There are few movie characters as instantly recognizable as Chunk from The Goonies. With his unforgettable Hawaiian shirt, lovable personality, and the famous “Truffle Shuffle,” Jeff Cohen became one of the most memorable child actors of the 1980s.
Many fans assumed he would continue acting for decades. Instead, his journey took an unexpected turn. As he grew older, Hollywood opportunities faded, prompting him to reinvent himself in an entirely different career. Today, Jeff Cohen is not only remembered for an iconic film role but is also respected as a successful entertainment attorney whose work continues to shape the film industry behind the scenes.
His story is one of resilience, adaptability, and discovering that success can take many forms.
The Boy Who Became Chunk
Jeffrey Bertan McMahon, better known professionally as Jeff Cohen, was born on June 25, 1974, in Los Angeles, California.
From an early age, he showed an interest in performing. After his parents separated during childhood, he adopted his mother’s maiden name, Cohen, as his professional surname.
Before becoming famous, Jeff appeared in several television programs, including the CBS game show Child’s Play, where children helped contestants solve word puzzles.
These early appearances gave him valuable on-camera experience, preparing him for the opportunity that would change his life forever.
Landing the Role of a Lifetime
In 1985, Jeff Cohen was cast as Lawrence “Chunk” Cohen in The Goonies, an adventure film directed by Richard Donner and produced by Steven Spielberg.
The movie follows a group of neighborhood friends searching for hidden pirate treasure in hopes of saving their homes.
Although every member of the cast became memorable, Chunk quickly emerged as one of the audience favorites thanks to his humor, honesty, and infectious enthusiasm.
One of the film’s most famous scenes—the Truffle Shuffle—has remained a beloved piece of pop culture for decades.
Interestingly, Cohen later joked that auditions for larger child actors were highly competitive because there were so few opportunities.
His natural comedic timing helped him stand out from the crowd.
Behind the Scenes of The Goonies
Fans have learned many fascinating stories about the making of The Goonies over the years.
One surprising detail is that Jeff Cohen reportedly developed chickenpox during filming. Concerned that he might lose the role, he continued working while trying to avoid disrupting production.
Director Richard Donner often praised Cohen’s authentic personality, saying his performances felt genuine because he simply embraced who he was.
The strong friendships formed during filming have also lasted decades. Many cast members continue to reunite for anniversaries, conventions, and interviews celebrating the film’s enduring popularity.
When Hollywood Changed
After The Goonies, Jeff Cohen appeared in several television shows and family films.
However, childhood success brought an unexpected challenge.
As he entered adolescence, his appearance changed dramatically. Hollywood had often cast him because he fit a particular character type, but those roles disappeared as he matured.
Years later, Cohen reflected humorously on this transition by saying that he didn’t quit acting—acting “gave up” on him.
Rather than allowing disappointment to define him, he focused on education and began exploring entirely new possibilities.
His experience illustrates one of the realities many child performers face: careers often evolve in unexpected ways as they grow older.
Finding a New Purpose Through Education
Leaving acting behind was not the end of Jeff Cohen’s story.
Instead, it became the beginning of another chapter.
He enrolled at the University of California, Berkeley, where he earned a business degree. During college, he participated in athletics and embraced campus life, developing confidence outside the entertainment world.
After graduation, he attended the UCLA School of Law.
There, he discovered a profession that combined his understanding of Hollywood with legal expertise.
His years as an actor gave him unique insight into the challenges performers face when negotiating contracts and protecting their careers.
Richard Donner’s Lasting Influence
One of the most meaningful relationships in Jeff Cohen’s career remained his friendship with director Richard Donner.
Donner encouraged Cohen to learn the business side of entertainment rather than relying solely on acting opportunities.
According to Cohen, Donner believed understanding how the industry worked would create long-term opportunities.
That advice proved invaluable.
Donner also supported Cohen academically, writing recommendation letters and helping open doors within the entertainment industry.
Their mentor-student relationship became an inspiring example of how experienced professionals can positively influence young talent beyond a single project.
Becoming One of Hollywood’s Entertainment Lawyers
Today, Jeff Cohen is recognized as one of Hollywood’s respected entertainment attorneys.
He co-founded Cohen Gardner LLP, a law firm specializing in entertainment, media, and intellectual property matters.
Instead of appearing in front of cameras, he now works behind the scenes helping actors, producers, writers, and filmmakers negotiate contracts and navigate the entertainment business.
Industry publications have recognized his professional achievements, highlighting his expertise in complex entertainment deals.
His unique perspective—as someone who experienced childhood fame firsthand—helps him understand the needs of creative professionals.

Helping Fellow Stars Succeed
One especially meaningful moment in Cohen’s legal career involved his former Goonies co-star, Ke Huy Quan.
Years after they worked together as children, Cohen represented Quan during important contract negotiations connected to Everything Everywhere All at Once.
Quan later won the Academy Award for Best Supporting Actor.
During his acceptance speeches, Quan publicly thanked Cohen, affectionately referring to him as his “Goonies brother for life.”
The moment highlighted the enduring friendships created during the making of the classic adventure film.
It also demonstrated how Cohen continues contributing to Hollywood in significant ways, even if audiences no longer see him on screen.
Life Beyond Fame
Unlike many former child actors, Jeff Cohen has largely maintained a private and balanced personal life.
Rather than pursuing celebrity status, he has focused on building a stable career and long-term professional reputation.
He occasionally participates in interviews, fan conventions, and anniversary celebrations for The Goonies, where audiences continue to celebrate his contribution to one of the most beloved family adventure films ever made.
Fans often express surprise at how different he looks today.
Cohen himself has approached that reaction with humor, recognizing that personal growth naturally changes everyone’s appearance over time.
Why The Goonies Still Matters
Released in 1985, The Goonies remains one of the defining family adventure films of its generation.
