Monroe, then 24, had already played the girlfriend of a crooked lawyer in The Asphalt Jungle and was soon to be seen as "a graduate of the Copacabana school of dramatic art" in the Oscar-winning All About Eve. Still ahead: the subway-swept skirt in 1955's The Seven-Year Itch and her definitive comic performance, in 1959's Some Like It Hot, to say nothing of the inspiration she continues to provide Madonna and Gwen Stefani.
