Marta Kristen, the actress who famously portrayed Judy Robinson on the iconic 1960s television series Lost in Space, has broken a decades-long silence about what truly transpired behind the scenes of the beloved sci-fi show. Now 80 years old, Kristen has opened up in a revealing new interview about the tensions, creative frustrations, and deeply personal experiences that shaped her time aboard the Jupiter 2, offering fans an unprecedented look into a world that was anything but weightless. Kristen’s revelations come as a shock to many who grew up watching the Robinson family navigate the perils of deep space. She admits that what viewers saw on screen was often a carefully crafted illusion. When you look at the show, there are times when we are biting our lips from laughing, she recalled. I am trying not to laugh. You know, it was a perfect time for a show like Lost in Space. But beneath the surface of that playful camaraderie lay a story of choices made, opportunities lost, and a character she desperately wanted to be more than just a supporting daughter floating through space. The journey to becoming Judy Robinson was itself extraordinary, a path that began far from the glitz of Hollywood. Born Burgit Analisa Rousanen in Oslo, Norway, Kristen was the daughter of a Finnish mother and a German soldier who was killed during World War II. She was placed in an underground orphanage to avoid being taken into the Nazi Lebensborn program, a state-sponsored initiative designed to breed racially pure children. These early years, marked by war and uncertainty, were a testament to her quiet resilience. In 1949, at just four years old, she was adopted by an American couple from Detroit, renamed Marta Kristen, and began a new life. The transition from war-torn Europe to post-war America was dramatic, but it offered stability and opportunity. She later recalled that her adoptive father’s academic background and her family’s support were instrumental in shaping her outlook. Kristen fell into acting almost by accident. As a teenager, she was discovered in a restaurant by James Harris, the producer of Lolita. That offer went nowhere due to her age, but Harris helped her land an agent. Soon, she started landing roles in prominent television series, including an episode of Alfred Hitchcock Presents opposite her future co-star Billy Mumy. Before auditioning for Lost in Space, Kristen had an impressive resume that also told a more interesting personal story than her screen credits. Born an orphan in hiding, she was adopted into America and eventually grew up to be a promising young actress. In many ways, Judy Robinson seemed to replicate the real-life story of the young actress’s adaptation, courage, and journey into unknown territory. The early revamps of her life, the period of displacement and reinvention, fell under her feet for a truly earthly view to be added to the character she would later portray. Yet even with momentum building, one casting room would leave her stunned. Long before she became Judy Robinson, Kristen came close to landing a role in one of the most beloved musicals of all time, The Sound of Music. She was called in for a screen test and seemed a promising fit for the Von Trapp family. However, to her surprise, she was ultimately turned down, not for a lack of ability, but because producers deemed her too sexy for the wholesome family film. Kristen was just 20 years old at the time, and the label was both confusing and frustrating. I did not think of myself as sexy, she said. I was a Norwegian Midwesterner. For a young actress still trying to establish her identity in Hollywood, being typecast based on appearance rather than talent was a disorienting experience. It revealed early on the double standards of the industry, especially for women, where being attractive could paradoxically close as many doors as it opened. The missed opportunity contained a heavy dose of irony. Kristen’s future Lost in Space co-star, Angela Cartwright, had been cast in The Sound of Music. Kristen took a supporting turn in Lost in Space shortly thereafter. Had she won the part, her career would have undoubtedly languished in the world of musical films. However, she accepted her fate and moved on, landing the role that would define her entire career. Before she ever stepped aboard the Jupiter 2, Kristen faced a difficult decision that could have dramatically altered the course of her career. When Lost in Space was first offered to her, she did not immediately say yes. At the time, she was seriously considering a move to New York to pursue a career in theater, which she described as her first love. Despite the growing momentum in her television career, she was not convinced that a science fiction TV show was the right path for her. Her hesitation lasted nearly two weeks, during which she weighed the appeal of stage acting against the unknown future of a network television series. Friends and colleagues urged her to reconsider, pointing out that such a high-profile role could be life-changing. Eventually, she decided to take the leap, influenced by the belief that Lost in Space might open doors she never imagined. Showrunner Irwin Allen had already set his sights on Kristen for the role of Judy Robinson, and he was not looking for anyone else. Her decision to take on the part was all the more impressive considering she did so knowing that the role would not fulfill her artistic desires. Judy’s role hardly ever saw much use of its presence on the screen or even the character’s development. Kristen wanted more for her character, something that would show her love-hate relationship with literature and Shakespeare, as she was an avid admirer of the text. However, she found meaning in the larger themes of the show and began to appreciate what it offered. In hindsight, she has never regretted making that choice. Although Kristen brought grace and poise to the role of Judy Robinson, she has since revealed that playing the eldest Robinson daughter came with a sense of creative frustration. Despite being part of the core family, her character was often sidelined in favor of the increasingly central figures of Dr. Smith and the robot. Over time, the show’s narrative leaned more heavily into comic relief and campy sci-fi antics, leaving less room for the deeper, more emotionally grounded stories that could have featured Judy. Kristen expressed a specific longing for Judy’s character to reflect her own intellectual and theatrical passions. She had grown up reading and quoting Shakespeare, particularly works like Macbeth, and wished Judy had been written with more complexity and intelligence. In her view, Judy could have been shown as more than just a supporting daughter or love interest. Kristen imagined a version of the character that was more intellectually curious, dramatic, and emotionally rich, someone who brought her own voice to the family dynamic and perhaps even challenged the futuristic challenges they faced. Among the relationships Kristen felt was underdeveloped was that between Judy and Major Don West, played by Mark Goddard. Although hints were dropped toward romance, it never fully entered into the narrative’s focus. Kristen believed this relationship could have really added something to the show, particularly during the socially conscious 1960s. Better writing might have made their relationship a reflection of changing gender roles, youthful romantic spirits in isolation, or a tug-of-war between personal freedom and responsibility. Despite such missed opportunities, Kristen recalls her experience with a sense of appreciation through an honest lens. The truth behind her comments shows that Lost in Space, in many ways, was ahead of its time, but at the same time, it was very much a product of the times, particularly in regard to limiting its female characters. In speaking of these bygone days, she is not bitter. Rather, it is an analysis of the era’s storytelling standards. Even now, in her reflections, she draws attention to what could have been, opening up new perspectives on how fans and creators alike may view an otherwise beloved classic as an incomplete representation of its characters’ full potential. While Lost in Space delivered plenty of light-hearted, campy fun on screen, Kristen recalls that life behind the scenes was filled with genuine emotion, mentorship, and occasionally tension. She described the cast as more than just co-workers. They became a second family. Although they experienced the usual ups and downs that come with working closely on a long-running show, Kristen emphasized that the bonds formed were lasting and deeply meaningful. We had our disagreements like any family, she said, but there was love, respect, and laughter that carried us through. Kristen spoke fondly of the older cast members who became mentors to her during filming. Guy Williams, who played her on-screen father, Professor John Robinson, was a classically trained actor and a former music teacher. She remembered how classical music constantly played from his dressing room, creating a calming presence on set. June Lockhart, who portrayed Maureen Robinson, taught Kristen how to play Scrabble and was described as an extraordinary woman with a rich professional background. Jonathan Harris, who portrayed the mischievous Dr. Smith, left a particularly strong impression. He taught Kristen the value of professionalism. Show up on time, know your lines, and always respect the crew. Kristen was particularly close with Bill Mumy, the young Will Robinson. She said she was the one who first got him into Bob Dylan, and the two were often found singing Dylan songs between takes. Angela Cartwright, who played Penny Robinson, is a very dear friend whom Kristen called one of the sweetest people in the cast. She said her relationship with Mark Goddard was filled with laughter. He could crack her up until she could not breathe. For Kristen, one of her deepest and most cherished reflections was upon meeting Jonathan Harris for the last time before he died in 2002. Harris embraced Kristen after she had done a commercial with him, telling her how lovely she was. This touched her heart. The friendship continued with Harris’s widow, Gertrude, whom Kristen later grew fond of, adopting the dog Gertrude had after she passed. These stories are testimony to the emotional depth that lies beneath those polished TV smiles, creating a cast that genuinely cared for each other. For Kristen, Lost in Space’s true legacy was not really in the space adventures, but rather in the lasting human bonds made around those adventures. Marta Kristen still vividly remembers the moment Lost in Space came to an unexpected halt. She was at home when the call came in. Just a routine afternoon turned life-altering with a few short words. The show had been cancelled. There was no formal farewell, no final episode to wrap up the Robinson’s journey, and no warning signs that the end was near. Kristen was left speechless. For a series that had developed a strong fan base and was doing well in the ratings, the sudden cancellation was not only surprising, but emotionally jarring for the cast. In the aftermath, no one could quite figure out why Lost in Space had been pulled. It was not until much later that Kristen and the rest of the cast discovered the underlying issue, a conflict between series creator Irwin Allen and CBS. According to Kristen, the network had been demanding more scripts than Allen could deliver, reportedly asking for six at a time. Allen, who was juggling multiple projects, was not able to meet the network’s demands. Rather than compromise or fight for the series, he let it go. The decision was largely a logistical one, but it cut short what many believed still had creative life and audience appeal. Another thing that added to the confusion was that Lost in Space continued to perform well with viewers, even generating a loyal following of younger fans. Kristen noted that imaginative stories and a realization of strong themes around family and survival made it popular among children and parents alike. The production itself also invested massively in visual effects and making elaborate sets, making this quite an expensive business, most likely yet another reason for CBS pulling the plug. Even after the disappointment passed, Kristen would later reflect on the legacy of the show with a certain gratitude. Although she would have liked to have a proper sendoff, she was proud of what they produced together. She was particularly moved by the fact that younger generations now continue to discover Lost in Space well past the time it aired. It had sent the message home that while there was no closure with the cancellation of the show, the quality remained, and that was comforting to Kristen. It still surprises me, she recalled, that people even today, with all the modern gimmicks, can remember our simple little show. Though Lost in Space came to an unexpected end, its influence on Kristen’s life proved to be lasting and deeply personal. She spoke with heartfelt honesty about what the series gave her beyond fame, a true sense of belonging. For a woman who had started life in an orphanage in Norway, the experience of joining a tight-knit cast and working closely for three seasons created something more profound than a job. It created a family. The ensemble nature of the show and the long hours on set fostered a spirit of collaboration and emotional closeness that Kristen would treasure for decades. Kristen described learning valuable lessons from her fellow cast members, particularly about professionalism, respect, and dedication. Jonathan Harris stood out as someone who taught her the importance of showing up on time, knowing your lines, and honoring the work of everyone on set. These lessons helped her develop a strong work ethic and a deeper appreciation for the collaborative nature of television. The cast, while occasionally having disagreements, operated with mutual respect and affection, and this environment helped Kristen grow not just as an actress, but as a person. She forged relationships on the set of the show that endured even after it had long left the air. She remained close friends with some co-stars, including Bill Mumy and Angela Cartwright, as the three would eventually collaborate decades later on the book Lost and Found in Space 2. Kristen also had a lifelong friendship with Gertrude, Jonathan Harris’s widow, and adopted her dog after Gertrude died, creating an emotionally charged connection that spoke to how much Lost in Space had entered into her personal life. In the end, Kristen would say that Lost in Space gave her more than career recognition. It gave her a space to be seen, valued, and connected. The cameras gave her visibility, but also a home away from home while she was still giving herself a foothold in Hollywood. I gained a sense of an ensemble, she said, a sense of what it is like to work together. For Marta Kristen, the true legacy of the show was not its fame, but the friends she made and the feeling of family that stayed with her long after the cameras stopped rolling. Decades after Lost in Space ended, Kristen reunited with her longtime co-stars Bill Mumy and Angela Cartwright for a special project that reignited memories and brought their shared history to life. Together, they published Lost and Found in Space 2 Blastoff into the Expanded Edition, a richly illustrated memoir that featured nearly 1,000 behind-the-scenes photographs, including more than 600 never-before-seen images. The book was not just a nostalgic look back. It was a personal and emotional journey through their years on set, one that unearthed long-forgotten stories and emotions for Kristen. Many of the photos had been recently discovered and hand-selected by Kristen, Mumy, and Cartwright themselves, making the book deeply personal and unique. For Kristen, flipping through the images was like opening a time capsule. She recalled moments of laughter, long filming days, and the familial bonds that developed among the cast. For her, this book was not merely an autobiography, but an ode to memory, friendship, and strength. It was a revisit to times that were greatly positive and that had an impact on her life while incorporating that experience into the lives of fans both new and old. Doing so would bring healing and pride to reaffirm that the relationships forged in a fictitious world of a spaceship were real, lasting, and truly human. Rediscovering those images and stories, Marta Kristen found herself not just coming back to the past, but also to understanding what the journey that started so many years ago meant. … Read more
