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 (Frankie), Jane Kaczmarek (Lois) and Bryan Cranston (Hal). However, Erik Per Sullivan, who played Dewey on the Fox sitcom, won’t be back; he’ll be succeeded in the role by Caleb Ellsworth-Clark (Wynonna Earp). The Malcolm in the Middle revival, which does not yet have a premiere date, will consist of four episodes.
