Book excerpt: Films have been a part of U.S. society for a century—a source of great enjoyment for the audience and of great profit to filmmakers. How does a mass entertainment medium deal with some of the great sources of dramatic real-life political and economic conflict—the Great Depression, the Cold War—in a way that attracts an audience without making it angry? How does an industry, which has from its beginnings been the subject of attacks from social, political and religious groups deal with political issues and conflicts? This book is an attempt to examine these questions; it is also an examination of some of the greatest and most interesting American films ever made—westerns, gangster films, comedies, war films, satires, and film biographies—to see what American films say about politics and politicians, and what these films, in turn, say about the audience for which they were produced.
