In an exciting revival, the popular sitcom "Malcolm in the Middle" is set to return with a four-episode special on Disney+. However, fans of the original series will experience a significant character shift, as Erik Per Sullivan, who played the beloved Dewey for seven seasons from 2000 to 2006, has chosen not to reprise his role. Replacing him is Fargo actor Caleb Ellsworth-Clark, as reported by US media outlet Variety.

Sullivan, who has long since departed from acting, was confirmed by his former co-star Jane Kaczmarek to be doing well and pursuing academic endeavors, particularly studying Victorian literature at a prestigious American university. Kaczmarek, who played Malcolm's mom Lois, reflects on Sullivan's choice to step away from the spotlight, emphasizing the misconception that fame is universally desirable.

Since his role as Dewey, which he embraced from childhood into his teenage years, Sullivan has maintained a low profile, missing out on several cast reunions. His last credited appearance dates back to the 2010 film "Twelve." As a cherished character in the series, Dewey often found himself at the mercy of his siblings' antics but ultimately grew to show leadership and responsibility.

"Malcolm in the Middle," which premiered in 2000 and concluded in 2006, followed the misadventures of a quirky working-class family led by child prodigy Malcolm, known for his direct commentary to the audience. The series garnered seven Emmy Awards and has been celebrated as a modern classic.

Production for the upcoming revival will take place in Vancouver, Canada, in the coming weeks. The storyline hints at fresh family dynamics, introducing Malcolm's teenage daughter, played by Keeley Karsten. The first episode promises an engaging set of events surrounding the couple Hal and Lois, now celebrating their 40th wedding anniversary.

Other returning cast members include Christopher Masterson as Francis and Justin Berfield as Reese, while new additions like Kiana Madeira and Anthony Timpano promise to enhance the show's legacy. As the excitement builds for this revival, both the cast and fans are eager to see how the story unfolds in this new chapter.
