Keeley Karsten Praises 'Malcolm in the Middle' Revival as a 'Physical Comedy Masterclass'

Nearly 20 years after Malcolm in the Middle went off the air, the beloved sitcom returned this month with its revival, Life’s Still Unfair. The iconic cast proved they still have it—and Keeley Karsten is proof.

Karsten joins the franchise as Leah, Malcolm’s daughter, opposite Frankie Muniz, who reprises his role as the titular character. Despite being born after the original series ended, Karsten embraced the role with enthusiasm. “I had never seen the show before I got the part of Leah. It came out before I was born,” she told TheWrap. “What’s funny is, when I had gotten it and told all my friends, everybody knew about it but me. But then I binged the whole show before we started filming and I understood, I got the hype.”

The revival features a returning ensemble cast, including Bryan Cranston as Hal, Justin Berfield as Reese, Christopher Masterson as Francis, Emy Coligado as Dewey, Craig Lamar Traylor as Jamie, David Anthony Higgins as Craig Feldspar, and Jane Kaczmarek as Lois. They are joined by new cast members Vaughan Murrae, Caleb Ellsworth-Clark, and Anthony Timpano.

“They really welcomed me with open arms,” Karsten said. “It was such a comfortable, relaxing, fun environment on set. And it was crazy, because I had binged the show right before, so to see those characters then come to life in front of me—to get to know them and work with them—it was like a physical comedy masterclass. Not only are they really funny on screen, they’re also really funny off screen.”

Karsten also reflected on the dynamic between the returning and new cast members. “The returning cast really was inclusive, but [the new castmembers] all kind of shared the crazy experience of walking into something that had gone on for so long way before us,” she explained. “In that way, I think we were all probably a little bit intimidated. I was really close with Vaughan, so I’m very glad that it was not just me and there was a group of people who also understood… we would do things like walking through the original house tour, and they were all so excited, but we didn’t have that kind of connection to the house yet.”

Leah, like her father Malcolm, breaks the fourth wall by addressing the camera directly. Karsten shared how she adapted to this signature style. “That was just something that I watched him do and kind of eased into as filming started, because it’s all about the timing,” she said. “It was something that Frankie was so used to, just the minute we got on set. The first time I watched him do it, it was like a reflex for him, and it became that later for me.”

Karsten recounted a particularly memorable scene with Muniz. “We had one scene that I filmed with Frankie in a car, and he was doing a ton of improv, going off-the-walls insane. We were laughing a lot that day. I had a really hard time keeping myself together; there are probably not too many takes where I don’t burst out laughing, especially at the end. But that was a really fun day—and to be fair, that was most of my scenes with Frankie.”
