In 1978, Robert De Niro was already the greatest actor of his generation — an Oscar winner for The Godfather Part II, the star of Taxi Driver and The Deer Hunter. But he was also, at 35, at risk of being typecast as the intense young tough guy. Then he decided to play Jake LaMotta, the self-destructive boxer, in Martin Scorsese’s Raging Bull (1980) — and to gain 60 pounds to play LaMotta in middle age. The transformation was so extreme it changed not just De Niro’s career but the very definition of Method acting. It won him a second Oscar and proved he would sacrifice everything for his art.
The Obsession
De Niro had been obsessed with Jake LaMotta’s autobiography, Raging Bull: My Story, for years. He saw in LaMotta — the Bronx boxer whose paranoia and violence destroyed his relationships — a character of Shakespearean complexity. He pitched it to Scorsese, who was initially reluctant. Scorsese didn’t like boxing, didn’t understand LaMotta, and was in the throes of his own personal crises.
“I didn’t want to do it,” Scorsese admitted. “But Bobby wouldn’t let it go. He kept saying, ‘Marty, this is the one. This is the role.’ He wore me down.”
What convinced Scorsese was De Niro’s vision: to show LaMotta’s rise and fall with unflinching honesty, to make the audience understand — if not sympathize with — a monster. And De Niro’s commitment: he would train as a boxer for the young LaMotta scenes, then gain 60 pounds for the older, bloated LaMotta.
“People thought I was crazy,” De Niro recalled. “Gaining 60 pounds? At 35? My doctor warned me. My wife begged me not to. But I knew: if I didn’t do it, the performance would be a trick. With the weight, it would be real.”
The Physical Sacrifice
De Niro’s transformation was unprecedented. For the young LaMotta — the hungry fighter of the 1940s — he trained with LaMotta himself, learning to box, building muscle, achieving a fighter’s physique. He sparred for months, took real punches, and developed the lean, coiled power of a middleweight contender.
Then production shut down for four months while De Niro gained the weight. He ate his way across France and Italy — pasta, bread, desserts — deliberately destroying the body he’d built. He went from 145 pounds to 205, developing the soft, sagging physique of a man who’s let himself go.
The health risks were serious. De Niro developed breathing problems, joint pain, and depression. His doctor monitored him closely. But De Niro insisted: LaMotta’s physical decay was his spiritual decay. You couldn’t act it; you had to live it.
“When I looked in the mirror at 205 pounds, I didn’t see Bobby,” De Niro said. “I saw Jake. The weight changed how I moved, how I breathed, how I felt about myself. That’s what LaMotta lived with — self-disgust. I needed to feel it.”
Scorsese filmed the boxing scenes first (young LaMotta), then the later scenes (old LaMotta) after the weight gain. The contrast is shocking — the same man, transformed from athlete to wreck. It’s not makeup; it’s De Niro’s actual body.
The Performance
De Niro’s LaMotta is a masterpiece of self-loathing. He plays the boxer as a man at war with himself — paranoid about his wife’s fidelity, violent toward his brother, incapable of tenderness. The famous scene where LaMotta, in prison, bangs his head against the wall screaming “I’m not an animal!” is devastating because De Niro makes you believe LaMotta is an animal — and knows it.
The domestic violence scenes are almost unbearable. LaMotta beats his wife Vickie (Cathy Moriarty) and his brother Joey (Joe Pesci) with a casual brutality that’s more frightening than any boxing match. De Niro doesn’t play LaMotta as evil; he plays him as damaged — a man who only knows how to express love through violence.
“He’s not a bad guy,” De Niro insisted. “He’s a sick guy. He loves his wife, but he doesn’t know how to show it except by controlling her. That’s tragedy.”
The final scene — an overweight, washed-up LaMotta in 1964, rehearsing his nightclub act, quoting Brando’s “I coulda been a contender” from On the Waterfront — is heartbreaking. De Niro, at 205 pounds, delivers the speech with a mixture of self-pity and self-awareness. He’s not just quoting Brando; he’s mourning his own wasted potential.
The Oscar and the Method
Raging Bull opened on December 19, 1980, to mixed box office but ecstatic reviews. Critics called it a masterpiece — Scorsese’s best film, De Niro’s best performance. The weight gain became legendary, setting a new standard for Method commitment.
When De Niro won his second Oscar (Best Actor), he thanked Scorsese and LaMotta. But the real victory was artistic: he’d proven that acting could be a form of physical sacrifice, that transformation wasn’t just emotional but corporeal.
The performance influenced a generation. Tom Hanks lost weight for Philadelphia and Cast Away. Charlize Theron transformed for Monster. Christian Bale became famous for yo-yoing weight. But De Niro did it first — and most extremely.
“I didn’t do it to start a trend,” De Niro said. “I did it because the role demanded it. If you want to understand a man who’s destroyed himself, you have to destroy yourself a little.”
The Turning Point’s Cost
The Raging Bull transformation changed De Niro’s career — but not entirely for the better. It cemented his reputation as the ultimate Method actor, but it also created expectations of extreme transformation that became a burden. He’d spend the 1980s and 1990s seeking roles that allowed similar intensity (Goodfellas, Cape Fear, Casino), sometimes at the cost of variety.
It also took a physical toll. De Niro has said the weight gain permanently affected his metabolism. And the emotional toll of playing such a dark character lingered.
“Jake stayed with me,” De Niro admitted. “The paranoia, the violence — I had to shake it off. It took months. That’s the danger of what I do. You go to dark places, and sometimes it’s hard to come back.”
But the turning point also gave De Niro artistic freedom. After Raging Bull, he could do anything — comedy (Midnight Run, Meet the Parents), drama, even musicals. He’d proven himself; now he could play.
The Legacy
Raging Bull is now considered one of the greatest films ever made — #4 on the AFI’s 100 Years list. De Niro’s performance is its heart: a man who punishes himself because he doesn’t know how to love himself.
The 60-pound weight gain remains the gold standard for acting commitment. But De Niro’s true achievement wasn’t physical; it was making Jake LaMotta — a violent, paranoid, abusive man — comprehensibly human.
“I didn’t want the audience to like Jake,” De Niro explained. “I wanted them to understand him. There’s a difference. Understanding doesn’t mean forgiving. It means recognizing his humanity, even when he’s inhuman.”
From young tough to transformative artist — Raging Bull didn’t just change Robert De Niro’s career; it changed what we expect from acting itself.
The Director Who Was Dying
The film almost died before it was born — along with its director. In the late 1970s, Martin Scorsese was in freefall: exhausted, unwell, nearly hospitalized, convinced his career was over after the commercial failure of New York, New York. He wanted nothing to do with a boxing movie. “I don’t understand this world,” he told De Niro. “I don’t like boxing. I don’t like Jake LaMotta.”
De Niro refused to take no for an answer. He visited Scorsese, argued for months, and finally said the words that changed everything: “Marty, this film will save your life.” Whether he meant it literally or artistically, he was right. Scorsese threw himself into Raging Bull with the fury of a man with nothing to lose — reinventing his visual style, shooting the fights like blood-soaked operas, filming in stark black and white — and emerged on the other side reborn. He has called it the film that saved him, and De Niro the friend who wouldn’t let him quit.
The Girl He Discovered
Casting Vickie LaMotta — Jake’s teenage bride, the object of his obsessive jealousy — nearly broke the production. Scorsese needed someone who could look 15 and 35, innocent and knowing, and hold the screen against De Niro at his most volcanic. De Niro found her himself: Cathy Moriarty, a 19-year-old with no acting experience, spotted in a New York club.
Moriarty was terrified — her first day on a film set, opposite the greatest actor alive, playing his wife. De Niro, who could be intimidating, became her protector, coaching her between takes. Her performance is extraordinary: watch the scene where Vickie calmly tells Jake she’s leaving, her voice steady while his world collapses. She earned an Oscar nomination for her debut — the only first-timer in the cast — and proved that De Niro’s eye for talent extended far beyond his own performances.
