15 Actors Who Gained 100+ Pounds for Movies (And How)

Many performers will go to great extremes in order to authentically portray a character, often pushing their physical limits to meet the role’s specifications. Achieving weight gain of more than 100 pounds for a film is no easy task, necessitating unwavering commitment, significant dietary adjustments, and occasionally posing potential health complications.

In many instances, these dramatic changes take center stage, demonstrating the extraordinary lengths certain actors will go to ensure their portrayals are genuine. Here, I delve into fifteen performers who gained more than a hundred pounds for their respective roles, discussing their methods, outcomes, and the effects it brought about.

Christian Bale – ‘Batman Begins’ (2005)

Christian Bale is renowned for his dramatic physical transformations, and his body change for ‘Batman Begins’ was astonishingly impressive. After slimming down to a mere 120 pounds for ‘The Machinist,’ he had only six months to gain weight and build muscle to portray the muscular Bruce Wayne.

To accomplish this, Bale loaded up on calorie-rich foods such as pizza and ice cream, all while pushing himself intensely at the gym with heavy weightlifting. This quick bulk took a toll on his body, but it was instrumental in projecting Batman’s imposing physique.

Aamir Khan – ‘Dangal’ (2016)

In a remarkable metamorphosis, Aamir Khan left spectators speechless with his weight gain for the movie ‘Dangal.’ This film centered on an Indian wrestling coach. To convincingly play the mature, overweight Mahavir Singh Phogat, he bulked up to approximately 215 pounds, exceeding a hundred extra pounds.

Khan frequently indulged in energy-rich foods like samosas, desserts, and protein drinks, all the while minimizing physical activity to prevent losing those calories. Consequently, his weight gain became quite significant, causing him some mobility issues, but it significantly enhanced the authenticity of his performance.

Vincent D’Onofrio – ‘Full Metal Jacket’ (1987)

Vincent D’Onofrio significantly increased his weight for the role of troubled Private Leonard ‘Gomer Pyle’ Lawrence in ‘Full Metal Jacket.’ Some sources indicate that he almost doubled his weight, reaching nearly 100 pounds additional, with his final weight estimated to be approximately 280 pounds.

He consumed high-calorie meals such as steak, eggs, and milk every day, striving for a physical appearance that suggested a soldier who had let himself go a bit. Maintaining that weight was challenging, and losing it required several months of hard work.

Robert De Niro – ‘Raging Bull’ (1980)

Robert De Niro’s transformation for ‘Raging Bull’ is famously impressive, as he bulked up to approximately 60 extra pounds to play the older Jake LaMotta, although certain resources suggest he surpassed 100 pounds in total, reaching a weight of 215. The movie demanded a stark contrast between a svelte boxer and a heavier, retired character.

During a four-month hiatus from filming, De Niro immersed himself in meals rich with pasta and indulged in various desserts. This lifestyle choice lent a genuine, uncooked feel to his character’s later stages, ultimately securing him an Oscar.

Jared Leto – ‘Chapter 27’ (2007)

For the movie ‘Chapter 27’, Jared Leto significantly increased his weight to about 210 pounds, portraying John Lennon’s assassin, Mark David Chapman. Some estimates even suggest he approached 100 pounds of added weight. The character required a soft, unhealthy appearance.

In a quick attempt to increase his calorie intake, Leto consumed a mixture of melted ice cream, soy sauce, and olive oil. This hasty addition to his diet resulted in an accelerated weight gain, leading to health problems such as gout and mobility issues severe enough that he required a wheelchair on set.

Ryan Gosling – ‘The Lovely Bones’ (2009)

As a passionate film aficionado, I found myself utterly captivated by Ryan Gosling’s dedication in packing on around 60 lbs for ‘The Lovely Bones,’ striving to reach a hefty 210 lbs to convincingly portray a tormented father. However, some whispers suggested that he may have even surpassed the 100-lb mark in his pursuit of authenticity. Regrettably, his extraordinary commitment resulted in him being replaced from the project, making his struggle all the more bittersweet.

He ate softened ice cream and high-calorie meals while doing minimal physical activity. According to Gosling, this fit the character well, however, the director didn’t concur, resulting in him leaving the production.

Charlize Theron – ‘Monster’ (2003)

In the movie ‘Monster,’ Charlize Theron dramatically changed her appearance to portray serial killer Aileen Wuornos. She significantly increased her weight, with estimates suggesting she gained around 70 pounds, bringing her up to approximately 170 pounds. The character demanded a rough, disheveled look.

Theron frequently consumed fast food such as macaroni and cheese, day and night, sometimes even setting reminders for midnight snacks. This dietary habit, combined with the resulting transformation, significantly boosted her acting abilities, eventually earning her an Academy Award for Best Actress.

Matt Damon – ‘The Informant!’ (2009)

For the film ‘The Informant!’, Matt Damon intentionally added approximately 30 pounds to his weight to convincingly portray corporate whistleblower Mark Whitacre. Some reports even indicate that he gained up to 100 pounds, reaching around 190 pounds in total. The character required a more rounded, executive-type appearance.

Damon relished indulging in fast-food meals, particularly burgers, and drinking strong beers, doing so freely. He found this experience entertaining, yet acknowledged that afterward, he felt lethargic while working on set.

George Clooney – ‘Syriana’ (2005)

For the movie ‘Syriana’, George Clooney intentionally added approximately 30 pounds and some sources suggest he even went up to almost 100 pounds, bringing his weight close to 200 pounds. This significant weight gain made him appear significantly older for the part of a worn-out CIA agent.

He indulged in heavy calorie foods like pizza and pasta, shunned physical activity, and consequently, gained weight. However, Clooney found this method unpleasant, expressing feelings of despair and entrapment throughout the process.

Mark Wahlberg – ‘Father Stu’ (2022)

In the film ‘Father Stu,’ Mark Wahlberg bulked up to approximately 230 pounds, portraying a former boxer who later became a priest with a debilitating disease. While some sources claim he even surpassed the 100-pound mark, it was a challenging transformation for him at the age of 50.

He ate as much as 11,000 calories each day, having eight meals consisting mostly of carbohydrate-rich foods and protein shakes. Wahlberg admitted that this method put a significant strain on him, making him feel drained and achy.

Bradley Cooper – ‘American Sniper’ (2014)

For the movie ‘American Sniper,’ Bradley Cooper significantly increased his weight by approximately 40 lbs to depict Navy SEAL Chris Kyle. Some reports suggest he even got close to 100 lbs, reaching a total of 225 lbs. The part required him to have a physically imposing figure, much like a bear.

Every day, Cooper consumed approximately 5,000 calories, which consisted of protein bars and energy drinks, as he underwent intensive training sessions involving heavy lifts on two occasions. This demanding routine, though challenging, helped shape his appearance effectively.

Renée Zellweger – ‘Bridget Jones’s Diary’ (2001)

For the character of Bridget Jones in ‘Bridget Jones’s Diary,’ Renée Zellweger intentionally put on approximately 30 pounds, with some sources indicating she reached nearly 100 pounds in total, settling around 160 pounds to portray a more relatable Bridget. The role required a casual, everyday appearance.

In my own words, I’d say: Every day, I indulged in a whopping 4,000 calories, mostly pastries and rich, creamy dishes, while scaling back on my workout routine. Just like before, Zellweger followed suit for the sequel, fueling discussions about body image.

Chris Hemsworth – ‘Thor’ (2011)

For her role in ‘Million Dollar Baby,’ she bulked up an impressive 19 pounds of pure muscle, transforming into a determined boxer on screen. Rumors swirl that she even approached the 100-pound mark, ultimately weighing around 129 pounds. The part required raw strength and determination, and Swank delivered with unmatched dedication.
