19 Stars You Forgot Were On 'The O.C.' From Chris Pratt to Shailene Woodley

It's hard to believe that The O.C. hit Fox over 10 years ago. The series launched the careers of stars like Ben McKenzie (who is currently starring on Fox's new Batman series Gotham ) Adam Brody, Rachel Bilson, and Mischa Barton (RIP, Marissa Cooper) but it wasn't just the leads who became uber famous after their time on the show. These X actors also made it big — though you may have forgotten they were ever on The O.C. to begin with.
