The Shocking Casting Secret: Why They Were Chosen Over Other Twins

The role of Michelle Tanner was one of the most coveted in Hollywood, but the twins' casting came down to a simple, almost unbelievable factor. The producers and casting directors auditioned nearly a dozen sets of twins for the part.

The surprising truth? Mary-Kate and Ashley were the only babies who did not cry during the audition. At just nine months old, this calm demeanor on set was the deciding factor, ensuring the smooth production of the show. The twins were initially credited as "Mary Kate Ashley Olsen" to hide the fact that the role was shared by two actors, a common practice to comply with child labor laws.

The show's creator, Jeff Franklin, and the cast, including beloved "Uncle Jesse" John Stamos, quickly grew to love the young stars, despite the initial confusion and challenges of working with infants. The twins were fraternal, not identical, which led to minor continuity issues as they grew up, but their on-screen chemistry with the rest of the San Francisco-based Tanner family was undeniable.

From $2,400 to $80,000: The Explosive Salary Jump

While the Olsen twins are now worth a combined half-billion dollars, their start on Full House was humble, though still lucrative for infants. In the early seasons, the twins’ salary started at just $2,400 per episode.

However, as the show's popularity exploded, particularly their character Michelle Tanner, their value skyrocketed. By the later seasons of the show, their salary reportedly jumped to an astonishing $25,000 per episode. Other reports suggest their pay climbed even higher, reaching $80,000 per episode by the series finale in 1995.

This massive salary was reinvested into their burgeoning business empire, Dualstar Entertainment Group, which they co-founded in 1993. This company allowed them to produce and star in a string of highly successful direct-to-video movies, capitalizing on their massive fanbase. Dualstar was the engine that transformed their acting success into a business powerhouse, making them millionaires before they were teenagers.

The Real Reason They Skipped Fuller House

The most persistent question among fans of the original show and the Netflix reboot, Fuller House, is why Mary-Kate and Ashley Olsen were the only main cast members not to reprise their roles. The absence of Michelle Tanner was a running joke throughout the sequel series, but the real reasons are less about comedy and more about business.

The primary reason cited by executive producer Robert L. Boyett was that the twins wanted to "focus on their fashion business." Since 2006, their luxury brand, The Row, has been their sole professional focus, demanding their full attention. The timing for the reboot, which premiered in 2016, simply did not align with their commitment to their high-fashion empire.

There was also a reported misunderstanding with co-star John Stamos, who played Uncle Jesse. Stamos was initially "angry" when he heard they wouldn't return, believing they had been informed about the reboot and rejected it. This miscommunication caused a rift, although Stamos later apologized and has since shared rare throwback photos, confirming their relationship is amicable today.

Ultimately, the twins had completely moved on from acting, viewing their time on Full House as a cherished but closed chapter. Their focus remains squarely on The Row, which has achieved critical acclaim in the fashion world, solidifying their transition from Hollywood stars to serious entrepreneurs.

The Current State of The Olsen Twins’ Empire (2024)

In 2024, Mary-Kate and Ashley Olsen remain two of the most influential figures in fashion, maintaining a notoriously private lifestyle. They rarely grant interviews, a stark contrast to their childhood spent in the public eye.

Their company, The Row, is a billion-dollar luxury brand known for its minimalist aesthetic, high-quality materials, and elevated basics. The brand has won multiple Council of Fashion Designers of America (CFDA) awards, cementing their status as legitimate designers, not just celebrity vanity project owners. Their success is a testament to their dedication to craftsmanship and their decision to step away from the glare of the acting world.

The twins have successfully leveraged the foundation built by their Full House fame and the Dualstar company to create a sophisticated, enduring brand that is completely separate from their past. Their incredible combined net worth of $500 million is largely a result of this transition, proving that the quiet life of a fashion mogul can be far more rewarding—and profitable—than a life spent in front of the camera.

From being the only babies who didn't cry in the audition room to becoming two of the world's most reclusive and successful businesswomen, the story of the Olsen twins and Full House is a unique Hollywood phenomenon.
