From Method To Madness
Method acting is one thing, but some actors crank it up to 11, living as their characters even when the cameras stop rolling. Sometimes, their commitment to a role is inspiring, sometimes it’s downright weird, but it’s always fascinating. Here are 20 actors who famously (or infamously) lived like their characters off-screen.
Daniel Day-Lewis
For My Left Foot (1989), Day-Lewis played Christy Brown, who had cerebral palsy. Off camera, he refused to break character, staying in a wheelchair and being spoon-fed by crew members. He even insisted on staying hunched over so long he broke two ribs. Legendary dedication—or legendary stubbornness, depending on who you ask.

Jamie Foxx
For Ray (2004), Foxx had prosthetics glued to his eyelids so he couldn’t see, keeping him blind between takes. He also mimicked Ray Charles’s stooped walk and even insisted crew help guide him around the set. At one point, he reportedly stayed blind for so long he began having panic attacks off camera.

Jim Carrey
For Man on the Moon (1999), Carrey embodied Andy Kaufman so completely he refused to be addressed as "Jim" at all. Cast and crew had to treat him as Kaufman—or Kaufman’s alter ego Tony Clifton—even off set. Behind-the-scenes footage shows Carrey chain-smoking, heckling, and wandering the set in character, driving everyone insane for months.

Heath Ledger
Ledger immersed himself in chaos for The Dark Knight (2008). He locked himself in a hotel room for weeks to craft the Joker’s voice and laugh, and he kept a diary filled with unsettling thoughts. Rumors suggest he rarely left character on set, unnerving crew members with his unsettling mannerisms and constant dark energy.

Adrien Brody
For The Pianist (2002), Brody went all in. He sold his apartment, gave up nearly all his possessions, and moved to Europe with just two bags to understand loss. He lost over 30 pounds, isolated himself, and practiced piano four hours a day. Off camera, he lived in near-poverty to capture the despair of Władysław Szpilman.

Jared Leto
For Suicide Squad (2016), Leto’s Joker antics went way beyond the screen. He reportedly sent co-stars bizarre gifts like bullets, used adult toys, and even a dead rat to Margot Robbie. On set, he insisted on only being addressed as “Mister J” and allegedly never broke character, much to the annoyance of his castmates.

Jeremy Strong
Strong has become notorious for his ultra-serious approach in Succession. Colleagues claim he doesn’t see it as “acting” but “living”. He kept Kendall Roy’s anxiety, posture, and mannerisms alive even at lunch breaks. Fellow cast members sometimes joked—or complained—that Strong was impossible to separate from Kendall during filming.
Robert De Niro
De Niro is old-school method. For Taxi Driver (1976), he actually drove a cab around New York for weeks to soak up the city’s grit. For Raging Bull (1980), he trained as a boxer and then gained 60 pounds to play Jake LaMotta later in life. Off-camera, he reportedly stayed abrasive and moody to match his character.
Columbia Pictures, Taxi Driver (1976)
Christian Bale
Bale doesn’t just play characters, he becomes them. For The Machinist (2004), he dropped over 60 pounds, staying skeletal even when cameras stopped rolling. Then, for American Hustle (2013), he gained weight and adopted a slouch that he reportedly carried off set. Cast and crew have often said Bale essentially lived as his characters during shoots.

Lady Gaga
Gaga lived as Patrizia Reggiani for House of Gucci (2021) for nine months straight. She never broke the Italian accent, on or off camera, and said she started to “think like” Patrizia even at home. Crew members said they stopped hearing Gaga’s normal voice entirely during production—it was Reggiani, 24 hours a day.

Kate Winslet
Winslet has admitted she sometimes struggles to “shake” roles. During The Reader (2008), she kept her German accent and Holocaust-era trauma even at home. After Mare of Easttown, she said she caught herself slipping back into her character’s gruff Philly accent in everyday life. It’s not as extreme as some, but it shows real bleed-through.

Al Pacino
Pacino’s intensity doesn’t always turn off. On films like Dog Day Afternoon (1975) and Serpico (1973), colleagues recall him staying edgy, paranoid, or temperamental between takes. Allegedly, during Scarface (1983), he was so locked into Tony Montana’s manic energy that he scared extras at lunch breaks. For Pacino, the line between acting and reality often blurred.
Warner Bros., Dog Day Afternoon (1975)
Marlon Brando
Brando practically invented staying in character. On The Godfather (1972), he walked around set constantly as Vito Corleone, cotton in his mouth and all. During Apocalypse Now, he allegedly brooded off set in the same bizarre, enigmatic way as Colonel Kurtz. Directors alternately called him a genius and a nightmare to deal with.
Paramount Pictures, The Godfather (1972)
Joaquin Phoenix
Phoenix is notorious for disappearing into roles. While filming Joker (2019), he kept Arthur Fleck’s emaciated body and unsettling laugh even off set. Crew members described him as distant, awkward, and twitchy between takes. Friends say the role haunted him for months afterward, blurring where Phoenix ended and the Joker began.

Leonardo DiCaprio
In The Revenant (2015), DiCaprio didn’t just act like a man freezing in the wilderness, he lived it. He slept inside animal carcasses, ate raw bison liver, and stayed in freezing rivers until his body shook uncontrollably. Off camera, he kept the physical toll visible, sometimes dragging himself around set as though he’d really been mauled by a bear.
20th Century Fox, The Revenant (2015)
Tom Hanks
For Cast Away (2000), Tom Hanks didn’t just play a stranded man, he practically became one. To capture Chuck Noland’s isolation, Hanks lost over 50 pounds and grew out his hair and beard while production took a break. He lived with the discomfort of hunger and exhaustion, and carried the weathered look and survivalist mindset off-set, embodying the character long after “cut” was called.
20th Century Fox, Cast Away (2000)
Viggo Mortensen
Mortensen went full survivalist for Captain Fantastic (2016), living in the woods, chopping wood, and cooking over open fires even when not filming. On The Lord of the Rings (2001), he carried Aragorn’s sword everywhere (including to the grocery store) and even slept in costume to stay rugged. His co-stars joked he was Aragorn, 24/7.
Bleecker Street, Captain Fantastic (2016)
Nicolas Cage
Cage calls his style “nouveau shamanic” and it shows. For Birdy (1984), he wore bandages and plasters on his body for weeks off set to simulate wartime injuries, even developing skin infections. For Vampire’s Kiss (1989), he allegedly lived like he truly believed he was a vampire, hissing at strangers and eating a live cockroach on camera.
TriStar Pictures, Birdy (1984)
Shia LaBeouf
LaBeouf has gone off the deep end with method. For Fury (2014), he lived on set in a tank, refused to shower, and even cut his own face so the scars looked real. Castmates said he often smelled terrible but refused to break character. Rumor has it he even pulled out a tooth for authenticity.
Columbia Pictures, Fury (2014)
Dustin Hoffman
Hoffman famously stayed up for days to look exhausted in Marathon Man (1976). Co-star Laurence Olivier quipped, “My dear boy, why don’t you try acting?” But Hoffman’s intensity didn’t stop there: he allegedly stayed jittery and paranoid off set, carrying his character’s constant fear with him long after the cameras stopped rolling.
