A "Malcolm in the Middle" revival is set for Disney+, but one of the primary roles on the series will be filled by a different actor after the original star left Hollywood.

The full cast for the Disney+ revival has been confirmed, with one character getting recast, while more info about the youngest children -- one of whom is non-binary -- is revealed.

Christopher Masterson and Justin Berfield have joined the four-episode revival alongside their original series co-stars Frankie Muniz, Bryan Cranston and Jane Kaczmarek. Caleb Ellsworth-Clark, Anthony Timpano, Vaughan Murrae and Keeley Karsten have also signed on to the series.
