Ryan Murphy's newest anthology series, Love Story: John F. Kennedy Jr. & Carolyn Bessette, is now captivating audiences on FX and Hulu. The nine-episode limited series, which premiered on February 12, 2026, explores the whirlwind courtship, high-profile marriage, and tragic end of one of the 20th century's most iconic couples .
Inspired by Elizabeth Beller's book Once Upon a Time: The Captivating Life of Carolyn Bessette-Kennedy, the series charts "the complex and heartbreaking journey of a couple whose private love became a national obsession" . With new episodes airing weekly through the finale on March 26, here's a complete guide to the cast bringing these legendary figures to the screen .

The Lead Couple
Paul Anthony Kelly as John F. Kennedy Jr.
Taking on the role of America's "most eligible bachelor" is Paul Anthony Kelly, a relative newcomer and former Brooks Brothers model . To prepare for the part, Kelly immersed himself in research, including listening to an audiobook of John Jr. narrating his father's book Profiles in Courage "on Spotify all day long, just restarting it over and over again" . The series depicts Kennedy as "a handsome and charming idealist determined to make his mark on the world, a fixture of American public life in both politics and pop culture" .

Sarah Pidgeon as Carolyn Bessette
Tony Award-nominated performer Sarah Pidgeon (Stereophonic) portrays Carolyn Bessette, the fiercely independent Calvin Klein executive whose "cosmopolitan yet understated all-American style" made her a fashion icon . The series emphasizes that Bessette was "a star in her own right" who "rose from being a sales assistant to an executive at Calvin Klein and became a trusted confidante of its eponymous founder" . Pidgeon noted at the premiere that "their story is unfinished, and I think that's a big reason why people continue to be so invested in and protective of them and still hold them dear" .

The Kennedy Family
Naomi Watts as Jackie Kennedy Onassis
Two-time Oscar nominee Naomi Watts steps into the role of the iconic Jackie Kennedy Onassis. At the series premiere, Watts reflected on portraying the former first lady during a challenging period of her life: "She wanted to impart her wisdom to him. She had experienced extreme tragedy in many ways, she was a hurt person and had been broken down by that point. But she was trying to say to him, 'You've got this.' She was trying to pass on her strength and wisdom, and her hope he could uphold the legacy" .

Grace Gummer as Caroline Kennedy
Grace Gummer, daughter of Meryl Streep, portrays Caroline Kennedy, John Jr.'s sister. The series depicts their bond as one "founded on loyalty and mutual respect" . Gummer's Caroline serves as a grounding presence amid the family's complex dynamics.

Sydney Lemmon as Lauren Bessette
Sydney Lemmon plays Carolyn's sister Lauren, who tragically died alongside the couple in the 1999 plane crash. The series opens with the three boarding the ill-fated Piper Saratoga at a small airport—"a lingering shot of the aircraft flying away is potent for those who know that Kennedy's Piper Saratoga crashed off the coast of Martha's Vineyard" .

The Fashion World
Alessandro Nivola as Calvin Klein
Alessandro Nivola portrays the legendary fashion designer Calvin Klein, playing a pivotal role in the series as the man who recognized Carolyn's talent and became her mentor.

In a "CBS Sunday Morning" interview, Schlossberg called the series a "grotesque display of someone else's life" and urged viewers to watch it "with one letter in mind, and that's a capital 'F' for fiction" .

Schlossberg previously commented on first-look photos in 2025, writing, "HEY RYAN — admiration for John is great but maybe consider DONATING PROFITS TO THE KENNEDY LIBRARY, thanks." Murphy responded at the time, "I absolutely will" .

A Story That Endures
As one premiere guest observed, "The dream is to die young but live forever, right? So there's something dangling and tempting about their story, because we know they're preserved that way" . Whether critics find the series illuminating or superficial, the fascination with John and Carolyn shows no signs of fading.
