The names Harry Cohn, William Fox, Carl Laemmle, Louis B. Mayer, Jack and Harry Warner, and Adolph Zucker are giants in the history of contemporary Hollywood, outsiders who dared to invent their own vision of the American Dream.  Even to this day, the American values defined largely by the movies of these émigrés endure in American cinema and culture. Who these men were, how they came to dominate Hollywood, and what they gained and lost in the process is the exhilarating story of An Empire of Their Own.
