Which ‘Malcolm in the Middle’ Roles Were Recast in the Revival Following Cast Exits?

Malcolm in the Middle faced several recastings in its four-part revival.

After Hulu picked up a revival series for Malcolm in the Middle, it was confirmed that Erik Per Sullivan would be recast, with Caleb Ellsworth-Clark taking over the role of Dewey.

The rest of the cast — including Frankie Muniz, Bryan Cranston, Jane Kaczmarek, Christopher Masterson and Justin Berfield — reprised their respective characters. In addition to the main cast, Kiana Madeira, Anthony Timpano, Vaughan Murrae and Keeley Karsten were cast in key roles as well.

“25 years since we premiered Malcolm in the Middle. I’m so excited… that I may have peed just a little bit,” Cranston, 70, and Kaczmarek said in a December 2024 announcement post. “What a delight that I get to yell at that kid again! We’re very, very excited about coming back together and seeing what this family has been up to.”

The revival was written by Linwood Boomer, who created the original series. It chronicled Malcolm (Muniz) and his daughter as they are “drawn into the family’s chaos when Hal (Cranston) and Lois (Kaczmarek) demand his presence for their 40th wedding anniversary party,” according to a press release.

It was later revealed that Per Sullivan got a hefty offer to return for the Malcolm in the Middle revival, but he ultimately said no.

Per Sullivan’s onscreen mom, Kaczmarek, was asked about his absence from the upcoming four-part special, telling The Guardian in April 2026 that the retired actor is “studying Dickens and is an incredible student.”

“They offered him buckets of money to come back, and he just said, ‘No, thank you,’” she added.

Kaczmarek previously defended Per Sullivan’s decision to stay out of the spotlight.

“I admire it because so many people think being in show business is the greatest thing in the world. It’s not for everyone,” she said in a 2024 interview about how Per Sullivan is a student at “a very prestigious American university.”
