HBO has handed a Season 4 renewal to Julian Fellowes’ period drama The Gilded Age. The pickup comes ahead of the Season 3 finale on August 10, which will wrap some storylines while setting up more drama and intrigue.

The Gilded Age, which leans into the New York theater community for its strong — and expansive — ensemble cast, has been a true word-of-mouth phenomenon. Launching on HBO’s lower-profile Monday night, it defied the odds and drew a solid viewership to earn a Season 2 renewal. Moving to HBO’s marquee Sunday night, The Gilded Age has been on an upswing since, finding a new gear with its current third season.

Premiere-night viewing has grown for five consecutive weeks, with Episode 5 drawing a new series high of 4 million U.S. cross-platform viewers within its first three days of availability. It was accompanied by a new weekly viewership high on HBO Max. Season-to-season, The Gilded Age is running up by 20%.

“We couldn’t be prouder of the undeniable viewership heights The Gilded Age has achieved this season,” said Francesca Orsi, EVP, HBO Programming, Head of HBO Drama Series and Films. “Transporting us to 1880s New York City, Julian Fellowes and the enormously talented cast and crew have created a “cant-miss it” entertainment experience from week to week, and we’re delighted to continue exploring these characters’ grand ambitions for what we promise will be a thrilling fourth season.”

The Gilded Age, a co-production between HBO and Universal Television, a division of Universal Studio Group, has earned seven Emmy nominations to date, including for Outstanding Drama Series, and one SAG Award nomination for Outstanding Performance by an Ensemble in a Drama Series.

“Thanks to Julian and the phenomenally talented cast and crew, each season of The Gilded Age delivers stories rich in drama and history, stellar performances and stunning production value,” said Erin Underhill, President, Universal Television. “Every moment spent in this world and with these characters only deepens our love for the show, and we’re so happy that our partners at HBO and audiences around the world are clamoring for more.”

In Season 3, following the Opera War, the old guard is weakened and the Russells stand poised to take their place at the head of society. Bertha sets her sights on a prize that would elevate the family to unimaginable heights while George risks everything on a gambit that could revolutionize the railroad industry — if it doesn’t ruin him first. Across the street, the Brook household is thrown into chaos as Agnes refuses to accept Ada’s new position as lady of the house. Peggy meets a handsome doctor from Newport whose family is less than enthusiastic about her career. As all of New York hastens toward the future, their ambition may come at the cost of what they truly hold dear.

The Season 3 cast includes Carrie Coon, Christine Baranski, Cynthia Nixon, Morgan Spector, Louisa Jacobson, Denée Benton, Taissa Farmiga, Harry Richardson, Blake Ritson, Ben Ahlers, Ashlie Atkinson, Dylan Baker, Kate Baldwin, Victoria Clark, John Ellison Conlee, Michael Cumpsty, Kelley Curran, Jordan Donica, Jessica Frances Dukes, Claybourne Elder, Amy Forsyth, Jack Gilpin, LisaGay Hamilton, Ward Horton, Simon Jones, Sullivan Jones, Celia Keenan-Bolger, Ben Lamb, Nathan Lane, Andrea Martin, Audra McDonald, Brian Stokes Mitchell, Debra Monk, Hattie Morahan, Donna Murphy, Kristine Nielsen, Paul Alexander Nolan, Kelli O’Hara, Patrick Page, Rachel Pickup, Taylor Richardson, Douglas Sills, Bobby Steggert, Erin Wilhelmi, John Douglas Thompson, Leslie Uggams and Merritt Wever, with Bill Camp and Phylicia Rashad.
