Kristin Miller | October 17, 2024 3:07 pm

Call it whatever you want - method acting, dedication to their craft, or straight up insanity - actors will give anything to pull off a role, sometimes transforming into a completely different person. That means dropping massive amounts of weight in shockingly short time frames, shaving off all their hair or spending hours upon hours in the makeup chair. Check out these most outrageous transformations in film history and the crazy lengths these celebs went to achieve their new look.

A Real Psycho Diet

Christian Bale caused jaws to drop thanks to his incredible bod in 2000s cult classic, American Psycho. His perfectly chiseled abs, strong arms and overall hunkiness had all the girls loving him and all the guys wanting to be him. He credits this role with teaching him the workout foundations he would later use during his Batman bulking-up days. But it was also his hardest transformation. Bale says, "Not including The Machinist, Rescue Dawn or The Fighter – where I had to lose weight – my role for American Psycho was my most restrictive diet-wise. There were no cheat meals. It was all lean protein. No sugars, good fats and low carbs."

For his final film, Heath Ledger took on the most drastic transformation of his career. Ledger gave the performance of a lifetime using Method acting to transform his thoughts, body language and physical appearance into that of the Jokers'. "I sat around in a hotel room in London for about a month, locked myself away, formed a little diary and experimented with voices — it was important to try to find a somewhat iconic voice and laugh. I ended up landing more in the realm of a psychopath — someone with very little to no conscience towards his acts," he explains. Each day as he was in makeup, Ledger would read the diary and let the transformation unfold.

He was supposed to stop at 145 but kept going until he got the reaction he wanted. He told Vanity Fair that people kept asking him if he was okay or suggesting he seek help and he said, “There we go. That’s the perfect spot.” He won an Oscar for his heart wrenching performance.

Avant-garde actress Tilda Swinton is almost unrecognizable in Amy Schumer's hit film Trainwreck. Portraying the sexy yet slightly deranged editor-in-chief of raunchy men's magazine, Tilda dons a long blond wig, heavy amounts of makeup and a serious spray tan - completely uncharacteristic of her usual bare-bones makeup approach and translucent skin. She spent hours in the makeup chair each day applying self tanner, heavy amounts of eye makeup and a wig. The film's makeup artist describes the process - “She’s [normally] translucent, and we turned her the color of a coconut shell each day,” says explained.

Hollywood hunk Matt Damon turned into a bit of a frump for the filming of The Informant in 2009. The actor packed on somewhere between 20 and 30 pounds. To achieve his doughy physique he binged on Doritos, McDonald's and lots of beer with little to no exercise. He described this phase of letting himself go as "absolute heaven." He told the Daily Mail, "It was very, very easy to gain the weight. It was very, very fun, probably the funnest time I had working, because I didn't have to go to the gym after work and I just ate everything I could see."

The king of crazy transformations, Christian Bale then went on to drop between 55 and 60 pounds for his role in 2004’s The Machinist. Existing on coffee, apples and one can of tuna a day he was able to drop the weight in just a few short months. Even crazier - six months after filming ended, he gained over 100 pounds for his role in Batman by carbo loading and hitting the gym hard. Bale was apparently annoyed that his weight loss and gain overshadowed some of his performances in both films. You can't deny that he's one of the hardest-working actors in the business.

The blond bombshell is completely unrecognizable for her role as real-life serial killer Aileen Wuornos, who was executed in 2002 for murdering six men. Theron reportedly gained 30 pounds for the role, wore minimal makeup and prosthetic teeth. She also had her skin layered with washed-off tattoo ink to give it a weathered, chapped appearance and her eyebrows were partially shaved off and bleached out. Don’t worry - she won an Academy Award for the performance and was voted the World’s most desirable woman that year. It sure must have been refreshing to wash that makeup off every night, though.

Gyllenhaal transformed his relatively slight stature into a total brawny badass for the the 2015 film Southpaw, bulking up from 145 pounds to 175 in just six months.

His workout regimen consisted of at least 2,000 sit ups a day, push-ups, dips, flipping 350 pound tires, and running eight miles five days a week.

The process was grueling but overall Jake attributes it with giving him more confidence and allowing him to better deal with stress and anxiety.
