For many people who grew up in the 1980s, “The Goonies” remains one of the most memorable adventure films of the era. Among its ensemble of young actors, Jeff Cohen became an instant fan favorite for his portrayal of Chunk—a character known for humor, enthusiasm, and an unforgettable sense of charm. Decades later, Cohen’s transformation from child actor to respected entertainment lawyer stands as one of Hollywood’s most inspiring career evolutions.
Early Life and Introduction to Acting
Jeffrey Bertan McMahon, known professionally as Jeff Cohen, was born on June 25, 1974, in Los Angeles. He later adopted the surname Cohen, honoring his mother’s maiden name. According to verified interviews and public records, he developed an interest in performing at a young age. Before landing his most iconic role, he appeared on the CBS game show Child’s Play from 1982 to 1983, where children helped contestants guess words through descriptions. In 1985, he returned to television as a young guest on the game show Body Language.
As his confidence on camera grew, Cohen continued auditioning for film and television roles, eventually earning the opportunity that would define his early career.
Breakthrough with “The Goonies”
Cohen’s breakout role came with the 1985 Warner Bros. film The Goonies, directed by Richard Donner and produced by Steven Spielberg. The movie told the story of a group of friends searching for long-lost treasure in hopes of saving their homes. Cohen’s portrayal of Chunk quickly became one of the film’s standout performances, remembered for comedic timing and genuine personality.
Several reputable sources, including Warner Bros. commentary tracks and interviews with the cast, have noted a unique behind-the-scenes detail: Cohen was battling chickenpox during the early days of filming. Concerned that he might lose the role, he continued performing. Fans who rewatch the movie sometimes point out that small spots are visible in certain scenes.
Director Richard Donner often praised Cohen’s natural acting ability, noting that he brought authenticity and spontaneity to the character. Cohen, reflecting on that time in various interviews, said the experience shaped his understanding of teamwork, storytelling, and the entertainment industry.
Transition Out of Child Acting
Following The Goonies, Cohen hoped to continue acting. However, like many child actors, he faced challenges as he grew older. In interviews with outlets such as The Daily Mail and The Journal News, Cohen explained that roles became more difficult to secure as he transitioned through adolescence. With fewer opportunities available, he made the decision to shift away from acting and redirect his energy toward education and athletics.
Cohen attended the University of California, Berkeley, where he became involved in campus life, including the football program. He later earned a business degree, an experience he has credited with expanding his understanding of how the entertainment industry operates behind the scenes.
Support from Director Richard Donner
One of the most meaningful professional relationships to come out of The Goonies was Cohen’s connection with director Richard Donner. Multiple verified interviews describe how Donner admired Cohen’s dedication and later supported his academic and professional pursuits. When Cohen approached him for a college recommendation, Donner provided a letter and offered additional guidance.
According to Cohen, Donner also encouraged him to consider careers beyond acting. This advice played a significant role in shaping his future and helped him discover his talent for leadership, communication, and business.
Becoming a Respected Entertainment Attorney

Cohen has represented a wide range of professionals in film, television, and media, negotiating contracts and advocating for talent. His background as a performer gives him unique insight into the experiences of actors and creators, something clients frequently highlight as a strength.
