HBO’s period drama isn’t just about the hats. Honestly, if you look at The Gilded Age cast, you’ll realize it’s actually a stealthy takeover of the New York theater scene. Julian Fellowes didn't just go for big-name movie stars to fill the shoes of the Astors and the Russells. He went for the people who spend eight shows a week singing and crying on 42nd Street.
It’s a specific vibe.
When you watch Christine Baranski and Cynthia Nixon trade barbs over tea, you aren’t just watching two actresses. You are watching decades of stage training collide with high-budget production. That’s the secret sauce. Most period dramas feel a little like dress-up, but this cast makes the 1880s feel lived-in because they understand the posture, the diction, and the sheer weight of a corset.
The Broadway DNA of the Russell and Van Rhijn Households
Most people watching at home might recognize Carrie Coon from The Leftovers, but the Broadway nerds know her from Who's Afraid of Virginia Woolf?. That’s the thing about this show. It’s a theater kid’s fever dream. Take Morgan Spector. He plays George Russell with this simmering, "I will ruin your life and then take you to dinner" energy. He’s a stage veteran too.
The casting directors, Bernard Telsey and Adam Caldwell, basically raided the Tony Awards archives. They needed people who could handle the heightened language without sounding like they were reading a history textbook.
Look at the numbers. At one point during season two, the cast combined for something like 40 Tony nominations. Audra McDonald, who plays Dorothy Scott, has six Tony wins. Six! That is a record. When she stands in a room with Denée Benton (Peggy Scott), who herself was a breakout in Natasha, Pierre & The Great Comet of 1812, the power dynamic is palpable. You don't get that kind of gravity from just anyone.
The "Old Money" side is anchored by Christine Baranski as Agnes van Rhijn. Baranski is the queen of the dry delivery. She’s been doing this since the early 80s on stage. Her chemistry with Cynthia Nixon, who plays the more empathetic Ada Brook, works because they’ve both spent their lives in the New York acting ecosystem. Nixon isn't just Miranda from Sex and the City here; she's a classically trained powerhouse who knows exactly how to play the "meek sister" without becoming a caricature.
Why The Gilded Age Cast Doesn't Feel Like Downton Abbey
There is a huge misconception that this is just Downton Abbey: New York Edition. It isn't. The British version of Fellowes' world relied on a very specific type of UK class rigidity. The American version is about New Money—the "vulgarians" as Agnes calls them—smashing their way into society.

To pull that off, you need a different kind of actor.
The Russells are played by Carrie Coon and Morgan Spector. They are the engine of the show. Coon brings a sharp, modern edge to Bertha Russell. Bertha isn't a victim of society; she’s a predator. If you’ve seen Coon on stage, you know she has this way of holding her body that says she’s the smartest person in the room. It’s why the The Gilded Age cast feels so much more aggressive than the Crawley family.
Then you have the downstairs staff. In many shows, these roles are afterthoughts. Here? You’ve got Michael Cerveris playing a valet. Cerveris is a legend. He’s played Sweeney Todd and Bruce Bechdel. Seeing him play a quiet, observant servant is like seeing a Ferrari parked in a 20 mph zone. It adds a layer of "if you know, you know" for the audience.
The Surprising Newcomers and the "Nepo Baby" Conversation
We have to talk about Louisa Jacobson. She plays Marian Brook. For those who didn't catch the trivia early on, she’s Meryl Streep’s youngest daughter.
People love to jump on the "nepo baby" bandwagon, but Jacobson actually fits the role of the naive outsider quite well. Marian is supposed to be the audience surrogate—the person who doesn't understand why you can't talk to the help or why you must leave a calling card. Her performance is intentionally more restrained than Baranski’s. It creates a foil. If everyone were chewing the scenery, the show would be exhausting.
But then you have the breakouts like Harry Richardson (Larry Russell) and Blake Ritson (Oscar van Rhijn). Ritson, in particular, plays Oscar with this wonderful, oily desperation. He’s trying to marry for money while hiding his true self, and he does it with a smirk that makes you both hate him and root for him.
The Cultural Significance of the Scott Family
One of the most important parts of the The Gilded Age cast is the inclusion of the Black elite in 19th-century Brooklyn. This isn't a story we usually see. Peggy Scott, played by Denée Benton, provides a lens into a world of Black professionals, journalists, and landowners that history books often skip over.

Benton’s performance is crucial. She has to navigate two worlds: the white-dominated Van Rhijn house and her father’s prosperous but restrictive home in Brooklyn. Her father, played by John Douglas Thompson, is often cited as one of the greatest Shakespearean actors of our time. When he and Benton have a confrontation, it’s not just a TV scene. It’s a masterclass in dramatic tension.
The show doesn't treat their storyline as a "side plot." It’s woven into the fabric of how New York was actually built. This isn't just diversity for the sake of a checklist; it’s an accurate, though often ignored, part of American history. The actors bring a weight to these roles that prevents the show from feeling like a soap opera.
The Guest Stars You Definitely Recognized
Part of the fun of watching this show is the "Hey, it’s that guy!" factor. Because it films in and around New York, the guest list is insane.
- Nathan Lane: He plays Ward McAllister with a Southern accent that is... a choice. But it’s Nathan Lane. He’s a peacock in human form.
- Laura Benanti: She showed up as a glamorous widow, adding even more Tony-winning sparkle to the screen.
- Robert Sean Leonard: Yes, Dr. Wilson from House. He pops up as a rector.
- Donna Murphy: She plays Caroline Astor, the final boss of New York society. Murphy is a Broadway icon, and her presence is exactly what you need for the woman who literally decided who was "in" and who was "out."
Behind the Scenes: The Training
The actors didn't just show up and put on hats. They had to work with historians and movement coaches. You can see it in how Carrie Coon sits. She never touches the back of her chair. That’s intentional. The corsets of the 1880s were designed to push the torso forward.
There’s a specific "Gilded Age walk." Women had to glide because their dresses were so heavy. If you watch Denée Benton or Louisa Jacobson, they aren't striding like they’re in jeans. They are managing layers of petticoats and bustles.
The men have it hard too. The high collars of the era were stiffened with starch to the point of being sharp. It forces a certain chin-up attitude. Morgan Spector has mentioned in interviews that the clothes do 50% of the acting for you. You can't slouch in a frock coat.
What People Get Wrong About the Acting Style
Some critics complained early on that the acting felt "stiff."

That’s actually the point.
The Gilded Age was a period of extreme social performance. Everyone was playing a character. Agnes van Rhijn is playing the "Guardian of the Old Ways." Bertha Russell is playing the "Next Big Thing." The cast isn't being wooden; they are portraying people who were terrified of making a social faux pas. The cracks in the armor—like when Bertha loses her temper or Ada shows a bit of steel—only work because the rest of the time they are so disciplined.
Practical Takeaways for Fans of the Show
If you’re obsessed with the cast and want to see more of them, you’re in luck because most of them are consistently working in New York.
1. Check the Playbill. Before you visit NYC, check who from the cast is currently on Broadway. It is almost a guarantee that at least two or three regulars are in a limited-run play or musical.
2. Follow the "Theater to TV" Pipeline. If you like the acting style in The Gilded Age, look into other shows cast by Telsey + Company. They have a specific knack for finding stage actors who can translate to the screen without losing their presence.
3. Visit the Real Locations. A lot of the cast filmed on location in Newport, Rhode Island, and Troy, New York. You can actually tour the "summer cottages" (mansions) where characters like the Russells and the Astors would have spent their July and August. Seeing the scale of these rooms in person makes you appreciate the actors' ability to fill that space even more.
The brilliance of the The Gilded Age cast lies in their collective background. By prioritizing the stage-trained elite of New York over Hollywood A-listers, the show achieved an authenticity that high-definition cameras usually strip away. It’s a love letter to the theater, wrapped in silk and tied with a very expensive ribbon.
To truly appreciate the performances, watch the scenes where no one is talking. Watch the way Donna Murphy’s Mrs. Astor looks at a room, or how Michael Cerveris watches a door. That’s where the real acting happens. It’s in the silence, the posture, and the subtle shift of a bustle.
For your next watch, pay attention to the background players during the ballroom scenes. Many are local dancers and theater students who have to maintain that same rigid 1880s discipline for twelve-hour shoot days. It’s an ensemble effort that extends far beyond the top billing, making the show a definitive document of New York’s acting pool in the mid-2020s.
