Actress Olivia Munn has come forward with her own story of dealing with a difficult co-star, adding her voice to a conversation about on-set professionalism that Rebecca Ferguson sparked earlier this year.

Ferguson, known for her roles in the "Mission: Impossible" and "Dune" franchises, previously described working with what she called an "absolute idiot of a co-star" who screamed at her in front of the entire crew. The Swedish actress never publicly identified the person involved, but her account resonated widely within the industry and among fans who have long suspected that toxic behavior remains a problem on Hollywood sets.

According to Dark Horizons, Munn has now shared a similar experience from her own career, though specific details about the incident—including which production it occurred on and when—have not been disclosed. The actress, whose credits include "The Newsroom," "X-Men: Apocalypse," and most recently Marvel's "Deadpool & Wolverine," has worked across television and film for nearly two decades.

A Pattern of Silence

What makes both Ferguson's and Munn's accounts particularly notable is what they don't say. Neither actress has named the individuals involved, a pattern that reflects the complicated dynamics of speaking out in an industry where professional relationships and future opportunities can hinge on discretion.

This careful approach stands in contrast to the #MeToo movement's emphasis on naming abusers, suggesting that while attitudes toward harassment and assault have shifted significantly, addressing garden-variety unprofessional behavior remains thornier territory. Stars who speak out risk being labeled "difficult" themselves or damaging relationships with powerful producers, directors, and studios.

"The culture of silence around bad behavior that doesn't rise to the level of assault or harassment is still very real," said one industry insider who requested anonymity. "People will share these stories privately, but going public—even without names—takes courage."

The Broader Context

The entertainment industry has grappled with workplace conduct issues for years, particularly following the 2017 revelations about Harvey Weinstein that launched the #MeToo movement. While that reckoning primarily focused on sexual misconduct and abuse of power, it also opened the door to broader conversations about what constitutes acceptable behavior on set.

Several high-profile figures have faced consequences for creating hostile work environments. Director Joss Whedon faced multiple allegations of abusive behavior from actors on "Buffy the Vampire Slayer" and "Justice League." Ellen DeGeneres's talk show ended amid reports of a toxic workplace culture. More recently, actor Jonathan Majors was convicted of assault and harassment, leading to his removal from Marvel projects.

Yet for every public reckoning, industry veterans say countless incidents of screaming, belittling, and unprofessional conduct go unreported or unaddressed, particularly when the person behaving badly has significant power or box office draw.

Changing Expectations

The willingness of actors like Ferguson and Munn to share their experiences—even in limited form—signals a shift in what's considered acceptable workplace behavior in Hollywood. Younger generations of actors and crew members increasingly expect professional standards that previous generations might have dismissed as "just how things are."

Actors' unions, including SAG-AFTRA, have strengthened protections around workplace conduct in recent contract negotiations. The 2023 strike that brought Hollywood to a standstill included discussions about artificial intelligence and residuals, but also touched on working conditions and the treatment of performers on set.

"There's a growing recognition that you can make great art without screaming at people," said a veteran producer who has worked on both television and film productions. "The old idea that genius excuses bad behavior is finally dying."

The Cost of Speaking Out

Still, the fact that both Ferguson and Munn declined to name names illustrates the professional risks that remain. In an industry built on relationships and reputation, even justified criticism can have career consequences.

Munn herself has been candid about other challenges in her career, including her 2023 breast cancer diagnosis and subsequent treatment. She has used her platform to discuss health issues and women's experiences in Hollywood, making her latest disclosure consistent with a pattern of openness about difficult topics.

Ferguson, meanwhile, has continued to work steadily in high-profile projects despite—or perhaps because of—her willingness to speak about negative experiences. Her refusal to tolerate mistreatment may have resonated with filmmakers looking to create healthier work environments.

What Comes Next

As more actors share stories of on-set misconduct, pressure may build for the industry to address these issues more systematically. Some productions have implemented "no asshole" policies, while others have hired monitors or advocates to address workplace concerns in real time.

Whether these measures prove effective remains to be seen. Hollywood has long operated on a star system that concentrates power in the hands of a few bankable names, making it difficult to hold those individuals accountable when their behavior crosses lines.

For now, Ferguson and Munn's decision to share their experiences—even in limited form—contributes to a growing record of what many in the industry have long known: that talent and success don't excuse treating colleagues with disrespect. Whether that record translates into meaningful change will depend on the willingness of studios, producers, and other powerful figures to prioritize workplace culture alongside box office returns.
