Kenneth Turan brings to life the extraordinary partnership of Louis B. Mayer and Irving Thalberg and their role in creating the film industry as we know it "Sharply observant."-Farran Smith Nehme, Wall Street Journal One was a tough junkman's son, the other a cosseted mama's boy, but they dreamed the same mighty dream: that the right movies could make a profit and change both the culture and individual lives. Sharing a religion and an evangelical zeal for film, Louis B. Mayer (1884-1957) and Irving Thalberg (1899-1936) were unlikely partners in one of the most significant collaborations in movie history. Over the course of their decade-long relationship, as key players at Metro-Goldwyn-Mayer and major players in Hollywood, they joined forces in redefining and mastering the template for the film industry. Mayer, older by more than a dozen years, was the business-minded face of the studio, while Thalberg worked closely with the creative corps, especially writers; together they rarely set a foot wrong. And while Mayer initially viewed Thalberg as the son he never had, the two would go from passionate friends to near enemies before Thalberg's shocking death at the age of thirty-seven. In the first joint biography of the two men in fifty years, film critic Kenneth Turan traces their fraught relationship while examining the complicated history of Jewish identity in Hollywood.
