The thinking man's nerd, Adam Brody so inhabited the charm of the neurotic Seth Cohen on "The O. C." (Fox, 2003-07), that many believed he was simply playing a version of himself, so completely did he nail the character. Fans of both sexes admired the actor's unmistakable cool vibe, but they also worshipped his knowledge of the underground music scene and comic books. The idea of "geek" suddenly became "chic," with Brody the crown prince of a new idea of teen spirit. So beloved was the actor, that when he and his "O.C." co-star Rachel Bilson broke up after a long-term courtship, there was a genuine feeling of sadness, as the adorable twosome had seemed so real and un-Hollywood like. After the show's inevitable cancellation in 2007, Brody seemed the best bet - from a cast that included Bilson, Mischa Barton and Benjamin McKenzie - to make the jump to movie stardom. He had shone in small parts in hit films like "Mr. and Mrs. Smith" (2005) and "Thank You for Smoking" (2006), before landing a lead role in the female-centric romantic comedy, "In the Land of Women" (2007), more than holding his own onscreen opposite Meg Ryan. While a career as a successful leading man did not pan out, he remained a welcome presence as a character actor in both comedies and dramas.
