood movies, documentaries, and independent and experimental films.
