How Erich Bergen Landed Anthony Radziwill
Bergen initially declined an audition for the lead role of JFK Jr., believing he was wrong for the part. “It was kind of wild,” he explained to Town & Country. When the role of Anthony Radziwill became available, Bergen experienced an immediate shift. “I thought, well, this is the role that’s right for me,” he revealed, noting his personal survival of a similar cancer diagnosis made the character deeply resonant. The Madam Secretary star has made men’s health advocacy a cornerstone of his life, encouraging medical screenings and early detection with the same urgency he brings to Anthony’s story.
Bergen’s decision to accept the role stemmed from genuine alignment. He recognized Anthony’s journey mirrored struggles he’d personally endured. The actor’s willingness to transform vulnerability into performance creates an authentic emotional landscape throughout the series, particularly in scenes depicting Anthony’s declining health and unwavering bond with his cousin John.

Anthony Radziwill’s Real Story
Anthony Radziwill was born in 1958 as the son of Lee Radziwill, sister of Jackie Kennedy Onassis, making him a member of America’s most storied political dynasty. He served as a television executive at ABC News and earned a law degree from Boston College Law School. Beyond credentials, Anthony was known for his charisma, warmth, and unshakeable loyalty to those closest to him. His relationship with JFK Jr. transcended typical cousin bonds; they were brothers in spirit, confidants, and best friends who navigated privilege and expectation together in the glaring spotlight of public fascination.
In 1989, Anthony received a devastating diagnosis: testicular cancer. Though he underwent treatment and initially entered remission, the disease proved relentless. It metastasized throughout his body, spreading to his lungs and other organs, requiring years of experimental treatments and constant medical surveillance. Despite the physical toll, he married Carole Bessette (sister of Carolyn Bessette-Kennedy) in 1994, and they remained devoted until his death on August 10, 1999, at age 40. His passing devastated JFK Jr., who would lose his own life just two months later in a plane crash.
The Love Story Portrayal and Cancer’s Emotional Weight
In the series, Bergen portrays Anthony as the emotional anchor in JFK Jr.’s life, the one person who understood the peculiar burden of Kennedy legacy combined with modern fame. The show doesn’t shy from depicting his cancer progression; viewers witness firsthand the moment Anthony reveals to John that his illness has advanced to a critical stage. One pivotal scene shows Anthony informing John that cancer has spread to his lungs—a turning point that underscores the series’ unflinching approach to mortality and medical reality.

“This just felt right for so many reasons. He was diagnosed with testicular cancer, and it stayed with me. It saved my life. And I wanted to use this platform to encourage men to seek necessary medical care.”
— Erich Bergen, on his choice to play Anthony Radziwill
Why Bergen’s Cancer Survival Shaped His Performance
Erich Bergen first revealed his cancer battle publicly in 2017, detailing his Stage I testicular cancer diagnosis from 2013. He underwent aggressive treatment, including surgery to remove the affected testicle and chemotherapy courses that tested his physical and mental resilience. By 2018, Bergen declared himself cancer-free, but the experience fundamentally altered his worldview and artistic approach. He became a vocal advocate for male health screenings, understanding intimately how silence and shame can delay life-saving diagnoses.
When offered Anthony Radziwill’s role, Bergen recognized an extraordinary opportunity to honor both his own journey and the real-life struggle that claimed his character’s life. His empathy informs every scene, every silent moment of pain, every gesture of love exchanged between cousins facing mortality. The performance resonates with audiences because Bergen walks the walk—he knows the fear, the hope, and the fragile gratitude of survival.
What Makes Love Story’s Portrayal Stand Out Among Kennedy Dramas?
Ryan Murphy’s Love Story differs from previous Kennedy narratives by centering emotional truth over historical spectacle. Rather than treating Anthony’s illness as subplot, the series integrates it as a defining current threading through every episode. Paul Anthony Kelly’s portrayal of JFK Jr. gains depth precisely because of Bergen’s presence—their dynamic captures a real kinship tested by mortality. The show strips away mythology to reveal two young men grappling with fame, love, family obligation, and the painful knowledge that time is running out for one of them.
Viewers consistently note that the Anthony Radziwill character provides emotional grounding amid the glamour and media chaos surrounding John and Carolyn. Bergen’s nuanced performance prevents Anthony from becoming a tragic footnote; instead, he emerges as the moral center, the person who loves without conditions or agendas. As episodes unfold toward March 26’s finale, audiences confront one of history’s most poignant what-ifs: two beloved cousins taken from the world within weeks of each other, their stories forever intertwined in American memory.
