Ask anyone to name the wealthiest actress in the world, and you’ll likely hear names like Angelina Jolie or Meryl Streep. Surprisingly, the title actually belongs to a star best known for her roles in 1980s cult classics.

With a reported net worth exceeding $3 billion, Jami Gertz sits atop the financial leaderboard, far outranking traditional A-listers.

Gertz was a staple of the 80s and 90s. Fans remember her vivid performances in The Lost Boys and the blockbuster Twister. She also charmed television audiences with memorable guest spots on Seinfeld and Modern Family.

However, her massive fortune didn’t come solely from Hollywood paychecks.

The secret to her wealth lies in a savvy partnership. In 1989, Gertz married financier Tony Ressler. She is quick to point out that she was the breadwinner when they met, paying for their first home and vacation.

Together, they built a financial empire. Ressler co-founded investment giants Apollo Global Management and Ares Management. The couple also ventured into sports ownership, acquiring the NBA’s Atlanta Hawks.

Gertz and Ressler are not just accumulating wealth; they are dedicated philanthropists. In 2012, they were named the year’s top charitable donors. Today, Gertz dedicates much of her time to the Melanoma Research Alliance and various educational causes.

While she stays relatively low-profile today, Jami Gertz proves that the most successful Hollywood story isn’t always about fame—it’s about smart investments and a strong partnership.
