“Feud” Season 2 at FX has added Tom Hollander, Diane Lane, and Calista Flockhart to its cast, Variety has learned exclusively from sources.

The trio join previously announced series stars Naomi Watts and Chloë Sevigny. The second season of the Ryan Murphy anthology series will tell the true story of how Truman Capote was friends with numerous members of New York high society until he published excerpts of his unfinished novel “Answered Prayers,” with the excerpts serving as a tell-all about the city’s elite.

It was previously announced that Watts will play famed socialite Barbara “Babe” Paley, while Sevigny will play C.Z. Guest. Hollander will star as Capote, with Lane playing Nancy “Slim” Keith and Flockhart playing Lee Radziwill.

Reps for the actors, FX, and 20th Television declined to comment.

Hollander is known for his roles in films such as the 2005 adaptation of “Pride & Prejudice” as well as “Gosford Park” and the “Pirates of the Caribbean” franchise. He has also starred in TV shows such as “The Night Manager,” “Taboo,” and “Rev.,” the last of which he also co-created. He received three consecutive BAFTA nominations for “Rev.” and won the BAFTA for best supporting actor for “The Night Manager.” He will next be seen in the second season of “The White Lotus” at HBO.

Hollander is repped by United Agents, Anonymous Content, and Bloom Hergott.

Lane recently signed on to star opposite Jeff Daniels in the Netflix limited series “A Man in Full.” She also recently starred in the FX adaptation of the graphic novel series “Y: The Last Man.” She is primarily known for her roles in films like “Under the Tuscan Sun,” “Unfaithful,” and “Hollywoodland.” Her work in “Unfaithful” earned her both an Academy Award and Golden Globe nominations, while she was also nominated for Golden Globes for “Under the Tuscan Sun” and the TV movie “Cinema Verite.”
