Selome Hailu Molly Ringwald has joined the cast of “Feud” Season 2, Variety has learned. According to sources, she will play Joanne Carson, the second wife of Johnny Carson. Reps for FX and 20th Television declined to comment. Season 2 of Ryan Murphy’s anthology series on FX follows the true story of how Truman Capote (Tom Hollander) 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. Carson, however, remained close with Capote until his death in 1984.
