Bold take: The Gilded Age is expanding its cast and reshuffling loyalties, signaling bigger game-play in Season 4. But here’s where it gets controversial: will these new power moves help or complicate the delicate balance between old money and new money in New York society?
HBO’s The Gilded Age has promoted Jordan Donica and Ashlie Atkinson to series regulars for its upcoming fourth season. In addition, six actors will join the recurring cast: Taylor Trensch, James Scully, Dennis Haysbert, Maggie Kuntz, Neal Huff, and Tony Award-winner Bonnie Milligan.
What’s changing in Season 4 is already shaping the drama. Bertha Russell (Carrie Coon) has reshaped society at a personal cost, and Agnes van Rhijn (Christine Baranski) is seizing a chance to reclaim influence. Marian (Louisa Jacobson) is pursuing a new path, while Peggy (Denée Benton) works to win acceptance from her in-laws. The era’s risks—ambition, status, and marriage—remain front and center: in this world, wishing for power often invites unintended consequences.
Season 3 concluded with a pivotal moment at a Newport gala: Peggy shared a magical, surprising moment with Dr. William Kirkland (Donica). He proposed on one knee, unafraid of his parents’ possible disapproval, signaling a bold, defiant commitment. In Season 4, Peggy may try to bridge gaps with William’s parents if a wedding progresses, though Peggy can rely on Kirkland’s steadfast support.
Agnes appears to have rekindled her own spark after last season’s struggle for rank within the family, especially with Ada Forte (Cynthia Nixon) now holding higher status. The Season 4 logline hints at a renewed focus on the clash between old money and new money, with Agnes positioned as a formidable challenger.
Meanwhile, Bertha’s end-of-season hint at possible divorce from George Russell (Morgan Spector) raises questions about whether the family’s financial concerns will recede or whether Bertha’s social ambitions will overshadow her roles as wife and mother. The show previously set a controversial note by edging toward divorced respectability in this era; how that thread will unfold remains to be seen. And yes, their Season 1 romance still lingers in memory.
George’s near-fatal health scare at the end of Season 3, narrowly averted by Peggy’s partner Dr. Kirkland, will likely leave lasting effects for those characters. That kind of life-changing event tends to reshuffle loyalties and priorities in this high-stakes world.
Returning cast members confirmed for Season 4 are Carrie Coon, Christine Baranski, Louisa Jacobson, Denée Benton, Jordan Donica, and Ashlie Atkinson (reprising Mamie Fish). The new recurring players are:
- Taylor Trensch as Oliver, a fresh addition to the van Rhijn household
- James Scully as Lee Klein, an artist whose first painting debuts at a landmark Society event and an apprentice to William Merritt Chase
- Dennis Haysbert as Dr. Reginald Harris, Kirkland’s mentor who travels to New York to fundraise for Freedman’s Hospital and forms a surprising connection
- Maggie Kuntz as Fiona Summers, a free-spirited cousin of the Astors who pushes the boundaries of convention
- Neal Huff as John D. Rockefeller, a self-made magnate with a devout Baptist faith and a philanthropic streak who doesn’t always see eye to eye with other robber barons
- Bonnie Milligan as Mrs. Knapp Curtis, editor of The Ladies’ Home Journal and a trailblazer in women’s publishing
The show remains a collaborative effort created, written, and executive produced by Julian Fellowes, with Sonja Warfield as writer and executive producer. Additional executive producers include Gareth Neame, David Crockett, Salli Richardson-Whitfield, Kate Churchill, Bob Greenblatt, and Elaine Aronson. Historical insights are provided by Erica Dunbar (co-executive producer), with Davita Scarlett and Holly Rymon as co-executive producers.
