Truman Capote’s legend endures — for his writings (especially the true-crime novel “In Cold Blood”), his relationship with Harper Lee (immortalized in “To Kill a Mockingbird”), his childhood in Alabama (lovingly depicted in “A Christmas Memory”), his flamboyant love of the national spotlight, his self-destructive descent into booze and drugs, and more.

But there’s a chapter of Capote’s life that’s not quite as well known, and it’ll be highlighted this week on TV.

“Feud: Capote vs. the Swans” an eight-episode series with an all-star cast, makes its debut on Wednesday at 9 p.m. CT on FX. Tom Hollander of “The White Lotus” stars as Capote in the prestige project, teaming with actresses such as Naomi Watts, Diane Lane, Demi Moore, Molly Ringwald, Chloe Sevigny and Calista Flockhart.

“Capote vs. the Swans” is the second installment in Ryan Murphy’s “Feud” anthology for FX, and it tells a story of friendship and betrayal, society and scandal, power and punishment, set in New York City during the 1960s and ‘70s. Like the first season of “Feud,” which focused on the rift between Hollywood legends Bette Davis and Joan Crawford as they were filming “Whatever Happened to Baby Jane?,” the new season has divas aplenty.

The egotistical and ambitious Capote might be the biggest diva of all, interacting with a cluster of New York socialites he calls “the swans,” and eventually writing about them in a way that causes outrage among the women and results in his social demise.

Here’s how FX describes “Capote vs. the Swans” in a press release:

“Acclaimed writer Truman Capote (Tom Hollander) surrounded himself with a coterie of society’s most elite women — rich, glamorous socialites who defined a bygone era of high society New York — whom he nicknamed ‘the swans.’ Beautiful and distinguished, the group included grande dame Barbara ‘Babe’ Paley (Naomi Watts), Slim Keith (Diane Lane), C.Z. Guest (Chloë Sevigny) and Lee Radziwill (Calista Flockhart). Enchanted and captivated by these doyennes, Capote ingratiated himself into their lives, befriending them and becoming their confidante, only to ultimately betray them by writing a thinly veiled fictionalization of their lives, exposing their most intimate secrets.

“When an excerpt from the book, ‘Answered Prayers,’ Capote’s planned magnum opus, was published in Esquire, it effectively destroyed his relationship with his swans, banished him from the high society he so loved and sent him into a spiral of self-destruction from which he would ultimately never recover.”

The series is based on a 2021 book by Laurence Leamer, “Capote’s Women: A True Story of Love, Betrayal and a Swan Song for an Era.” Murphy — the creator and producer of “American Horror Story,” “Glee,” “American Crime Story,” “Monster: The Jeffrey Dahmer Story” and more — told The New York Times he’d long been fascinated by Capote, and reading Leamer’s book inspired him to choose the topic for a new season of “Feud.”

“It’s very easy to do a show where people are just nasty to each other,” Murphy said. “But feuds are never about hate. They’re about love.” This period of Capote’s life also illustrates “the very fragile, wonderful relationships that exist many times between gay men and straight women,” Murphy told The New York Times.

Capote evidently valued his friendships with the high-profile and influential women, but placed more importance on his career as a writer and provocateur. Capote also assumed his “swans” wouldn’t recognize themselves in the magazine excerpt of “Answered Prayers,” reportedly telling biographer Gerald Clarke they were “too dumb.”

Capote’s downward spiral after being shunned by his society pals was documented by Clarke, who credits extensive interviews with the author and “several hundred others” in the source notes for his 1988 biography. However, the FX series promises to bring the entire tale to vivid life for TV viewers, and give them extra insight into the colorful and eccentric Capote, who died in 1984 at age 59.

If you watch: “Feud: Capote vs. the Swans” premieres with two episodes on Jan. 31 at 9 p.m. CT on FX and FXX. The eight-episode series continues on Wednesdays at 9 p.m. CT. Episodes also air the following day on Hulu.
