The late Robert Carradine, who passed away on February 23, 2026, at the age of 71, is being remembered by fans worldwide for his beloved role as Sam McGuire, the well-meaning and slightly goofy father on the Disney Channel hit Lizzie McGuire. But long before he was helping Hilary Duff navigate the ups and downs of junior high, Carradine built a decades-long career filled with eclectic roles, including a memorable guest spot in an underrated NBC sci-fi series that has since become a cult classic.
While tributes pour in from his Lizzie McGuire family and fans of the Revenge of the Nerds franchise, a deeper look at Carradine’s filmography reveals a versatile actor who popped up in some of the most interesting television projects of the 80s and 90s. One such role was in the eerie and small-town horror series The Tommyknockers.
Robert Carradine’s Role in The Tommyknockers
Based on the massive 1987 novel by Stephen King, The Tommyknockers was a television miniseries that aired on ABC in 1993. The story follows the residents of Haven, Maine, who slowly discover a mysterious alien object buried in the woods. As they unearth it, the object begins to exert a strange influence over the town, granting the residents bursts of creative and inventive energy while simultaneously turning them into cold, alien-like beings.
In this sprawling sci-fi horror story, Robert Carradine took on the role of Bryant Brown, the town’s alcoholic poet. Bryant is one of the first characters to be significantly transformed by the Tommyknockers’ influence. The alien force removes his addiction and grants him a burst of literary genius, but at the cost of his humanity .
Carradine’s performance was a standout in the miniseries. He brought a tragic vulnerability to Bryant, portraying a man whose deepest flaws are “cured” by an inhuman force, leaving him empty and monstrous. For fans of Stephen King adaptations, The Tommyknockers holds a special, if somewhat flawed, place in history, and Carradine’s role is a key part of its cult appeal.
This guest spot came at a busy time in Carradine’s career. During the early 90s, he was juggling roles in the Revenge of the Nerds sequels and appearing in a wide range of television shows, from Lois & Clark: The New Adventures of Superman to the Western series Kung Fu: The Legend Continues, which starred his half-brother, the late David Carradine .
The Sci-Fi Role That Fans Remember
For many who grew up watching syndicated television in the 90s, The Tommyknockers was a defining slice of sci-fi horror. While the miniseries received mixed reviews upon its release—critics often pointed to its pacing and special effects—it has gained a dedicated following over the years.
Robert Carradine’s involvement added a layer of credibility and familiarity. By 1993, he was already a well-known face. He had transitioned from gritty 70s films like Martin Scorsese’s Mean Streets and the John Wayne Western The Cowboys to the mainstream success of Revenge of the Nerds . Seeing him in a darker, more dramatic role within a Stephen King story showed his range as a performer.
For fans who only know him as the supportive dad from Lizzie McGuire, going back to watch The Tommyknockers can be a surprising experience. It is a reminder that Carradine had a long and varied career before he ever stepped onto the Disney Channel set.
From Cult Classics to Disney Dad
Robert Carradine was born into Hollywood royalty. As a member of the legendary Carradine acting family—son of John Carradine and half-brother to David and Keith Carradine—acting was in his blood. He made his screen debut in 1971 and quickly built a resume that any actor would envy.
Before the 90s sci-fi gigs and the 2000s family-friendly fame, Carradine was a staple of 1970s and 1980s cinema. He starred alongside his brothers in the Western The Long Riders (1980), where they played the Younger brothers, and appeared in Samuel Fuller’s war epic The Big Red One (1980) . His role as Lewis Skolnick in Revenge of the Nerds (1984) made him a star, turning the character into a pop culture icon for underdogs everywhere.
In between starring in the Nerds sequels, Carradine continued to work steadily in television. His guest appearance in The Tommyknockers was just one of many. He also showed up in procedural dramas like ER and NYPD Blue, proving he could fit into any genre .
The Legacy of a Beloved Actor
When Robert Carradine joined the cast of Lizzie McGuire in 2001, a whole new generation of viewers fell in love with him. As Sam McGuire, he was the dad who tried his best, often with clumsy results. His chemistry with Hilary Duff and Jake Thomas created a TV family that felt real and relatable.
Following the news of his passing, his on-screen family shared their grief. Hilary Duff posted a heartfelt tribute on Instagram, saying, “There was so much warmth in the McGuire family and I always felt so cared for by my on-screen parents. I’ll be forever grateful for that” . Jake Thomas, who played his son Matt, also shared memories, calling Carradine “one of the coolest guys you could ever meet” .
His real-life family also paid tribute. His daughter, actress Ever Carradine, shared that her father raised her as a single parent, providing her with stability. His niece, Martha Plimpton, called him the “best” of the Carradine brothers, praising his inherent kindness .
Carradine’s family revealed that he had struggled with Bipolar Disorder for nearly two decades. They hope his journey can help address the stigma surrounding mental illness .
