Nicole Kidman & More of the Biggest Oscars Transformations

For Nicole Kidman, becoming Virginia Woolf was practically magic.

Before filming The Hours in 2002, the actress thoroughly researched the novelist she was portraying, learning details like how she made her own cigarettes and even which hand she wrote with.

She told the San Francisco Chronicle that she felt like she was finally letting go of pent-up emotions. She explained she’d always kept a lot to herself, but was now ready to be completely vulnerable and share everything, even if it meant being emotionally raw.

She perfectly captured the way Virginia Woolf spoke and carried herself, even mimicking her accent. This dedication, along with a transformation in her appearance – including a prosthetic nose and a change from red curls to natural brown hair – paid off when she won the Best Actress Oscar in 2003. She truly became someone else.

She admitted she liked being anonymous, adding with a smile, “It was great being able to leave my trailer without being recognized.”

Nicole, who was 35 at the time, understood that playing Virginia in the film—which featured stars like Meryl Streep, Julianne Moore, and Claire Danes—would require a deep transformation, not just a change in appearance.

Nicole explained to the Los Angeles Times in 2003 that she focused on embodying the character internally, rather than relying on physical changes like the prosthetic nose. She saw those external elements as additions to the core of who the character was, not the starting point.

Looking back on the filming experience, she described living in a secluded cottage as feeling almost unhinged. She was immersed in the letters and books of Virginia Woolf, and enjoyed long walks in the woods. It was a peaceful existence, but she was also personally struggling with difficult issues like loneliness, and she found those feelings deeply connected to the character she was playing.

Nicole isn’t the only actor to dramatically change their appearance for an Oscar-winning role. From Christian Bale in American Hustle to Cillian Murphy in Oppenheimer, here are some other actors who surprised audiences with how different they looked.

The British actor famously gained over 40 pounds twice for his roles in two movies. First, he did it for his performance as a con artist in the 2013 film American Hustle, earning an Oscar nomination. He then gained the same amount of weight to portray former U.S. Vice President Dick Cheney in the 2018 movie Vice, which also led to an Oscar nomination.

Christian Bale famously transformed his body for roles. For his 2019 film Ford v Ferrari, he lost 70 pounds to portray the lean race car driver Ken Miles. This wasn’t the first time he’d dramatically changed his weight for a part—he also shed around 30 pounds while making the 2011 movie The Fighter.

For the 2020 film, makeup artist Matthew Mungle used a mold of Glenn Close’s head from the 2011 movie Albert Nobbs to create prosthetics – a new set of ears and a false nose – to help her transform into her character, Mamaw Vance, a real-life Appalachian grandmother. Close received an Oscar nomination for her performance, as reported by Variety.

To play Donald Trump, the actor reunited with the hair and makeup team who previously turned him into Tommy Lee for the series Pam & Tommy. He also gained weight to more closely resemble Trump’s build.

Stan intentionally gained about 15 pounds by following his nutritionist’s advice: he ate a lot of instant ramen with soy sauce and drank soda to make his face appear fuller.

To portray the famous jazz singer in the 2021 film, the actress lost nearly 40 pounds, a performance that led to an Oscar nomination.

It might have seemed a little extreme that he was reportedly eating just one almond a day, as his co-star Emily Blunt playfully pointed out. But the actor was serious about accurately portraying the physical appearance of J. Robert Oppenheimer, the atomic bomb scientist.

Cillian Murphy, who played Oppenheimer, described how important it was to capture the physicist’s unique appearance. He told The New York Times that he lost a significant amount of weight and worked closely with the costume designers to achieve the right look, noting that Oppenheimer was very thin, almost gaunt, and had a habit of living on a diet of martinis and cigarettes.

The acclaimed actress won an Academy Award for Best Actress in 2004 for her powerful and unsettling performance as real-life serial killer Aileen Wuornos.

To portray the troubled Arthur Fleck, the future Joker, the actor lost 52 pounds. He received the Best Actor Oscar in 2020 for his compelling performance.

Makeup artists spent three hours transforming the Best Actress winner with extensive makeup, including a large prosthetic nose, making her almost unidentifiable in the 2002 film.

To convincingly portray an attorney with HIV suing his old company, the actor lost 35 pounds and shaved his head. He won the Best Actor Oscar in 1994 for this role, and also underwent a significant physical transformation – losing weight and growing a beard – for his Oscar-nominated performance in the 2000 film Cast Away.

The actress famously gained weight for her role in Bridget Jones’s Diary, but she didn’t need to change her body to play Judy Garland in the 2019 film Judy. She won her first Oscar for the performance, and the incredible transformation was achieved through expert makeup and costumes.

Renée had a strong connection with Jany Temime, the costume designer for the film, who also designed the costumes for the Harry Potter movies, Vulture reports. Temime said, “It felt like the film was deeply personal for Renée, as if she truly understood and embodied Judy’s character.”

Renée Zellweger explained that the costumes for the film were tailored to mimic Judy Garland’s specific posture. This meant the dresses wouldn’t fit properly on Zellweger unless she adopted Garland’s stance, and sometimes she couldn’t even zip them up.

Margot Robbie transformed herself for the role, using prosthetics, braces, and wigs to portray the controversial figure skater Tonya Harding and the scandal that ended her career in the 2017 film. It was a significant change from her glamorous role in The Wolf of Wall Street.

In 2014, Matthew McConaughey won the Best Actor Oscar for his dedicated performance as an electrician living with HIV/AIDS.

Heath Ledger won an Oscar after his death in 2008 for his unforgettable and captivating portrayal of The Joker in Christopher Nolan’s second Batman movie. His version of the famous villain was a striking departure from previous on-screen interpretations.

Makeup artist John Caglione Jr. wondered to IGN what would happen if the character didn’t bother with his appearance. “If he slept in his makeup for a couple of weeks, or never changed his clothes… those little realistic details really brought him to life.”

He explained that when you picture clown makeup, it’s usually very precise and uses strong, defined lines. But this particular makeup was completely different – it was meant to be the opposite of all that.

The Academy Award-winning actress transformed her look to portray Brandon Teena, a real-life transgender man, in a 1999 film, and then did so again in Clint Eastwood’s 2004 Best Picture-winning movie.

To transform into Winston Churchill for the role, the actor—nominated for Best Actor in 2018—spent over four hours each day getting makeup applied and wore a special bodysuit similar to a Victorian corset.

To win Best Actress at the 2011 Oscars, the actress lost 20 pounds and dedicated up to 16 hours a day to preparing for her demanding role as a ballerina struggling with mental illness.

Jared Leto, known for his transformative roles, won the Best Supporting Actor award in 2014 after preparing to play a transgender woman living with HIV by losing 40 pounds and fully embodying the character only while filming.

I’d transformed my body for roles before, but this was a completely different experience,” Jared Leto explained to TopMob News in 2013. “The part really required that level of dedication. I focused on how it would change my movement, my speech, my entire persona, and my emotions. It left me feeling vulnerable, fragile, and insecure.

The actress who won Best Actress physically transformed for her role, gaining 15 pounds of muscle to play a mother escaping captivity with her 5-year-old son, Jacob Tremblay, in a 2015 film. To fully understand her character’s experience, she also deliberately limited her social interaction and restricted her diet, even avoiding nutrients like Vitamin D.

Rooney Mara received a Best Actress nomination at the 2012 Oscars for her role in the thriller. To fully embody the character of Lisbeth Salander, she went to great lengths, including getting multiple piercings, bleaching her eyebrows, and cutting her hair.
