Seinfeld cast: Where are they now?

Jerry Seinfeld can look back at Seinfeld as just one chapter in a long, successful career. After the show ended in 1998, he continued writing, acting, and, of course, doing stand-up. In 2004, he produced The Seinfeld Story, a TV movie documentary, before he later joined the rest of the cast on a Curb Your Enthusiasm-sponsored Seinfeld reunion in 2009. From 2010 to 2011, Seinfeld served as a writer on The Marriage Ref, before launching his online series, Comedians in Cars Getting Coffee.

He continued writing with penning his 2020 book, Is This Anything?, which he described to EW as a "written document of my work, for whatever value it might have to other young comics." The same year, Seinfeld released his first original stand-up routine since 1998 for his Netflix special, 23 Hours to Kill, and later went on to tour his comedy shows.

Since her Seinfeld days, Julia Louis-Dreyfus has worked on multiple television series, from Watching Ellie to Arrested Development, The Simpsons, Web Therapy, and, in 2006, The New Adventures of Old Christine. She won six consecutive Emmys for Lead Actress in a Comedy Series for her role as Selina Meyer on HBO's Veep. Broadening her horizons, Louis-Dreyfus also joined the Marvel Cinematic Universe as Valentina Allegra de Fontaine in 2021, earning credits for The Falcon and the Winter Soldier, Black Widow (2021), and Black Panther: Wakanda Forever (2022).

Much of Jason Alexander's post-Seinfeld life involves varied guest stints on television shows, such as Friends, Malcolm in the Middle, Monk, and more. The actor joined his former costars on Curb Your Enthusiasm in 2001 and 2009, and he played recurring roles on Young Sheldon and The Marvelous Mrs. Maisel. Alexander has also delved into voice work, lending his voice on animated series like TripTank, Kody Kapow, Harley Quinn, and more.

Two years after the end of Seinfeld, Michael Richards starred in The Michael Richards Show for seven episodes before it came to an end. Sadly, however, Richards is best-known for going on a racist rant at a comedy club in 2006. Yet, since then, he has appeared in a 2012 episode of Comedians in Cars Getting Coffee; starred on Kirstie from 2013 to 2014; and appeared in the Christian film Faith, Hope & Love (2019).

Aside from his voiceover work, Knight could be seen as Officer Don on 3rd Rock from the Sun after Seinfeld. Since then, he's stayed consistently busy, appearing on The Exes, Law & Order: Special Victims Unit, and The Truth About the Harry Quebert Affair, as well as in films like 12 Mighty Orphans (2021), Darby and the Dead (2022), and more. In addition to those onscreen credits, Knight also reprised his Seinfeld role in a 2020 anti-Trump ad.

Swedberg had brief appearances on a number of shows following her time in Seinfeld, from Roswell to ER to Gilmore Girls. She was last seen as Olivia Maxwell on HawthoRNe in 2010.

In 2001, Warburton took on the role of the Tick on the TV series, which only lasted one year. He then went on to play Jeb Denton on Less Than Perfect from 2003 to 2006, followed by a long run as Jeff Bingham on Rules of Engagement from 2007 to 2013. Warburton also continued with his voice work, including roles as Kronk in The Emperor's New Groove (2000), Brock Samson on The Venture Bros., and Joe Swanson on Family Guy. On screen, the actor appeared in Ted (2012) and it's 2015 sequel and played Lemony Snicket on Netflix's A Series of Unfortunate Events from 2017 to 2019.

O'Hurley has filled most of his time with voice work, voicing Walter Bunny on The Looney Tunes Show, Roger Doofenshmirtz on Phineas and Ferb, and King Neptune in the SpongeBob SquarePants franchise. O'Hurley is possibly best known post-Seinfeld as host of Family Feud from 2006 to 2010.

Cranston found huge TV success following his time on Seinfeld, playing Hal on Malcolm in the Middle for six years before taking on his award-winning role as Walter White (who he reprised on Better Call Saul in 2022) on Breaking Bad for five seasons. He then scored the lead role as Michael Desiato on Showtime's Your Honor. However, Cranston has also conquered the big screen with features like Why Him? (2016), The Upside (2017), Isle of Dogs (2018), and Jerry and Marge Go Large (2022). On stage, Cranston has earned Tonys for his work in Broadway's All the Way and the National Theatre's Network.

After appearing in the first two seasons of Seinfeld, Woodburn went on to guest-star on a variety of shows, including Charmed, Passions, Bones, The Bold and the Beautiful, and Station 19. The actor also voiced Splinter in the 2014 big-screen remake of Teenage Mutant Ninja Turtles, and joined former costar Alexander in 2020's Faith Based. 

After leaving Seinfeld, Jerry Stiller later become known for his role as Arthur Spooner on The King of Queens, which ran from 1998 to 2007. He then spent a year as Principal Sticker on the TV series Fish Hooks. Stiller appeared in several films like Hairspray (2007) and Zoolander No. 2 (2016) before he died of natural causes in 2020.

Harris' best-known role is arguably as the voice of Mrs. Potato Head in the Toy Story films. She also appeared as Muriel on The Suite Life of Zack and Cody. Sadly, however, the actress died from natural causes in 2022.

After Seinfeld, Martin was only involved in three projects before his death: He played a role in the television movie I Married a Monster (1998) before voicing Ambassador Major on the series Buzz Lightyear of Star Command, and finally, he appeared as Maury in the 2004 series Center of the Universe. In 2005, he died of cancer at age 82.

Sheridan appeared on a few television series following Seinfeld, including Complete Savages and Numb3rs, before voicing Mrs. Rothberg in an episode of American Dad! in 2007. She also starred in the 2009 Marc Fienberg film, Play the Game. Nevertheless, Sheridan died from natural causes in 2022.
