Reception and legacy
Kidman is often regarded to be among the finest actresses of her generation. She is also considered one of Hollywood’s bravest performers. She has been noted for seeking eccentric roles in risky projects helmed by auteurs, as well as for her volatile performances and versatile work, having appeared in a variety of eclectic films from several genres throughout her extensive career spanning nearly four decades. Vanity Fair stated that, despite struggling with her personal life being publicly scrutinized by the media during the early years of her career, "[Kidman] has shown herself to be a major talent, a remarkable actress who can get in there with the best of them, go toe-to-toe, and come out with her credibility intact. What's more, she's proved herself to be a star with a capital S, the one-in-a-generation kind who, like Elizabeth Taylor, is bigger than the Hollywood system, and is also unafraid to be human and real, which only makes her more popular." According to The New York Times, "the plucky, disciplined indomitability she brings to her performances, even more than the artistry she displays within them, may be the secret of her appeal, the source of her bond with the audience."
Emily Nussbaum of The New Yorker commented how "in each role, there is something waxen and watchful and self-possessed about Kidman, so that, even when she's smiling, she never seems liberated. While other actors specialize in transparency, Kidman has a different gift: she can wear a mask and simultaneously let you feel what it's like to hide behind it." Kidman’s most remarkable accomplishment lies in her ability to consistently deliver surprising performances, often standing out as the highlight even in otherwise lackluster projects. She remains a captivating figure, sparking more conversation and strong opinions than nearly anyone else in the industry. Leila Latif of The Guardian commented that Kidman continuously proved again and again "why she is one of Hollywood’s best and subtly most transgressive stars." In 2004 and 2018, Time magazine named Kidman one of the 100 most influential people in the world on their annual Time 100 list. In 2020, The New York Times ranked her fifth on its list of the greatest actors of the 21st century, and in a 2022 readers' poll by Empire magazine, she was voted one of the 50 greatest actors of all time. In 2025, Kidman was named one of the Women of the Year of Time magazine.
Some media outlets have commended Kidman for continuing to defy age-related stereotypes in Hollywood and thriving in an industry often criticized for its challenges for women over 50. Some have commented on her ability to secure leading roles and produce compelling work highlighting her resilience and determination and proving that age is no barrier to success in her career, and have also said that her journey inspires, challenging the industry’s norms and paving the way for other women in Hollywood.
Kidman is known to practice method acting for many of her roles. It has been noted that she oftentimes transforms herself physically, mentally and emotionally to resemble her characters, to the point where it has adversely affected her health. Mark Caro from the Los Angeles Times stated that "to Nicole Kidman, acting isn't a mere technical feat; it's the art of transformation. To hear her tell it, the change can be as dramatic as a caterpillar-into-butterfly metamorphosis. She'll be working and working to get under the skin of a character." W described her as a "cipher", and pointed out how "she gets under her character's skin so thoroughly, it's nearly impossible to distinguish the actress from the role. It's why she has become so synonymous with a few key roles ... and why those films are so defined by Kidman's presence in them."
Scholars have also commented on her acting style and approach to roles. Sharon Marie Carnicke, a professor of critical studies and acting at the USC School of Dramatic Arts, mentioned that "Kidman's [acting] choices are believable and natural as reactions to the specific circumstances in her world" and described her work as "kinetic". Dennis Bingham, a professor of English and director of film studies at Indiana University–Purdue University Indianapolis, stated that "Kidman acts always a step or two outside the character, telegraphing her reactions, elongating the time she takes to articulate her decisions and conclusions. Even her emotional responses are presented as signs." Pam Cook, a professor of film at the University of Southampton, suggests in her biography of Kidman that "her emphasis on artifice and technique points to a conception of screen acting that looks to cinematic expression rather than to the actor's body and intentions for the realization of character." Mary Luckhurst, a professor and head of the University of Bristol School of Arts with credentials in theatre and performance, stated how "she has strategically pursued a high-risk mutability and versatility, and regularly traverses between naturalist and non-naturalist roles and artforms." She continues saying that "she can continually test her own emotional limits, physical skills, politics, values and frames of reference" and mentions how "her conception of character acting involves metamorphosing gradually into something that she feels is so 'other' that she frequently speaks of losing herself or getting lost in the role, and her preparedness to challenge herself in this respect has continually surprised other actors, directors and producers."
After nearly four decades in the industry and over 80 film and TV projects, Kidman emphasizes her acting approach, saying, "I still approach acting like I’ve just come out of drama school."
Arte France released a 53-minute documentary in 2023, Nicole Kidman – Eyes Wide Open.
Kidman has also been described as a fashion icon. The chartreuse Dior gown she wore to the 1997 Academy Awards is regarded as one of the greatest dresses in Oscar history and has been credited with changing red carpet fashion forever. Vogue described how "from her embroidered chartreuse John Galliano for Christian Dior gown in 1997, at the side of then-husband Tom Cruise, to that impeccable red Balenciaga moment at the 2007 Oscars, to the unforgettable Calvin Klein ballerina dress she wore to the 2017 Cannes Film Festival, the Australian native has mastered the art of red carpet dressing, always piquing our [interest] and taking risks while never overdoing it." Insider stated that "over the years, Kidman has experimented with all sorts of trends, including bold colors, statement jewelry, and everything in between, making herself one of the most iconic celebrities when it comes to her fashion choices." In 2003, she received the Fashion Icon Award, which was awarded to her by the Council of Fashion Designers of America. Regarding her bestowal, Peter Arnold, executive director of the CFDA, said, "Nicole Kidman's style, both on and off the screen, has had an undeniable impact on fashion. As an actress, she has developed her many memorable characters with an innate understanding of the artistry of clothes. At the same time, she has elegantly established her personal style and own iconic presence worldwide."
