In 1936 Margaret Mitchell, a young writer from Atlanta, published her first novel: "Gone With the Wind." The American Civil War epic quickly became a best-seller and earned Mitchell the Pulitzer Prize. David O. Selznick and MGM began working on screen adaptation, the filming of which would become its own epic involving multiple directors, an enormous budget, and even secret auditions as half of Hollywood vied for a part. But it all paid off: the film smashed box office records, swept the Academy Awards, and would become one of the most iconic and beloved movies of all time. Three quarters of a century after its 1939 debut, "Gone With the Wind" remains popular. We look back at the people who made "Gone With the Wind" an enduring classic.
