In August 2003, the words "Welcome to the O.C., b----" lifted the curtain on the elusive world of the West Coast elite, where designer bikinis were the dress code and drama was always on the guest list.
The O.C.ran for four seasons — airing 92 episodes from its 2003 premiere through February 2007 — following Ryan Atwood (Ben McKenzie), a troubled teen from Chino who moved to Newport Beach to live with his public defender's family. Friendships and romances blossomed on the Fox series as its young cast was thrust into the spotlight.
See how the rest of the cast, includingMischa Barton,Adam BrodyandRachel Bilson, have changed since their time spent in Orange County.

Mischa Barton as Marissa Cooper
The girl next door wore Chanel on The O.C., where Barton played SoCal sweetheart-meets-damsel-in-distress Marissa Cooper until her character's tragic death in season 3. Barton would later claim that she departed the series because of "bullying" behind the scenes.
When It girl Barton left The O.C., her career took a backseat to her partying ways, leading to a 2007 DUI arrest and a 2009 suicide threat. She opened up to PEOPLE about her ups and downs, explaining, "It was a full-on breakdown." Barton also was involved in a high-profile revenge porn lawsuit against a former boyfriend who allegedly tried to sell a sex tape featuring Barton.
Following her departure from The O.C., Barton landed a handful of other movie and TV appearances, from the supernatural thriller I Will Follow You Into the Dark (2012) to the TV pilot Gutsy Frog. In 2016, she competed on Dancing With the Stars and made headlines once again when she joined the cast of The Hills: New Beginnings reboot in 2019, but Barton left the series after the first season. Barton continues to appear regularly in films, including 2023's Invitation to a Murder.

Rachel Bilson as Summer Roberts
Bilson melted hearts and perfected her tan as Summer Roberts, the popular girl who — you called it! — fell for the video game nerd (Brody's Seth Cohen). Off camera, Bilson and Brody took their relationship beyond the beach, dating from 2003 until 2006.
The actress' first big role post-O.C. saw her move from Orange County to Bluebell, Ala., where she played displaced New Yorker Dr. Zoe Hart on The CW's Hart of Dixie. She then headed for Nashville, where she played Alyssa Greene, and the short-lived ABC series Take Two. Her film roles include Jumper (2008), New York, I Love You (2008) and The To Do List (2013). Bilson hosts a podcast with former O.C. costar Melinda Clarke, called Welcome to the O.C., Bitches!

Adam Brody as Seth Cohen
Brody's chic geek alter ego loved all things comic books, Chrismukkah and, of course, Summer Roberts. Besides taking his love for leading lady Bilson off-screen, he also introduced the show's tween fan base to indie bands like Death Cab for Cutie.
Since finishing his comic books, Brody has taken on a variety of roles ranging from a lethal lead singer in the 2009 dark comedy Jennifer's Body to a porn star in 2013's Lovelace as well as a role in 2020's Academy Award-winning Promising Young Woman. He also got to play a superhero in 2019's Shazam! and its 2023 sequel, Shazam! Fury of the Gods. On TV, Brody has starred on series like StartUp and Single Parents and on the FX on Hulu miniseries Fleishman Is in Trouble.
Though Brody didn't sail off into the sunset with Bilson on a "Summer" breeze, he ultimately wed fellow teen soap alum/former Gossip Girl star Leighton Meester (with whom he also starred in Single Parents!). The pair have two children together: a daughter Arlo Day, born in August 2015, and a son, born in 2020.

Ben McKenzie as Ryan Atwood
Good-looking bad boy Ryan Atwood brought as much drama as the Newport housewives when he navigated his post-Chino life and tidal wave-like relationship with Barton's Marissa Cooper — all while wearing his signature white tank top.
Two years after leaving his pool house residence, McKenzie joined the LAPD as Officer Ben Sherman on Southland, which aired until April 2013. He then took on the role of detective James Gordon on Gotham and Gotham Stories until 2019.

Who got Olivia Wilde's kiss of approval on The O.C.? As Alex Kelly, she hooked up with both Seth Cohen (Brody) and Marissa Cooper (Barton), while also helping to run the local hot spot, the Bait Shop. Though Wilde only appeared in 13 episodes of The O.C., her character certainly made an impression.
