Cast of The Gilded Age: Full List, Replacements & Season 4

There’s something irresistible about a period drama that lets you peek into the drawing rooms of New York’s 19th-century elite. The Gilded Age has been doing just that since its premiere in January 2022, and viewers keep coming back for the cast of characters—both fictional and inspired by real dynasties. This guide traces the full cast from season 1 through the confirmed season 4 returns, with the facts about replacements and the real-life inspirations behind the characters.

Who is in the cast of The Gilded Age?

Main cast from season 1

• Carrie Coon as Bertha Russell (Rotten Tomatoes)
• Morgan Spector as George Russell (Rotten Tomatoes)
• Louisa Jacobson as Marian Brook (Rotten Tomatoes)
• Denée Benton as Peggy Scott (Rotten Tomatoes)

• Season 3 introduced Felicia Rashad as Elizabeth Kirkland and Brian Stokes Mitchell as Frederick Kirkland (YouTube news report)
• Ensemble additions include Donna Murphy, Debra Monk, Nathan Lane, Andrea Martin, Ben Lamb, Kelli O’Hara, Patrick Page (TV Guide cast list)

Confirmed returns for season 4

According to reports, returning cast likely includes Carrie Coon, Christine Baranski, Cynthia Nixon, Morgan Spector, and Denée Benton (YouTube news report). The full cast list has not been officially released as of early 2025.

What this means: The core ensemble is built around a mix of Broadway royalty and rising stars, giving the show a theatrical depth that matches its lavish production design.

Who did Carrie Coon replace in The Gilded Age?

Original casting of Bertha Russell

Carrie Coon replaced Amanda Peet as Bertha Russell before production began (Rotten Tomatoes). This casting change occurred prior to the series premiere and is confirmed by the final credits.

The trade-off: Amanda Peet’s departure meant losing a name from a different dramatic range, but Coon’s portrayal of Bertha Russell became one of the most acclaimed performances of the series.

Is The Gilded Age based on real people?

Vanderbilt family inspiration

The series is loosely inspired by the Vanderbilt family and other Gilded Age dynasties (Rotten Tomatoes). The Russells are a fictionalized version of the Vanderbilts, with George Russell echoing Cornelius Vanderbilt.

Gladys Russell real-life counterpart

The character Gladys Russell is partly based on real heiress Gladys Vanderbilt. Hetty Green, portrayed in the series, was the richest woman in the United States during the Gilded Age.

Why this matters: The historical grounding gives the series an educational appeal, but viewers should treat it as fiction inspired by fact, not a documentary.

Has The Gilded Age been canceled?

Season 4 renewal confirmation

No, the series has not been canceled. HBO confirmed a fourth season in July 2025, according to a report (YouTube news report). The show is listed by TV Guide as running from 2022 to 2025.

Returning cast members for season 4 are expected to include the main ensemble, though the full list remains unofficial (YouTube news report).

The pattern: HBO treats The Gilded Age as a prestige drama comparable to The Crown – steady renewals with a multi-year arc.

What is the connection between Downton Abbey and The Gilded Age?

Julian Fellowes as shared creator

Both series were created by Julian Fellowes (Rotten Tomatoes). The shows share a similar tone of upstairs-downstairs social drama, but are set in different countries and eras.

Universe crossover

Julian Fellowes has stated that the two series exist in the same universe. A character from Downton Abbey – the Dowager Countess’s relative – appears in The Gilded Age, confirming the connection.

“They are two entirely different worlds, but they exist in the same universe.”

– Julian Fellowes, creator, as reported by interview coverage

The implication: If you love the sprawling family drama of Downton Abbey, The Gilded Age offers a fresh setting with the same creator’s touch. For another HBO prestige drama with a sprawling cast, see our guide to House of the Dragon Season 3.

Clarity: What’s confirmed and what’s unclear

Confirmed facts

• Carrie Coon replaced Amanda Peet as Bertha Russell (Rotten Tomatoes)

For anyone who loves immersive period drama with a sharp social lens, The Gilded Age is worth your time – and the upcoming season promises more of the same rich storytelling. If you’ve been on the fence about starting, now is the perfect moment to catch up before the cast returns with new storylines led by Carrie Coon, Morgan Spector, and the rest of the ensemble.
