The Malcolm in the Middle cast looks so different now: from Bryan Cranston to Frankie Muniz

Frankie Muniz, who portrayed Malcolm, has stayed strong in the entertainment industry and has continued acting in several movies featuring Renner, Half Baked: Totally High, and The Black String. He has also taken part in TV series including, The Rookie, New Amsterdam, and Awkwafina Is Nora from Queens.

Bryan Cranston, who played Frankie’s father in the sitcom, Hal, went on to become extremely famous for his role as Walter White in Breaking Bad, which concluded in 2013. Since then, he has continued acting in movies such as El Camino, and in TV series including It's Always Sunny in Philadelphia.

Jane Kaczmarek, who plays the mother and wife in the family, Lois Wilkerson, has remained steady in her acting career as well. Her most recent acting credit was in 2024, and includes the short film, And Now I Lay Me Down, and the TV series, The Changeling, which came out in 2023.

Christopher Masterson, who portrays one of the brothers, Francis, is coming back on the cast and his last acting roles were in 2019, with the movies, Beneath the Leaves and I'd Like to Be Alone Now.

Justin Berfield, who portrayed another one of Malcolm's brothers in the series, Reese, is also returning to the revival, however, his last acting gig was in 2010 in the TV series, Sons of Tuscon, therefore he is coming back to acting after a hiatus.

Unfortunately class clown Erik Per Sullivan who was the brothers’ youngest sibling, named Dewey, will not be returning. It seems the young performer decided to conclude his acting career in 2010, with his last role being Timmy in the movie Twelve.

Instead of acting, Erik has dedicated all his focus to studying Victorian literature, per Distractify. He was also the recipient of the Literary and Historical Society of the University College Dublin’s James Joyce Award.

Caleb Ellsworth Clark will be replacing Erik for the charming and hilarious role of Dewey.
