Ahead of the premiere of "Feud: Capote vs. the Swans," the cast and executive producer Ryan Murphy met for a screening at New York's Museum of Modern Art. There were also three other honored guests: Treat Williams' wife, Pam, and their adult son and daughter, Gill and Ellie. Murphy led a round of applause in Williams' memory, and shared a poignant memory. Months earlier, at the series' wrap party, Williams told the producer (via People), "I loved every minute."

Pam Williams backs this up. In a separate interview with People, she said, "He was truly in his element working with the best of the best in every department on this project and couldn't have been happier." Pam also recalled how the "Feud" crew offered their support after her husband's tragic death. It's a loss still fresh in the family's hearts: "I think because of the suddenness of it, there was absolutely no preparation, so I'm still grappling with the fact that it happened and that he's really gone," Pam Williams told the outlet. "It just feels like such a hole in our family and the fabric of the world. The whole atmosphere feels different."

Gill added that it helps to be able to watch his father's performances: "That's something you're very lucky to have if your parent is an artist, especially when they're as prolific as him, because you get to, in many ways, still be with them through that."
