The Malcolm in the Middle revival is set to begin filming in Vancouver in the next few weeks, with one major change from the cast of the original series.<br /><br />Frankie Muniz is set to reprise the title role, with Bryan Cranston and Jane Kaczmarek also returning as his parents.<br /><br />However, Variety reports that Erik Per Sullivan, who played youngest brother Dewey in the beloved family sitcom, will not return. His role will be filled by Fargo actor Caleb Ellsworth-Clark.<br /><br />Christopher Masterson, who played oldest brother Francis, and Justin Berfield, who played Reese, will both return.<br /><br />Sullivan’s absence appears to be because of his decision to move away from acting as a career. Last year, Kaczmarek spoke to fan site Malcolm France about Sullivan and said: “He’s well, he’s very, very well… He did Malcolm for seven years, he started at seven, he ended at 14. He wasn’t interested in acting, at all.
