In September 1970, millions of Americans tuned in to watch two of the most famous faces of their era share a television screen. Richard Burton, the Welsh actor whose booming Shakespearean voice had made him an international star, was appearing on Here’s Lucy, the sitcom built around Lucille Ball, the red-haired queen of comedy who had redefined television with I Love Lucy two decades earlier. The episode was promoted as a triumph of casting, a collision of high art and popular entertainment that promised ratings gold. Behind the cameras, however, it was something else entirely.

Burton would later describe Ball in terms so harsh that his own published diaries read like an indictment. By 1970, Burton was at the height of his fame and notoriety. He and Elizabeth Taylor, married to each other twice, formed Hollywood’s most glamorous and scandal-ridden power couple. Burton was known for his intensity as a performer and for a personal life that kept tabloids in business.

Lucille Ball, meanwhile, had long since secured her place in television history. After conquering the medium with I Love Lucy, she moved on to The Lucy Show and then to Here’s Lucy, where she played Lucy Carter, a good-natured but scatterbrained widow working at a Los Angeles employment agency. At fifty-nine, Ball was not merely the star of the show. She was a hands-on producer and director who ran the production with an iron grip.

The idea of booking Richard Burton as a guest star was a major coup. The episode, titled Lucy Meets the Burtons, opened the third season of Here’s Lucy. In it, Burton plays himself, visiting Los Angeles with Taylor. He buys her a massive sixty-nine-carat diamond ring, and to escape the attention of fans, he disguises himself as a plumber.

Lucy Carter spots him, mistakes him for the real thing, and drags him to her office to fix a leaky sink. What follows is pure farce, with Burton forced to recite Shakespeare with a plumber’s wrench in hand, uttering lines like to be or not to be a plumber. Taylor appears later in the episode, and the plot spirals into a chase when the diamond ring becomes stuck on Lucy’s finger. Burton ends up soaked with water and wrestling with a pipe.

The audience ate it up. The episode aired on September 14, 1970, and drew a massive viewership. It became one of the most memorable installments in the series’ run. But the laughter on screen did not reflect the mood on set.

Burton’s own account of the production, written in his private diaries and published years after his death, paints a far darker picture. Those who had told us that Lucille Ball was very wearing were not exaggerating, he wrote. She is a monster of staggering charmlessness and a monumental lack of humor. The complaints were specific.

Ball kept interrupting rehearsals to give Burton notes on how to play scenes funnier. Her approach was rooted in broad physical comedy, exaggerated facial expressions, and precise timing built from years of vaudeville-style performance. Burton, trained in classical theater and accustomed to subtlety and understatement, found the direction grating. He believed her style was nothing more than over-the-top mugging, and he had no patience for being told how to deliver a line by someone he considered a comic technician rather than an artist.

The clash was more than a difference of taste. It was a collision of two working methods and two egos. Ball was a notorious perfectionist who controlled nearly every aspect of her productions. She had a reputation for firing writers mid-season and demanding endless retakes until a scene met her exact standards.

Burton, by contrast, approached acting as an intellectual discipline. He saw the sitcom as a frivolous format, well beneath his abilities, and he had accepted the role only as a favor to a friend. Almost immediately, he regretted it. His diary entries from the period complain about endless retakes and what he described as Ball’s hysterical demands.

Reports from the set suggest he chain-smoked his way through the production, making little effort to hide his disdain. For her part, Ball had her own grievances. She claimed to admire Burton’s talent but found him stuck-up, unwilling to adapt to the rhythms of television comedy. She was the boss on her own set, and she was not about to let a visiting movie star dictate the terms.

The result was a working relationship defined by friction, with each side convinced the other was wrong. The episode’s success did nothing to soften Burton’s opinion. On screen, the chemistry between the two stars read as playful and charming. Off screen, the animosity was total.

Even Elizabeth Taylor, whose small role in the episode added star power, reportedly rolled her eyes at the chaos unfolding around her. One detail from the production stands out as particularly revealing of the strange world the two stars inhabited. The diamond ring used as the plot device was not a prop. It was a real sixty-nine-carat stone that Burton had recently given to Taylor as a gift.

The episode turned their actual jewelry into television entertainment, a level of extravagance that seemed almost surreal against the gritty, petty arguments over comedic timing. Despite the personal animosity, the appearance was a practical success. It boosted Here’s Lucy’s ratings and gave Burton a rare credit in American television. The episode remains available on streaming services today, and viewers can still watch the two legends trade comic lines and chase each other through slapstick set pieces, unaware of the hostility simmering just out of frame.

What makes the story memorable is not simply that two difficult personalities clashed. It is that the clash was so complete despite the obvious professional results. Burton went to his grave viewing Ball as a charmless tyrant. Ball went to hers viewing Burton as an arrogant snob.

Neither seemed willing to grant the other any grace, and the episode that brought them together became a monument to their mutual contempt, hidden beneath the polished surface of the finished product. The lives of the three stars ended in ways that seemed to match the dramatic arcs of their public personas. Richard Burton died of a cerebral hemorrhage on August 5, 1984. He was fifty-eight years old.

Elizabeth Taylor died of congestive heart failure on March 23, 2011, at the age of seventy-nine. Lucille Ball died on April 26, 1989, from a ruptured abdominal aortic aneurysm. She was seventy-seven.

The television episode they made together survives as a curious artifact of a moment when two titans of entertainment were brought together by the machinery of show business, collided, and produced something far more complicated than either of them ever admitted.
