Christian Bale has a new disguise—and no, it’s not a bat mask and cape.

The 51-year-old has undergone yet another total transformation for his role in the forthcoming Madden movie, where Bale plays late football executive and coach Al Davis.

In photos from the set for the sports movie—which also stars Nicolas Cage, John Mulaney, Sienna Miller and Kathryn Hahn—Bale is dressed in black pants, a black leather jacket and a white tee with a deep V-neck. He also sports three Super Bowl rings sparkling on his left hand and a gold pinky ring on the other.

It’s his face, however, where the transformation is most obvious. Instead of his usually full head of hair, Bale bears a balding hairline, the rest of his thinning hair brushed back. His complexion, too, has been made to look noticeably ruddy.

The film—which does not yet have a release date—follows the story of John Madden (Cage), the NFL commentator and football coach, as he embarks on creating the Madden NFL video game series.

This is not the first time Bale will have transformed himself for a movie. In fact, the actor’s filmography is riddled with roles that had him yo-yo between gaining and losing significant amounts of weight or donning prosthetics to change his appearance.

Among his most intense back-to-back alterations was 2004’s The Machinist, which saw him lose 63 pounds, only to put back 100 pounds within the next year for Batman Begins.

And in the years following, Bale made so many similar bodily changes that when it came time to film 2018’s Vice, which saw the British actor portray Vice President Dick Cheney, he finally decided to turn to a professional.

"It was the first time in my life that I realized I had to do this in a smart way," he said during a 2017 appearance on CBS Mornings. "I've lost weight, I've gained weight, [but] I never went to a nutritionist in my life. It was the first time that I said, 'You know what? I better really do this the right way.'"

He continued, "In the past for losing weight I went, 'Ah, I'll just smoke and drink whiskey and eat everything,' and it worked! But I'm in my mid-40s now and I just thought, 'Probably just eating cream puffs nonstop is not gonna be so good for my ticker.'"

And two years later at the premiere of 2019’s Ford vs. Ferrari, Bale admitted weight gain and loss for onscreen roles is officially a thing of his past.

“I've become a little bit more boring now,” he joked to E! News at the premiere. “Because I'm older and I feel like if I keep doing what I've done in the past I'm going to die. So, I'd prefer not to die.”

But Bale isn’t the only actor to undergo a metamorphosis for a role—read on for more of Hollywood’s biggest transformations.

The British actor packed on more than 40 pounds for his Oscar-nominated performance as a beer-bellied con artist in 2013's American Hustle. He put on the same amount to play former U.S. Vice President Dick Cheney in the 2018 movie Vice, which also earned him an Oscar nomination.

For his 2019 movie Ford v Ferrari, Bale dropped dropped 70 pounds to play slender race car driver Ken Miles. And it wasn't his first time losing weight for a role, having also lost about 30 pounds while filming the 2011 film The Fighter.

To transform the actress into her role of real life Appalachian grandmother Mamaw Vance in the 2020 film, makeup and special effects artist Matthew Mungle pulled Close's head cast from 2011's Albert Nobbs and sculpted her a new set of false ears and a false nose, according to Variety. The actress received an Oscar nomination for her role.

For his role as Donald Trump, not only did the actor work with the same hairstylist and makeup artists who transformed him into Tommy Lee for 2022's Pam & Tommy, but he also packed on the pounds to fill out the reality star-turned-president's frame.

Stan said he gained around 15 pounds by eating instant ramen mixed with soy sauce—a dish recommended by his nutritionist to look bloated in the face—and drinking soda.

The actress lost almost 40 pounds to play the iconic jazz singer in the 2021 film, which earned her an Oscar nomination.

Was eating, as his onscreen wife Emily Blunt joked "like, an almond every day," a bit nutty? Sure. But the Irish star really wanted to nail atomic bomb scientist J. Robert Oppenheimer's appearance.

"Oppenheimer had a very distinct physicality and silhouette, which I wanted to get right," he explained to The New York Times. "I had to lose quite a bit of weight, and we worked with the costume and tailoring; he was very slim, almost emaciated, existed on martinis and cigarettes."

At the 2004 Academy Awards, the gorgeous A-lister was honored with a Best Actress win for her chilling portrayal of real-life serial killer Aileen Wuornos. 

The actor lost 52 pounds to play the deeply disturbed Arthur Fleck, the man who would become Batman's adversary. The won the Best Actor Oscar in 2020 for his performance. 

It took three hours (and an infamously large prosthetic nose) for makeup artists to render the Best Actress winner completely unrecognizable for the 2002 drama. 

The actor shed 35 pounds and shaved his head to play an HIV-stricken attorney suing his former firm for wrongful termination. Hanks took home Best Actor at the 1994 Oscars, and made a similar transformation for his Oscar-nominated performance in 2000's Cast Away. 

The actress, who famously gained a reported 17 pounds to play the title role in Bridget Jones's Diary, did not have to change her physique to transform into Judy Garland for the 2019 film Judy, for which she won her first Oscar. You can thank the makeup and costume department for her transformation.

"Renée was extremely emotionally and artistically involved in Judy, the movie's costume designer, Jany Temime, who also worked on the Harry Potter films, told Vulture. "It was her film. I think she really got into Judy's skin."

Zellweger told the outlet, "Jany fit the costumes to Judy's posture. So the dresses didn't fit me unless I stood like I was supposed to stand. The zipper wouldn't go up."

Quite a departure from Robbie's sultry character in The Wolf of Wall Street, several prosthetics, braces and wigs helped the Best Actress nominee bring disgraced figure skater Tonya Harding's career-ending scandal to life in the 2017 flick. 

The Academy recognized McConaughey's extreme commitment to playing an HIV/AIDS stricken electrician with a Best Actor win during the 2014 ceremony. 

The late actor received a posthumous Oscar in 2008 for his chilling and mesmerizing performance as The Joker in the second film in Christopher Nolan's Batman trilogy. His look as the iconic villain differed greatly from those previously seen on past actors onscreen.

"What would it be if this guy slept in his makeup, this psychopath?" makeup artist John Caglione Jr. told IGN. "If he didn't spruce up his makeup for two or three weeks? He never changes his clothes It's those kinds of organic details that really helped."

He continued, "You think of a clown's makeup and for the most part, they're pretty detailed with sharp lines. But this had to be the opposite of that."

The two-time Oscar winner dramatically altered her appearance to play real-life transgender man Brandon Teena in the 1999 drama, and then again in Clint Eastwood's 2004 Best Picture winner.

In order to play British prime minister Winston Churchill, the 2018 Best Actor nominee spent upwards of four hours in the makeup chair every day and wore a "Victorian corset" style bodysuit. 

Before taking home Best Actress at the 2011 Oscars, the petite actress shed 20 pounds and trained up to 16 hours a day for her role as a mentally ill ballerina. 

Ever the chameleon, the 2014 Best Supporting Actor winner prepared to play a HIV-positive transgender woman by losing 40 pounds and only staying in character on set. 

"I had done similar things with weight, but this was different," Leto told E! News in 2013. "I think the role demanded that commitment…It was about how does that effect how I walk, how I talked, who I am, how I feel. You know, you feel very fragile and delicate and unsafe."

The Best Actress winner gained 15 pounds of muscle to play a mother who escapes years of captivity with her 5-year-old son (Jacob Tremblay) in the 2015 film. Larson said she even limited her exposure to the outside world, restricted nutrients like Vitamin D and tailored her eating habits to better grasp what her character experienced. 

At the 2012 Academy Awards, the typically fresh-faced starlet was honored with a Best Actress nomination for her performance in the thriller. Mara went as far as to pierce multiple body parts, bleach her eyebrows and chop her hair to transform into Lisbeth Salander.
