Julian Fellowes had one person to thank at The Gilded Age Season 4 premiere — and he did not hold back. At the Plaza Hotel in New York City, the series creator called HBO chief Casey Bloys the show’s protector from its earliest days, just days before the new season arrives.

“I have a special place in my heart for Casey Bloys, our protector, our gladiator, our defender from very, very early days,” Fellowes said before the screening. “Anyone who enjoys the show owes him a great deal. I certainly do, and I say that with both pride and happiness.”

The tribute set the tone for a premiere steeped in the show’s own world — old money, new money, and the people who defend their place in it. Fellowes, who co-showruns the period drama with Sonja Warfield, has steered the series since its debut, and Bloys’ early backing has been central to its survival and growth.
The red carpet drew the show’s leading players, including Carrie Coon, Morgan Spector, Denée Benton and Cynthia Nixon, ahead of a season that promises the series’ biggest power struggles yet.
When does Gilded Age Season 4 premiere?
The eight-episode fourth season premieres Sunday, November 1, 2026, at 9 p.m. on HBO and HBO Max, with new episodes arriving weekly through December 20. Most of the main cast returns: Louisa Jacobson as Marian Brooke, Christine Baranski and Cynthia Nixon as Agnes van Rhijn and Ada Brooke, now Ada Forte, and Coon and Spector as Bertha and George Russell.
New faces join the fray too, including Jim Gaffigan as President Grover Cleveland, Dallas Roberts as Treasury Secretary Daniel Manning, and Elizabeth Marvel as Nurse Virginia Saville. According to HBO’s synopsis, Bertha Russell changed society at a cost, and now her family must reckon with the consequences as Agnes seizes an opportunity to regain her position, while Marian forges a new path and Peggy works to be accepted by her future in-laws.
Whether Season 4 proves to be a finale or a bridge to more, Fellowes made one thing clear at the Plaza: the show exists because someone believed in it early — and he wanted the room to know it.
