Malcolm in the Middle star Frankie Muniz, 39, has shared a nostalgic behind-the-scenes reunion with his TV brothers. Muniz posted the image on Thursday with his co-stars, Justin Berfield, who played Reese, and Christopher Masterson, who played Francis, ahead of the series revival. Muniz, who starred as the titular Malcolm in the series that ran from 2000 to 2006, smiled next to Berfield, 39, and Masterson, 45. “I was told not to post this yet, but then I listened to this song,” Muniz wrote in the caption, which he posted on Instagram with the Malcolm theme tune—“Boss of Me” by They Might Be Giants. “I’m just too excited for y’all to see the new episodes and I miss my brothers.” The reboot, which is set to debut on Disney+, is slated to be released in 2026. The four-episode miniseries announced in December 2024 is titled Malcolm in the Middle: Life’s Still Unfair. The brothers’ on-screen parents, Bryan Cranston and Jane Kaczmarek, will also make appearances. The actor who played the youngest brother Dewey, Erik Per Sullivan, will not be returning as he pursues a master’s at Harvard University, according to Cranston, 69. The character will be played by Caleb Ellsworth-Clark instead.
