In 1948 director Elia Kazan started work on a strange new play by Tennessee Williams, and in 1953 Camino Real opened and quickly closed on Broadway. How did they create this astonishing work? How did Kazan's 1952 testimony before the House Un-American Activities Committee and its traumatic aftermath affect the creative process? Was Camino indeed a flop, or was it actually an important success? Obie Award-Winning Target Margin Theater's company-created piece The Really Big Once is the story of these two giants and how they changed American culture.
