She appeared in films such as The Lost Boys, Sixteen Candles, and Twister, but her acting career is not the main source of her wealth. Most of it comes from business and investments connected to her husband, billionaire investor Tony Ressler.
Ressler co-founded major private equity firms and has significant financial interests, including ownership stakes in professional sports teams like the Atlanta Hawks.
However, Gertz has emphasized in interviews that she was financially successful on her own before her marriage and contributed to their early life together.
Beyond wealth, the couple is known for philanthropy, donating millions to education, healthcare, arts programs, and medical research initiatives.
What makes her story stand out is the contrast between extreme wealth and low public visibility. Despite being the richest actor, she is not a constant presence in entertainment headlines.
Her case shows how modern celebrity wealth can come from far outside traditional Hollywood success.
