While modern blockbusters boast massive numbers, 'Gone with the Wind' remains the highest-grossing film of all time when adjusted for inflation. Released in 1939, the film was a massive production by David O. Selznick, featuring nearly 2,400 extras and a legendary search for the lead actress Scarlett O'Hara. Its success was sustained by multiple re-releases over several decades. In the era before home video, re-releasing popular films in theaters was the only way for audiences to see them again. When adjusted to current dollar values, its box office total is estimated to be over $3.9 billion, a figure that still eclipses modern hits like Avengers: Endgame and Avatar.
