The core difference isn't talent or fame—it's estate strategy. Audrey's family and executors aggressively licensed her image across fashion, perfume, and merchandise, treating her likeness as a renewable asset. Marilyn's $1M valuation appears artificially low because her estate's $8M annual revenue streams aren't capitalized into net worth the same way. If Marilyn's annual earnings were valued at even a conservative 5x multiple, her estate would exceed $40M. The math reveals a brutal truth: Audrey's advisors monetized her image while Marilyn's did not.

Career timing and contract structure created the divergence too. Audrey worked steadily into the 1980s and maintained control over her brand's use in her final decades. Marilyn died at 36 with unresolved contracts and tangled rights. By the time her estate could capitalize on her image, the machinery was rusty. Audrey's later years gave her leverage to negotiate better deals and establish cleaner IP ownership—she literally built the foundation for her $55M estate while alive.

Today, Marilyn actually generates more annual cash ($8M) than Audrey's estate likely does, but nobody capitalized that value during the critical decades after her death. Audrey's executors reinvested early licensing revenue into brand expansion; Marilyn's never had that moment. It's a $54M lesson in the difference between dying famous and dying with a business plan.
