On a gray January afternoon in 1955, a secretary at the Actors Studio on West 44th Street in Manhattan looked up to see a familiar face—too familiar, in fact, for that cramped little lobby. Marilyn Monroe, the most photographed woman in the world, had come alone to enroll in Lee Strasberg’s legendary acting workshop, the same crucible that had shaped Marlon Brando and James Dean. No press, no studio escort, no staged publicity shots—just Marilyn, signing herself in like any other student who wanted to get better at the work.
