This decision makes his post-Hollywood life one of the most compelling stories among former child actors.

Following the end of Malcolm in the Middle in 2006, Sullivan took on only a handful of sporadic roles, with his last known credit being in the 2010 film Twelve.

Instead of auditioning, Sullivan pursued higher education. Reports from former co-stars Bryan Cranston and Frankie Muniz confirm that he is deeply invested in his studies. Cranston, who played the family patriarch Hal, revealed that Sullivan is pursuing a Master's degree at a highly prestigious university, with multiple sources pointing to Harvard University.

His field of study is reportedly Victorian Literature, a far cry from the slapstick comedy of the Wilkerson household. This intellectual pursuit aligns perfectly with the character of Dewey, who was often depicted as the most thoughtful, artistic, and philosophical member of the family, despite being constantly overlooked. His choice highlights a genuine desire for intellectual fulfillment over the demands of celebrity.

7 Shocking Facts About Erik Per Sullivan's Current Life and Career Decisions

Erik Per Sullivan’s post-fame life is shrouded in mystery, which only fuels the public's fascination. These seven facts offer the clearest picture of what the former Dewey is doing today and why he has chosen to remain out of the spotlight.

1. He Is the Only Major Cast Member Skipping the Revival

The news of a Malcolm in the Middle reboot has been met with excitement, but it comes with a major caveat: Erik Per Sullivan will not be reprising his role as Dewey. Bryan Cranston and Frankie Muniz (Malcolm) have both publicly confirmed his absence. Cranston explained that Sullivan simply retired from acting and chose not to return, prioritizing his education and private life. This makes him the only member of the core Wilkerson family—Lois (Jane Kaczmarek), Hal (Bryan Cranston), Reese (Justin Berfield), Malcolm (Frankie Muniz), and Francis (Christopher Masterson)—to decline the reunion.

2. The Role of Dewey Will Be Recast

Due to Sullivan's firm decision to remain retired, the role of Dewey Wilkerson in the upcoming revival will be played by a new actor. The new series is reportedly moving forward with actor Caleb Ellsworth-Clark stepping into the iconic role. This recasting, while necessary for the show's narrative, underscores the finality of Sullivan's departure from Hollywood.

3. He Was Spotted in Boston After Years of Silence

For nearly two decades, Erik Per Sullivan has been absent from public events, social media, and red carpets, leading to rumors and speculation. However, in recent years, he has been seen out and about, particularly in the Boston area, which aligns with the reports of his academic pursuits in the Northeast. These rare sightings confirm that he is "well," as noted by Frankie Muniz, and simply enjoying a non-celebrity existence.

4. His Last Known Role Was a Cameo in a Star-Studded Film

Sullivan's final acting credit, before his official retirement from the industry, was a small role as "Timmy" in the 2010 film Twelve. Directed by Joel Schumacher, the movie featured a cast of young Hollywood stars, including Chace Crawford and Emma Roberts. His choice to step away after this role solidified his transition out of the industry at the age of 19.

5. He Was a Voice Actor in a Pixar Classic

Beyond his work as Dewey, one of Sullivan’s most recognizable roles was a voice-over part in a major animated film. He provided the voice of Sheldon, the seahorse with a chronic allergy, in the 2003 Pixar hit Finding Nemo. This role, alongside his appearance in the two-time Academy Award-winning film The Cider House Rules (1999), shows his involvement in high-profile projects from a very young age.

6. He is a Musically Gifted Entity

The character of Dewey was often seen playing the piano, a trait that mirrored Erik Per Sullivan’s real-life talents. As a child, he was known to study and play both the piano and the alto saxophone. This musicality was skillfully woven into the fabric of the Dewey character, adding to his unique, introspective personality that contrasted with the chaos of his brothers, Malcolm and Reese.

7. The Cast Respects His Extreme Privacy

Despite the persistent fan questions, the entire Malcolm in the Middle cast, including Frankie Muniz and Jane Kaczmarek (Lois), has consistently respected Erik Per Sullivan's decision to maintain his privacy. They have only offered brief, reassuring updates that he is doing well and is happy living his life outside of the public eye. This collective respect speaks volumes about the bond they share and their understanding of his choice to step away from the pressures of child stardom.

The Enduring Legacy of Dewey Wilkerson

While Erik Per Sullivan may have retired, the character of Dewey Wilkerson continues to resonate with audiences. Dewey’s journey—from the tormented, often-ignored little brother to the surprisingly wise and insightful philosopher—made him a fan favorite. His famous quotes, such as the philosophical musings on life's unfairness or his deadpan delivery, cemented his status as the "heart and soul" of the show.

The fact that he has traded a life of celebrity for a life of intellectual pursuit, reportedly studying complex subjects like Victorian Literature, is a fitting epilogue for a character who was always smarter and more profound than anyone gave him credit for. Erik Per Sullivan’s story is a powerful reminder that life after a hit sitcom can be anything but typical, and for him, a quiet life in academia is the ultimate happy ending.
