'Malcolm in the Middle' fans are celebrating the show's comeback, though many are left wondering about the absence of Dewey, played by Erik Per Sullivan. The young actor, who traded his acting career for studies at 14, has reportedly passed on significant offers to return.

The family comedy will return for a limited, four-episode run on Disney+ with original cast members Frankie Muniz, Bryan Cranston and Jane Kaczmarek on board to reprise their roles as Malcolm, and his parents Hal and Lois, respectively.
