Malcolm’s younger brother will look a lot different in the Malcolm in the Middle revival.

Disney+ has confirmed that original series stars Christopher Masterson (Francis) and Justin Berfield (Reese) will reprise their roles in the Disney+ sequel series, alongside fellow returning regulars Frankie Muniz (Malcolm), Jane Kaczmarek (Lois) and Bryan Cranston (Hal).

However, Erik Per Sullivan, who played Dewey on Fox’s early-aughts sitcom, will not be back; he’ll be succeeded in the role by Caleb Ellsworth-Clark (Wynonna Earp), as seen below:

WHY THE RECAST?

TV mom Kaczmarek explained to Malcolm France last year that Per Sullivan “started [Malcolm] at 7, he ended at [age] 14,” and “wasn’t into acting, at all.” Per Sullivan attends a “very, very prestigious American university,” she added, where he is doing graduate work related to Victorian literature.

WHO ELSE IS NEW?

Rounding out the revival cast are Anthony Timpano as Malcolm’s brother Jamie, Vaughan Murrae (The Way Home) as youngest sibling Kelly, Kiana Madeira (Trinkets) as Malcolm’s girlfriend Tristan, and Keeley Karsten (The Fabelmans) as Malcolm’s daughter Leah.

Malcolm in the Middle originally aired for seven seasons on Fox, from 2000 to 2006. The show won seven Primetime Emmy Awards for writing and directing over the course of its run, as well as two wins for guest star Cloris Leachman. It received 26 additional nominations, with Kaczmarek and Cranston regularly earning nods for their performances.

The Malcolm in the Middle revival, which does not yet have a premiere date, will consist of four episodes. Are you looking forward to seeing the whole family (and Dewey 2.0) together again?
