"Gone with the Wind" may be the highest-grossing film of all time, when adjusted for inflation over the 78 years since the film's first release, but nothing can hold a candle to the empire that Star Wars created. Spurring at least 10 sequels and six TV series (so far), as well as billions of dollars in merchandise, it's unlikely that filmmaker George Lucas could've seen just how successful his creation would become in the intervening 40 years.
