Act One (1963) Moss Hart's best-selling autobiography provided the basis for this colorful backstage story. The film depicts Hart as a struggling young playwright in 1929, searching for a sympathetic impresario. Although his manuscript is rejected by a Broadway tycoon, a less prominent manager finally agrees to produce it - on the condition that Hart will get George S. Kaufman, a leading comedy writer, to collaborate on the final script. Hart sets out to convince Kaufman of his play's value, and so begins one of the most famous partnerships in the American theatre.
