From “Chunk” to Power Player: The Remarkable Journey of Jeff Cohen
The Kid Everyone Remembered
Anyone who grew up in the 1980s remembers Chunk.
The Hawaiian shirt. The unforgettable Truffle Shuffle. The lovable whirlwind of chaos who effortlessly stole scenes in The Goonies.
Jeff Cohen became a pop culture fixture almost overnight, and his performance left a lasting impression that continues decades later.
But the story behind the child star is far more surprising than many fans realize.
A Childhood Marked by Change
Jeffrey Bertan McMahon was born on June 25, 1974, in Los Angeles.
His early years were shaped by personal upheaval when his parents separated while he was still very young.
The experience left a lasting impact on him.
Not long after, he made a defining choice for his professional life by adopting “Cohen” as his stage surname, honoring his mother Elaine’s maiden name.
Early Steps Into Television
Before becoming widely known for The Goonies, Cohen was already building experience in front of cameras.
In 1982 and 1983, he appeared on the CBS game show Child’s Play, participating as one of the children who explained clues to contestants.
A few years later, in the summer of 1985, he returned to television as a young celebrity guest on the game show Body Language.
These early appearances helped shape his comfort and confidence in the entertainment industry.
The Role That Defined a Generation
Everything changed in 1985 with The Goonies.
The adventure-comedy followed a group of neighborhood kids on a daring treasure hunt to save their homes.
With Richard Donner directing and Steven Spielberg producing, the film became an instant classic.
Cohen’s portrayal of Chunk brought humor and heart to the ensemble.
The Truffle Shuffle scene became legendary, cementing his place in pop culture history.

A Hidden Challenge on Set
While filming The Goonies, Cohen faced an unexpected personal hurdle.
He was battling chickenpox during production.
Concerned that he might lose the role if the illness became known, he chose to keep it quiet and continued showing up to work.
Sharp-eyed viewers can reportedly see signs of the illness during the Truffle Shuffle scene.
Director Richard Donner later praised Cohen’s authenticity, noting that his performance felt completely natural and genuine.
The Reality of Child Stardom
Landing the role of Chunk was competitive in its own way.
Reflecting on auditions, Cohen once said, “There were basically about four fat kids in town, so every time there was a fat kid role you saw the same people at the audition.”
He added with humor, “It was survival of the fattest.”
The success of The Goonies seemed to promise a long acting career.
However, life had other plans.

When Puberty Changed Everything
As Cohen entered adolescence, his physical transformation altered how casting directors viewed him.
The character of Chunk had been tied closely to his childhood appearance.
He later reflected on that turning point with painful honesty.
”When I hit puberty, it was a career-ender for me. I was transforming from Chunk to hunk, and I couldn’t get roles anymore,” he said.
He described the experience as devastating.
“It was terrible. My first love was acting, but puberty had other ideas. It was a forced retirement. I didn’t give up acting. Acting gave me up.”
Finding a New Direction
Rather than clinging to fading opportunities, Cohen made a decisive shift.
He stepped away from Hollywood and immersed himself in academics and athletics.
He focused on building an identity beyond his childhood fame.
Looking back with humor, he once joked, “I’m pretty good at exercising and watching my diet because I know I could slide back into Chunk. But I am very proud that I was a professional fat person. Anyone can be an amateur, but who can be a pro?”
College Years and Personal Growth
Cohen attended the University of California, Berkeley.
There, he joined the football team and endured the intense rituals of collegiate athletics.
He later admitted that he was frequently knocked down during practices.
He also became known as the school’s mic man, entertaining large crowds who often urged him to perform the Truffle Shuffle.
Eventually, he gave in once, sending the audience into an uproar.
The Mentor Who Changed His Path
Throughout his transition, Richard Donner remained an important figure in Cohen’s life.
The director’s guidance extended far beyond the film set.
When Cohen needed a college recommendation letter, Donner stepped in without hesitation.
Deeply moved by Cohen’s struggles, Donner went even further by covering the cost of his college education.
He also helped him secure behind-the-scenes studio jobs, exposing him to the business side of entertainment.
Cohen once recalled Donner’s blunt advice.
“Hey kid, what do you want to do?”
“I want to be an actor.”
“That’s stupid. You’re not going to be an actor. You’ve got to know about the business.”
Though direct, the message proved transformative.
Academic Achievement and a New Career
Cohen earned a business degree from Berkeley.
He then continued his education at UCLA, where he obtained a law degree.
Instead of returning to acting, he entered the world of entertainment law.
The move allowed him to remain connected to the industry he loved while building a sustainable and respected career.
Building a Reputation in Hollywood
Cohen co-founded Cohen & Gardner LLP.
Over time, he established himself as a significant figure within entertainment law circles.
His work earned recognition, including placement on Variety’s Dealmakers List and The Hollywood Reporter’s Next Gen Executives.
He once explained his motivation clearly.
”I still wanted to contribute to entertainment because I always loved the entertainment industry,” Cohen once told The Journal News.
A Life That Honors the Past
Though his daily work centers on contracts and negotiations, Cohen never distances himself from his childhood fame.
His office reflects both chapters of his life.
He proudly displays a Steven Spielberg-signed E.T. poster reading, “To Jeff (Chunk) Cohen, you are my favorite Goonie.”
A Superman poster from Donner carries another heartfelt inscription: “My man, with you anyone can fly.”
These reminders symbolize both gratitude and continuity.
Clients Who Know Him as Chunk
Cohen’s past often becomes a lighthearted icebreaker in professional settings.
He has acknowledged that clients are amused by his Hollywood origins.
During one interview, he said, “My clients get a kick out of the fact their lawyer is Chunk. They dig it.”
Rather than hindering his credibility, his childhood fame adds a unique dimension to his professional identity.
A Poetic Full-Circle Moment
Perhaps the most remarkable twist in Cohen’s journey came years after The Goonies.
He negotiated the deal for his former co-star Ke Huy Quan in Everything Everywhere All at Once.
The role ultimately earned Quan an Academy Award.
On stage, Quan acknowledged their enduring bond, saying, “My Goonies brother for life.”
The moment symbolized how deeply their shared history continues to resonate.
A Legacy Beyond the Screen
Today, at 51 years old, Jeff Cohen no longer resembles the character audiences first met in 1985.
He jokes that performing the Truffle Shuffle now might require “three martinis” and favorable lighting.
Yet pride in his childhood accomplishment remains strong.
Reflecting on his journey, he said, ”I think it’s crazy. I dig it and I’m very proud of ten-year-old me and that he was able to make such an impact.”
A Rare Hollywood Outcome
The entertainment industry has seen many child stars struggle in adulthood.
Cohen’s path stands out as an exception.
He transitioned successfully from on-screen performer to influential legal advocate.
His humor, resilience, and willingness to reinvent himself shaped a stable and fulfilling life.
Defining Success on His Own Terms
While some fans may wish he had continued acting, his story demonstrates another kind of triumph.
He remained connected to entertainment, just from a different vantage point.
He built a respected career, maintained meaningful relationships, and embraced his past without being confined by it.
From the exuberant child who shouted through doors in The Goonies to a trusted entertainment attorney guiding major deals, Jeff Cohen’s journey reflects growth, adaptation, and determination.
By any measure, it is a success story that extends far beyond the Truffle Shuffle.
