James Shapiro, a professor of English at Columbia University in New York, starts his new book with an epigraph listing two dictionary definitions of ‘playbook’: ‘[a] book containing the scripts of dramatic plays’, but also a ‘set of tactics frequently employed by one engaged in a competitive activity’. The Playbook turns on bringing these two definitions together. It argues that the Federal Theatre Project that developed in the United States between 1935 and 1939, as part of Franklin D. Roosevelt’s New Deal program, was effectively scuppered by the political machinations of ambitious Texas congressman Martin Dies. In 1938, the wily Dies succeeded in setting up the House Un-American Activities Committee (HUAC), with himself at its head. HUAC became notorious during the Cold War, under the direction of Joseph McCarthy, for its persecution of political dissenters. Shapiro’s thesis is that its nefarious influence began earlier, with the democratic principles he regards as inherent in theatre being peremptorily shut down by Dies’s political opportunism. Shapiro presents this conflict as a forerunner of more recent American culture wars driven by Pat Buchanan in the early 1990s through to Donald Trump in the present day.
