The glittering world of New York’s elite is getting ready for more drama. HBO has officially revealed the plot for The Gilded Age Season 4, and it looks like the Russell family is in for a rough ride. Along with the story details, the network confirmed a big promotion for one cast member and several new actors joining the period drama, including a comedian playing a US President.
The official logline for the upcoming season tells us that getting everything you want might come with a heavy price. Bertha Russell finally changed society, but the cost to her family is just starting to show. Across the street, Agnes van Rhijn sees a chance to get her old power back. At the same time, the younger generation—Marian Brook and Peggy Scott—are trying to build their own futures, with Peggy facing new challenges from her future family .
Kelley Curran Gets Promoted to Series Regular for Season 4
One of the biggest pieces of news for the upcoming season is the promotion of Kelley Curran. She has played the role of Enid “Turner” Winterton since the very first season. Turner started as a maid in the Russell household but made a daring move by marrying a wealthy man to climb the social ladder .
For the fourth season, Curran will now be a series regular. This means her character will have a much bigger role in the story going forward. This makes a lot of sense when you think about how Season 3 ended. Oscar van Rhijn was starting to show interest in Turner, thinking about a marriage of convenience. With both Oscar and Turner wanting to secure their places in society, this storyline is likely to become very important in the new episodes .
Jim Gaffigan and More Join The Gilded Age Season 4 Cast
The fourth season is also adding some fresh faces. Four new actors are joining the show as guest stars, and they will play some famous historical figures .
Comedian and actor Jim Gaffigan will step into the shoes of Grover Cleveland, the 22nd President of the United States. His character comes to New York to build relationships with the wealthy and powerful elite .
Alongside him, Dallas Roberts will play Daniel Manning, who was the Secretary of the Treasury under President Cleveland. He is described as a seasoned politician .
Elizabeth Marvel is joining the cast as Nurse Virginia Saville. She works at a place called the Neighborhood Settlement House on the Lower East Side, which helps the less fortunate. This role could bring a new perspective on the huge gap between the rich and poor during that era .
Finally, Tony Award winner Andrew Burnap will play Porter, a young man from a good family. He has an Ivy League education and money he wants to invest in new and exciting businesses .
Returning Cast Members Confirmed for The Gilded Age Season 4
Fans will be happy to know that almost all of their favorite characters are coming back. The main cast members are all set to return. This includes Carrie Coon as Bertha Russell and Morgan Spector as George Russell. We will also see Christine Baranski (Agnes van Rhijn), Cynthia Nixon (Ada Brook), and Louisa Jacobson (Marian Brook). Denée Benton is back as Peggy Scott, along with Harry Richardson as Larry Russell and Blake Ritson as Oscar van Rhijn. Taissa Farmiga will also return as Gladys Russell, and the legendary Audra McDonald is back as Dorothy Scott .
This follows earlier news that Jordan Donica, who plays Dr. William Kirkland, and Ashlie Atkinson, who plays Mamie Fish, have also been promoted to series regulars for the fourth season. This confirms that Peggy’s relationship with William and her struggle to win over his family will be a central part of the story .
What Will Happen in The Gilded Age Season 4? A Look at the Plot
The official plot details give us a clear picture of where everyone will be when the new season starts.
For Bertha Russell, the victory she worked so hard for has turned sour. She finally got what she wanted and changed New York society to put herself at the top. But as the logline says, it came at a cost . The end of Season 3 showed her marriage to George falling apart. After George was shot and recovered, he told Bertha he wasn’t sure if he loved or trusted her anymore. He left for New York without her, leaving their future very uncertain. Now that their daughter Gladys is pregnant, Bertha has the family name she wanted, but her own family is breaking apart .
Across 61st Street, Agnes van Rhijn is not going to sit quietly. The logline says she will “seizes an opportunity to regain her position” . With Bertha’s personal life in chaos, Agnes might find a way to win back some of the social power she lost.
For the younger women, life is also changing. Marian Brook is ready to “forge a new path” for herself . This likely means her relationship with Larry Russell will move forward. After all the secrets came out, the two seem to be on track for a future together.
Peggy Scott has a new challenge. She is engaged to the wonderful Dr. William Kirkland, but the logline says she must “work to be accepted by her future in-laws” . This will not be easy, as William’s mother has already shown she does not approve of Peggy’s career as a working woman. Peggy will have to fight for her place in this new family while also dealing with her own ambitions.
