Only 5 directors are worth over $1 billion. Here they all are.

Thanks to "Titanic" and the "Avatar" franchise, both of which spent some time as the highest-grossing movies of all time, Cameron has crafted a lucrative empire.

Thanks to the stage, film, and TV productions surrounding his character Madea, and the 330-acre movie studio he created in Atlanta, Tyler Perry is the richest Black filmmaker of all time.

Peter Jackson went from making low-budget horror movies to helming one of the most successful franchises of all time with "The Lord of the Rings." It was a massive commercial and critical success, with Jackson collecting Oscars for best picture, best director, and best adapted screenplay.

One of the architects of the modern Hollywood blockbuster, George Lucas' "Star Wars" franchise didn't just change the movie business forever, it also change how creatives can monetize their work. By demanding to own the merchandising and sequel rights to "Star Wars," which movie studios saw as losses back in the late 1970s, Lucas pulled the ultimate fast one on the establishment.

Out of the "Hollywood brats" who redefined the movie business in the 1970s, Steven Spielberg remains the last to consistently produce massive event movies to this day. His credits — "Jaws," "Close Encounters of the Third Kind," "E.T.," the "Indiana Jones" franchise, the "Jurassic Park" franchise — didn't just make him a billionaire; they unlocked the imaginations of generations of people.
