The Gilded Age Season 3 is officially in production — and celebrating its Emmy nominations!

The cast and crew returned to the set in early July, and by the looks of the cast’s social media posts from set, everyone’s thrilled to be back. The excitement only grew when the series received six Emmy nominations on July 17, including Outstanding Drama Series and acting nominations for Carrie Coon and Christine Baranski. The production celebrated with a lunch party on set during Season 3 filming.

HBO revealed the Season 3 logline when announcing four new cast membersPhylicia RashadBrian Stokes MitchellVictoria Clark, and Jordan Donica — on June 17. The logline teases that the great houses of New York City must get their homes “in order” as everyone’s lives are turned “upside down” by the new-money takeover of the social elite.

“The American Gilded Age was a period of immense economic and social change, when huge fortunes were made and lost overnight,” it says. “With the old guard officially deposed, New York society finds itself turned upside down, and all must get their house in order. But even those at the helm of this new era may find that change comes at a cost.”

Leading the new guard is Mrs. Bertha Russell (Coon), who won the Season 2 opera war against Mrs. Astor (Donna Murphy) when upstaging the Academy of Music’s opening night at the new Metropolitan Opera. Coon and Murphy will be back for more in Season 3, as will Morgan Spector (George Russell), Louisa Jacobson (Marian), Denée Benton (Peggy), Harry Richardson (Larry), Taissa Farmiga (Gladys), and more. One of the biggest points of intrigue of Season 3 will be how the Van Rhijn household shifts now that Ada (Cynthia Nixon) is the woman in charge. Agnes (Baranski) won’t love this loss of control!

Page remarked on 1800s men’s fashion on Instagram in July.

“Resting between takes on ‘The Gilded Age’ set yesterday. How did those 19th century guys do it? The wool pants, the high starched collars! Yesterday wasn’t even that hot, but it felt suffocating outside. Not complaining!” he wrote. “I’m so grateful to be able to play in this arena! Just noting that values have changed—and making a good appearance used to be much higher on the list. Can’t wait to share season three with you!”
