What's the Deal With the ‘Seinfeld’ Cast? Here's Where They Are Now

When it premiered in 1989, Seinfeldbroke conventional sitcom formulas by focusing on the minutiae of everyday life—waiting for a table, losing a sock, crossing a street. But despite being brilliantly written by Larry Davidand Jerry Seinfeld, the so-called “show about nothing” wouldn’t have worked were it not for its stellar cast, including Seinfeld as straight man Jerry, Jason Alexander as neurotic George, Julia Louis-Dreyfus as outspoken Elaine and Michael Richards as harebrained Kramer.

Seinfeld Cast: Where Are They Now?

Jerry Seinfeld as Jerry Seinfeld

Like his character, Seinfeld was a stand-up comedian when he co-created the show. The idea came about after NBC and Castle Rock Entertainment approached him to do a special, and he enlisted his friend Larry David for a brainstorm. The pair came up with the concept of Seinfeld in the spring of 1988, "at the Westway Diner at Ninth and 44th Street...over the usual late-night comedy coffee," Seinfeld told The New York Times in 1991. 

Since wrapping the series, Seinfeld has continued doing standup—the DNA of his career—including a residency at New York’s Beacon Theater that’s been ongoing since 2016. “...My comedy is in the cracks,” he told The New York Times more than three decades ago. “I talk about the fascination of moments in between the ones that people talk about." That remains true to this day. 

Standup aside, Seinfeld has also starred in, co-written and produced 2007’s Bee Movie, and created the 2012 Netflix talk show Comedians in Cars Getting Coffee, in which he chats with famous friends like Tina Fey while driving around in vintage cars (and, yes, they stop for coffee). The show ran for 11 seasons. 

Most recently, Seinfeld directed, co-wrote and starred in the 2024 Netflix comedy Unfrosted, which is loosely based on the creation of the Pop-Tart.

On the personal front, he’s been married to Jessica Seinfeld since 1999, and they share three children: Sascha, born in November 2000; Julian, born in March 2003; and Shepherd, born in August 2005.

Julia Louis-Dreyfus as Elaine Benes

Louis-Dreyfus’s pre-Seinfeld credits included three years on Saturday Night Live (1982-85) and small roles in a handful of movies, including Hannah and Her Sisters and National Lampoon’s Christmas Vacation. She also starred in the short-lived series Day by Day as a sarcastic neighbor to a couple who opens a daycare out of their home. 

When David sent her the scripts for Seinfeld, she recalled in conversation with entertainment journalist Jess Cagle, “I thought, Ooh, this is so not like anything on television. It was not written like a sitcom. It wasn’t setup-punch, setup-punch, you know? So I thought, Ooh, this seems cool, and it’s Larry, and he’s so weird, and that feels good.” She met with David and Seinfeld, who cast her as Elaine, but because NBC had only given the show a four-episode order, she didn’t think too much of the opportunity.

“It’s not like anybody thought, We’re onto something huge here. It was four episodes.” Cut to 1996, and she was taking home an Emmy for her role on the series. 

Impressively, she followed Seinfeld up with two more hit series, CBS’s The New Adventures of Old Christine (2006-10) and HBO’s Veep (2012-19), both of which earned her more Emmys, making her the first actress to take home the award for three different shows. 

She’s also popped up on series like Web Therapy, Curb Your Enthusiasm and Arrested Development, and she's starred in movies including Nicole Holofcener’s Enough Said (2013) and Kenya Barris’s You People (2023).

In September 2017, after winning her sixth consecutive Emmy for her role in Veep, Louis-Dreyfus publicly revealed that she had breast cancer. A year later, she shared that she was cancer-free. 

“When you’re younger, there’s kind of this arrogance of youth...You do feel immortal,” she told Hoda Kotb on Today in 2024. “And then all of a sudden, you’re bumped up against that, and you're like, ‘Oh, wait a minute, this at some point it’s going to end. What?’ You know, you don’t go through life thinking about that very much, so it puts into sharp focus priorities. It did for me.”

Jason Alexander as George Costanza

Alexander was a theater actor with a handful of commercials, a slasher flick (The Burning), and two short-lived shows (E/R and Everything's Relative) under his belt when he auditioned for Seinfeld. "They called a casting director and said, 'Just put some theater actors on tape,’” he told Howard Stern.

“It read like a Woody Allen film,” he recalled of the script (he received just a few pages). “I had no context for it, so, hence, I did the glasses and as blatant a Woody Allen as I could do.” (In reality, the character of George was inspired by Larry David himself.) "...I made the tape, and I went, ah, that's just an exercise in nothing. Then a couple weeks later, [I] got a call from NBC." He met with Seinfeld, and the rest is history. 

Since Seinfeld, Alexander has guest-starred on a variety of shows, including Curb Your Enthusiasm, Two and a Half Men, Community, Young Sheldon and The Marvelous Mrs. Maisel. He’s also returned to his theater roots, starring in a Fish in the Dark in 2015 and made his directorial debut with The Cottage in 2023.

Michael Richards as Cosmo Kramer

In the foreword to Richards’ 2024 memoir, Entrances and Exits, Seinfeld wrote that despite NBC requiring a lengthy audition process, “no one else stood a chance” for the role of Kramer. Richards went on to win three Emmys for his iconic role—more than any of his castmates in the historic comedy series.

Following Seinfeld, he starred in seven episodes of The Michael Richards Show before it was canceled, but his career stalled after he yelled a racial slur at an audience member during a comedy show in 2006. 

"I was immediately sorry the moment I said it onstage," Richards told People while promoting his 2024 memoir. But, he added, "I'm not looking for a comeback." 

"[I'm] learning and healing. Healing and learning," he added later. "But life is always an up and a down. I continue to work through the day and the night, the light and the dark that I am."

Wayne Knight as Newman

Knight joined the show as Jerry’s arch-nemesis, Newman, in 1992, at which point he had already had supporting roles in movies like Dirty Dancing and Basic Instinct.

“I came in, did the audition, got the job for the one-off of Newman,” he told The AV Club, explaining that he initially wasn’t meant to be a recurring character. “...They’d created this idea of this guy who was kind of like the building snitch. Originally, the plan was that he was the landlord’s son or nephew and he was a snitch.”

Knight wound up appearing in 44 episodes of Seinfeld while also booking roles in Jurassic Park and 3rd Rock from the Sun, on which he starred in more than 100 episodes. His career has been every bit as busy since Seinfeld wrapped, with roles in Hot in Cleveland, TV Land’s The Exes and more. He also made a recent appearance in the hit movie, Five Nights at Freddy's 2.

Jerry Stiller as Frank Costanza

Stiller, who rose to fame in the 1960s alongside his wife, Anne Meara, through appearances on The Ed Sullivan Show, was a comedy legend by the time he was cast as George’s dad on Seinfeld. And his career was far from over after the series ended—he went on to star in The King of Queens, Zoolander (alongside son Ben Stiller) and more. He died in May 2020 at the age of 92.

Estelle Harris as Estelle Costanza

Harris broke out in her late 60s when she joined the cast of Seinfeld in 1992. Up until then, she’d been a community actress and commercial talent with a handful of recurring TV performances. Following the show, her late-in-life career continued to blossom, with voice roles in the Toy Story movies, Kim Possible, Dave the Barbarian and more. She died in April 2022 at the age of 93.

Barney Martin as Morty Seinfeld

Martin, who got his start in film when Mel Brooks featured him in The Producers in 1967, said at Seinfeld's wrap party in 1998 that "playing Jerry's dad was like having whipped cream on top of a mountain of ice cream."

Prior to joining the series, he starred in Broadway musicals like All American and How Now Dow Jones, and he created the role of Amos Hart in the musical Chicago. Alas, he didn't act much more after the show ended, and he died in March 2005 at the age of 82.

Liz Sheridan as Helen Seinfeld

Throughout the 1980s, Sheridan took on supporting roles in shows like Kojak, Moonlighting, St. Elsewhere and Family Ties, but her breakout came when she was cast as the nosy neighbor on ALF, which she followed up with the role of Jerry's mom on Seinfeld.

In 2000, she released her memoir Dizzy & Jimmy: My Life With James Dean, which recounted her love story with the late actor. She died in April 2022 at the age of 93. Reacting to her death, Seinfeld said in a statement, "Liz was always the sweetest, nicest TV mom a son could wish for. Every time she came on our show, it was the coziest feeling for me. So lucky to have known her."
