5 Shocking Reasons Why 'Dewey' From Malcolm In The Middle Disappeared From Hollywood (And Where He Is Now In 2025)
The character of Dewey from Malcolm in the Middle, the youngest and arguably most philosophical of the Wilkerson brothers, was a fan favorite known for his deadpan genius and bizarre, often tragicomic, life. However, unlike his on-screen brothers, the actor who played him, Erik Per Sullivan, chose a path of extreme privacy almost immediately after the show concluded, sparking years of rumors and intense curiosity among fans. As of December 2025, the mystery surrounding his life continues to fascinate, especially with the persistent news of a potential series revival.
The most current and definitive update on the former child star is that he has completely stepped away from the spotlight, choosing a quiet, academic life over Hollywood fame. His decision to pursue a career outside of acting is so firm that he will not be reprising his iconic role in the rumored Malcolm in the Middle revival, a decision that speaks volumes about his commitment to a normal, private existence. This is the true story of Erik Per Sullivan's remarkable transition.

The Great Disappearance: Why Erik Per Sullivan Left Hollywood
After Malcolm in the Middle concluded in 2006, Erik Per Sullivan’s public appearances dwindled rapidly. By 2010, after his role in the film Twelve, he had effectively vanished from the entertainment industry and public eye. This abrupt departure fueled speculation, but the reality is a simple, deliberate choice for a private life.
1. A Firm Decision to Step Away from the Spotlight
Unlike many child actors who attempt to transition into adult roles, Sullivan made a clean break. He has intentionally stayed away from all forms of social media, public events, and the entertainment industry entirely. This desire for a "normal life" appears to be the primary motivation behind his disappearance. He was rarely, if ever, seen at cast reunions or public events for the show, a clear signal of his commitment to his privacy.
2. Pursuing a High-Level Academic Career
The most compelling reason for his retirement is his dedication to higher education and an academic career. After leaving acting, Sullivan briefly attended the University of Southern California (USC). More recently, reports from those close to the cast, including co-star Bryan Cranston, have suggested he is pursuing graduate studies at a highly prestigious institution, with some unconfirmed reports mentioning Harvard. Other accounts, including one from Jane Kaczmarek (Lois), suggest he is living a normal life as a biology student, focused on science and academia.
This focus on intellectual pursuits aligns with the character of Dewey, who was often shown to be a gifted individual, finding solace and complexity in his own world.
3. Request for Extreme Privacy
The mystery surrounding his current university and field of study is not accidental. According to reports, Erik Per Sullivan has specifically asked his former castmates and others to respect his privacy and keep the details of his current life quiet. This request is a rare move in the age of constant celebrity exposure, highlighting his genuine desire to live outside the public domain. His co-stars, including Bryan Cranston and Jane Kaczmarek, have consistently respected this wish, only confirming that he is happy and well.
The Malcolm in the Middle Revival: Why Dewey Won't Return
The news of a potential Malcolm in the Middle revival, often spearheaded by Bryan Cranston (Hal), has been a hot topic for years. Fans universally hoped to see the entire Wilkerson family—Hal, Lois, Francis, Reese, Malcolm, and Dewey—return. However, Erik Per Sullivan’s commitment to his post-Hollywood life has led to a major casting update that shocked the fanbase.
4. The Recasting of Dewey and Jamie
In a major development, it was announced that Erik Per Sullivan would not be returning to his role. Instead, the character of Dewey would be recast, with actor Caleb Ellsworth-Clark reportedly set to take over the role in the new series. This decision is the clearest indication yet that Sullivan’s acting career is permanently behind him. The show's youngest brother, Jamie, is also expected to be recast, played by Anthony Timpano.
The fact that the producers and cast are moving forward with a recast for such a pivotal character underscores how firm Sullivan is in his decision to remain a private citizen. While fans may be disappointed, the move respects his chosen path.
5. A Complete Pivot to a Non-Creative Career
Erik Per Sullivan’s life is a fascinating case study in a child star who successfully navigated the pitfalls of early fame by simply walking away. His pivot was not to music, directing, or other creative endeavors, but to a serious academic path, which is highly unusual for a former actor. This suggests a deep, personal passion for his chosen field—be it biology, literature (as one report mentioned his love for Charles Dickens), or another science—that far outweighs the allure of a lucrative acting comeback.
In a world where every former celebrity is on social media, Erik Per Sullivan's deliberate silence and success in maintaining his privacy make him one of the most intriguing "where are they now" stories in Hollywood history. He is a testament to the fact that sometimes, the greatest role a former star can take is that of a normal, successful private citizen.
