Method acting, a craft that requires an actor to fully embody their character, was brought into the spotlight by Marlon Brando’s groundbreaking performance in “A Streetcar Named Desire” in 1951.
Since then, many actors have adopted this immersive technique, though a select few have pushed its limits to unsettling extremes, sometimes at the expense of their own well-being and their relationships with colleagues.
1. Ashton Kutcher’s Drastic Diet for ‘Jobs’
To capture the essence of Steve Jobs for his portrayal in “Jobs,” Ashton Kutcher adhered to a strict fruitarian diet. This extreme measure, intended to mirror Jobs’s own dietary habits, resulted in Kutcher suffering from pancreatitis and being hospitalized, highlighting the physical sacrifices some actors make for their art.

2. Shia LaBeouf’s Intense Approach in ‘Fury’
In “Fury,” Shia LaBeouf took method acting to new heights by refusing to bathe and even injuring himself to enhance his portrayal of a WWII soldier. His commitment to authenticity, while notable, made for an uncomfortable experience for his co-stars, including Brad Pitt.

3. Leonardo DiCaprio’s Grueling Role in ‘The Revenant’
For his role in “The Revenant,” Leonardo DiCaprio endured brutal conditions: battling frigid temperatures, sleeping in animal carcasses, and consuming raw bison liver. His relentless drive to portray the fur trapper Hugh Glass pushed him to the edge, resulting in a performance that earned him an Oscar and showcased the extremes of his dedication.

4. Michael Fassbender’s Drastic Weight Loss for ‘Hunger’
Michael Fassbender’s transformation to play Bobby Sands in “Hunger” involved a harrowing physical transformation. He embarked on a dangerously low-calorie diet, losing over 50 pounds, to authentically depict the effects of a prolonged hunger strike, highlighting the extremes actors go to in order to embody a character’s experience.

5. Jamie Foxx’s Commitment to ‘Ray’
In portraying Ray Charles, to authentically experience the musician’s blindness, Foxx had his eyes glued shut, later opting for prosthetics, in an effort to deeply connect with the character’s physical limitations and experiences.

6. Robert Pattinson’s Wet His Pants in ‘The Lighthouse’
In “The Lighthouse,” Robert Pattinson’s commitment to his role involved growling, eating mud, and even wetting his pants to portray a lighthouse keeper’s descent into madness. This intense approach to his character added a layer of authenticity to the film but also caused tension on set.

7. Charlize Theron’s put on a considerable amount of weight for ‘Monster
Theron, known for her striking beauty, underwent a staggering metamorphosis to portray serial killer Aileen Wuornos, a role that diverged dramatically from her previous work. She gained substantial weight, wore prosthetic teeth, and immersed herself in the psyche of Wuornos.
This transformation was not just skin deep; Theron delved into the emotional and mental state of her character, portraying the complexities of Wuornos’s troubled life with an intensity that blurred the lines between actor and role.

These six examples of method acting showcase actors’ willingness to push boundaries to bring authenticity to their roles, sometimes at the expense of their well-being and relationships with co-stars.
