Mary Tyler Moore, the beloved television icon whose smile lit up American living rooms for decades, carried a secret list of five performers she truly detested—and now, in the final chapter of her extraordinary life, those names have been revealed. The woman who defined grace, independence, and humor on screen held deep, private grievances against some of Hollywood’s most famous faces, according to close friend and confidant Glenn Corbett. Moore, who died in 2017 at age 80, never publicly aired her frustrations during her career, but in her last years she opened up about the co-stars who made her working life a quiet misery.
The list, which Corbett says Moore shared with him in intimate conversations, includes a name that stands above all others: the actor she truly hated more than anyone.
The revelation comes as a shock to millions who grew up watching Moore’s effortless charm on The Dick Van Dyke Show and The Mary Tyler Moore Show. Behind the scenes, however, the atmosphere was far from the warmth she projected on screen. Corbett, who was a trusted presence in Moore’s later years, told this reporter that Moore’s candor was unwavering.
“Mary never pretended every collaboration was easy,” Corbett said. “She had a sharp eye for character, and she didn’t suffer fools gladly.” The list, he confirmed, was a window into the frustrations of a woman who navigated a male-dominated industry with poise but also with a private ledger of slights and irritations.
At the very top of Moore’s list was Rosemary, her co-star on The Dick Van Dyke Show. The on-screen chemistry between Moore’s Laura Petrie and Rosemary’s character was beloved by audiences, but the reality was fraught with tension. Rosemary, an experienced performer with a fiery personality, reportedly saw Moore as an interloper.
“Mary felt overshadowed,” Corbett recalled. “Rosemary never missed a chance to remind everyone who had been in show business longer.” The early seasons of the show were tinged with a competitive uneasiness that never fully dissipated.
Though the tension eased over time, a faint coldness lingered in their professional relationship. Moore, who valued professionalism and preparation, found Rosemary’s need for attention exhausting.
The second name on Moore’s list was James Garner, the ruggedly handsome star known for his easy charm. Moore worked with Garner on a television project that never materialized, but the brief collaboration left a lasting impression. Garner’s cynical humor and casual irreverence clashed with Moore’s serious approach to her craft.
“She didn’t like his habit of making scathing jokes about the industry and its employees,” Corbett said. Garner thrived on spontaneity, while Moore was exacting and detail-oriented. Their temperaments created a subtle but enduring rift.
Moore acknowledged Garner’s talent but found his attitude dismissive.
The third difficult co-star was Ted Knight, who played the bumbling Ted Baxter on The Mary Tyler Moore Show. Knight was adored for his awkward, endearing performance, but off-screen he was moody and sensitive. “Mary once told me that Ted could be incredibly moody,” Corbett said.
Knight’s emotional volatility made the set unpredictable. Moore, who prided herself on maintaining a professional environment, found Knight’s behavior draining. Despite the show’s success, the tension between them was palpable.
Knight’s need for validation often clashed with Moore’s quiet authority.
The fourth name on the list was a performer Moore encountered during a guest appearance on a variety show. The actor, whom Corbett declined to name publicly out of respect for Moore’s wishes, was known for his arrogance and lack of preparation. “Mary was a perfectionist,” Corbett said.
“She couldn’t stand people who didn’t take their work seriously.” The experience was so unpleasant that Moore refused to work with the actor again. She later described the encounter as one of the most frustrating of her career.
The fifth and final name was a producer who Moore felt had undermined her creative vision. While not a performer, this individual wielded significant influence over a project Moore was passionate about. “He treated her like a prop,” Corbett said.
“Mary was never one to be pushed around, but she kept her anger private.” The producer’s condescending attitude left Moore feeling disrespected, and she never forgot the slight.
Moore’s decision to keep this list hidden for so long reflects her commitment to professionalism. She believed that airing grievances publicly would damage the magic of television. “She wanted the audience to believe in the characters,” Corbett said.
“She didn’t want her personal feelings to ruin that.” But in her final years, Moore felt free to speak her truth. The list, Corbett emphasized, was not born of malice but of a desire to be honest about the challenges she faced.
Born on December 29, 1936, in Brooklyn, New York, Moore’s journey from a shy, observant child to a Hollywood legend was marked by resilience. Her parents’ move to Los Angeles when she was eight placed her at the doorstep of the entertainment industry. Dance became her escape, and ballet ignited a fire that would propel her to stardom.
Her first taste of fame came in a series of quirky TV ads, including her role as the dancing elf Happy Hot Point. But it was her portrayal of Laura Petrie on The Dick Van Dyke Show that transformed her into an American icon. Moore broke the mold of the submissive TV wife, wearing Capri pants and delivering sharp, witty lines that resonated with a generation of women.
The Mary Tyler Moore Show, which premiered in 1970, cemented her legacy. As Mary Richards, a single, ambitious producer, Moore embodied the feminist spirit of the era. The show’s iconic opening scene, where she tosses her beret into the Minneapolis sky, became a symbol of female autonomy.
Moore won four Emmys for the role, and the show remains a touchstone of television history. But behind the laughter, Moore battled personal demons. Diagnosed with type 1 diabetes in her early 30s, she became a passionate advocate for research and awareness.
She also faced the devastating loss of her son, Richard, who died in a tragic accident in 1980.
Moore’s personal life was as complex as her career. She married three times, each relationship shaping her emotional landscape. Her first marriage to Richard Meeker ended in divorce, but the couple remained respectful.
Her second marriage to Grant Tinker, a visionary TV executive, was a creative partnership that produced MTM Enterprises and The Mary Tyler Moore Show. The demands of fame and Moore’s health struggles eventually led to their separation in 1981. Her third marriage to Dr.
Robert Levine, a cardiologist, brought stability and love. They remained together until her death.
Moore’s legacy extends far beyond her on-screen achievements. She used her platform to advocate for diabetes research, animal welfare, and humanitarian causes. Her bravery in sharing her personal struggles inspired millions.
Yet, as Corbett’s revelations show, she was also a woman with strong opinions and a sharp memory for slights. The list of five performers she detested is a reminder that even the most beloved icons have private frustrations.
The identity of the actor Moore hated most remains a subject of speculation, but Corbett confirmed that Rosemary was at the top. “Mary truly hated her more than anyone,” he said. The competitive tension between them was a constant source of stress.
Moore’s ability to maintain a professional facade while harboring such feelings is a testament to her discipline. In the end, her list is not a 𝒔𝒄𝒂𝓃𝒹𝒶𝓁 but a humanizing glimpse into the pressures of fame.
As the news breaks, fans are grappling with the complexity of their idol. Moore’s honesty, even in her final years, adds depth to her story. She was not just a smiling face on television; she was a woman who navigated a difficult industry with grace and grit.
Her list of grievances is a footnote to a remarkable life—a life that changed television and inspired generations. Mary Tyler Moore may have hated a few people, but she loved her craft, her causes, and her family with an intensity that will never be forgotten.
