- "The O.C." aired on Fox for four seasons between August 2003 and February 2007.
- The teen drama starred Ben McKenzie, Mischa Barton, Adam Brody, and Rachel Bilson.
- Here's what the cast has been up to in the years since, from more acting jobs to writing books.
Ben McKenzie starred as Ryan Atwood, a 17-year-old from a broken home in Chino, California.
The series kicked off with Ryan getting caught stealing a car with his older brother, Trey (played by Logan Marshall-Green).
After getting sent to juvenile detention, Ryan met a public defender named Sandy Cohen, who eventually took him into his home and let him become part of his family.
McKenzie released a book about cryptocurrency, titled "Easy Money: Cryptocurrency, Casino Capitalism, and the Golden Age of Fraud."
The subject matter of McKenzie's book isn't too bizarre, considering that he has a degree in economics from the University of Virginia and had been vocal about his disdain for cryptocurrency (and the celebrities who support it) in recent years.
Aside from playing Ryan Atwood on "The O.C.," McKenzie is perhaps best known for starring as Jim Gordon on Fox's "Gotham," which centered on the young Bruce Wayne/Batman's origin story. The show lasted for five seasons between 2014 and 2019.
While on "Gotham," McKenzie made his directorial debut and wrote the scripts for two episodes of the series.
McKenzie has been married to "Gotham" costar Morena Baccarin since 2017. They share a daughter named Frances (born in 2016) and a son named Arthur (born in 2021).
Coincidentally, Morena guest-starred on "The O.C." but the two actors didn't connect at the time.
Mischa Barton played Marissa Cooper, a teen who became increasingly unstable as the show went on.
Marissa tragically died in Ryan's arms on the season three finale, which aired in May 2006.
Barton starred on season one of the reality TV show "The Hills: New Beginnings."
The "Hills" revival series lasted for two seasons on MTV, but Barton didn't return for the latter season.
After Marissa was shockingly killed off "The O.C." fans wondered about the reasoning behind Barton's exit. Show creator Josh Schwartz told The Daily Beast in 2017 that ratings pressure from the network was one factor that led to the decision to kill off Marissa.
"It was a complicated chemistry with the cast," he added. "But she certainly wasn't actively seeking to leave the show."
In a 2021 interview with E! News, Barton spoke candidly about her experience on the show and said that she faced "general bullying from some of the men on set that kind of felt really shitty."
"There were people on that set that were very mean to me," she said. "It wasn't, like, the most ideal environment for a young, sensitive girl who's also been thrust into stardom to have to put up with."
Barton also opened up about the challenges of being in the public eye, beginning with feeling sexualized as a child actor, in a 2021 essay for Harper's Bazaar. The star said that she was stalked by paparazzi and often felt unsafe, leading to PTSD.
The actor was arrested for DUI and driving without a valid license in December 2007. Months later, she was charged with a misdemeanor DUI and pot possession. In a 2008 cover story for Nylon, she said that getting arrested was "a lot point" for her.
Barton continued to act, with roles on shows like "Law & Order: Special Victims Unit" and "The Beautiful Life."
In 2016, she competed on season 22 of ABC's "Dancing With the Stars."
Barton has since starred in dramas like "Deserted, "Painkillers," and "Ouija House."
Adam Brody portrayed the show's sarcastic, comic-book-loving teen named Seth Cohen.
He was socially awkward and loved bands like Death Cab for Cutie.
Despite being part of the upper-middle class, Seth despised living in Orange County and wanted to leave.
Brody now plays a superhero in the DC Extended Universe.
The actor played the adult alter ego of Jack Dylan Grazer's Freddy Freeman in the "Shazam!" films released in 2019 and 2023. Coincidentally, Seth Cohen and Freddy Freeman both have extensive knowledge of comic books.
After "The O.C." Brody continued appearing in films and shows.
This included the cult classic "Jennifer's Body," "Scream 4," and the 2011 film "The Oranges," which costarred his future wife, Leighton Meester.
He also guest-starred on season three of the hit sitcom "New Girl" and starred on the show "StartUp."
Brody and Meester went on to costar in the 2014 movie "Life Partners." The "O.C." alum also had a recurring role on her show "Single Parents."
In more recent years, Brody starred in the horror movie "Ready or Not" and Emerald Fennell's "Promising Young Woman."
He also had a voice cameo in the 2022 "Scream" movie and played Seth Morris on season one of the Hulu/FX miniseries "Fleishman Is in Trouble."
Brody has been married to Meester since 2014. He and the "Gossip Girl" star have two kids, a daughter named Arlo Day (born in 2015) and a son (born in 2020) whose name they haven't disclosed.
Rachel Bilson portrayed Summer Roberts, Marissa's best friend.
Bilson was originally cast as a guest star on "The O.C." but her performance impressed show creator Josh Schwartz and she became a series regular.
Bilson and Brody dated in real life from 2003 to 2006 and remain on friendly terms to this day.
Bilson cohosts the podcast "Broad Ideas" with her long-time friend Olivia Allen.
The wide-ranging podcast covers a variety of topics, from sex and relationships to mental health and career challenges. Past guests have included Lucy Hale, Chace Crawford, and Aubrey Plaza.
Bilson also cohosted an "O.C." rewatch podcast with costar Melinda Clarke.
Following her role on "The O.C." Bilson starred alongside Hayden Christensen in the 2008 sci-fi movie "Jumper." The actors dated in real life, welcoming a daughter named Briar Rose in 2014. They split in 2017, after being together for almost a decade and previously calling off their engagement.
Bilson also had a cameo on the series finale of the original "Gossip Girl" series and guest starred on a few episodes of "How I Met Your Mother," as the roommate of the titular mom.
She later starred on the CW series "Hart of Dixie" and had a recurring role on season five of the show "Nashville."
Most recently, Bilson appeared on the Fox anthology series "Accused."
Peter Gallagher starred as Sandy Cohen, a public defender and the father of Seth.
Sandy grew up in a rough part of the Bronx, with little money.
Gallagher starred as Andrew Finney on season three of the Apple TV+ drama series "Truth Be Told."
In the years since "The O.C." Gallagher has appeared in an array of shows and movies. This includes series like "Californication," "How I Met Your Mother," "New Girl," and "The Gifted."
He also had roles on "Grey's Anatomy" and "Grace and Frankie."

The show ran for three seasons between 2012 and 2015.

The actor also welcomed her first child, a daughter, the year after "The O.C." ended.
Tate Donovan portrayed Jimmy Cooper, Marissa's dad.
At the start of the series, Jimmy was a financial planner who lost $4 million and was the subject of an SEC fraud investigation.
Donovan played Chris Evans' on-screen dad in the 2023 action movie "Ghosted."
Donovan's "O.C." character became less prominent on the show beginning with season two. The next season, he appeared in just three episodes and made his directorial debut.
Donovan returned as a guest star in the final season, as part of an alternate reality episode.
Donovan went on to continue acting and directing after "The O.C." He directed episodes of TV shows like "Gossip Girl," "Glee," "Madam Secretary," and "Hawaii Five-0."
You may have seen the actor in films like "Argo," "Manchester by the Sea," and "Rocketman."
He also guest-starred on TV shows including "Elementary," "Law & Order: Special Victims Unit," and "MacGyver."
Additionally, Donovan is the recipient of a 2014 Emmy Award, for his work as a producer on "30 for 30 Shorts."
Melinda Clarke played Julie Cooper, Marissa's mom.
She was superficial and had expensive taste, which didn't bode well when Jimmy experienced financial hardships.
Clarke and Bilson cohosted the "O.C." rewatch podcast called "Welcome to the OC, Bitches!"
On the podcast, which launched in 2021, Clarke and Bilson shared behind-the-scenes secrets from the show and interviewed cast and crew members.
