Sometimes it's a fine line between where a character ends and the actor begins.

This is true for Adam Brody (search), who plays Seth Cohen on Fox's latest drama "The O.C." (search

"As the show goes on, Seth is becoming more like me and that's from Josh [Schwartz, creator/writer] knowing me and writing it more to me, and me looking at it at and making it more like me," said 23-year-old Brody, of his nerdy-yet-cool "misfit" character.

"I like to think that I'm a little steadier on my feet with girls, but other than that, we're into the same things, even clothing - sometimes the other cast asks if I'm dressed when we're rehearsing the scene."

Other elements of Brody's personality that have been written into the show include Seth being a "comic book nerd," last night's reference to one of Brody's "all-time favorite bands," Death Cab for Cutie, and his penchant for saying "uh" and "dude."

"I say 'uh' a lot and that's in all my speeches. I say 'dude' way too much - they write that in for me a lot, but a lot of times that's just me not being able to help myself," Brody said.

Off set, the differences are more obvious: Brody plays drums in his self-described "wannabe indie rock - really bad Weezer" garage band, drinks a lot of coffee, surfs and watches almost every movie out.

(Seth sails, but does have a strange obsession with the IMAX Experience.)

Many viewers probably recognize Brody from his season-long stint as Lane's boyfriend on "Gilmore Girls," (search) where "they make you talk faster.

"I talk pretty fast normally, but it's nice - the luxury of being able to take a breath," says Brody.

Since its premiere on Aug. 5, ratings for "The O.C." have steadily climbed and its growing popularity hasn't escaped the cast.

"It's really weird to have it go from 0 to 60 as fast as it did and to all of a sudden step out and have people say: 'Hey, 'The O.C.,' love it man,' " says Brody.

"I was reading 'Entertainment Weekly' and Conan O'Brien (search) was talking about his future and he said something like 'who knows, maybe in five years I'll be living in a pool house on "The O.C.," ' and I thought 'Oh my God, it's pop culture now, it's officially out there.' "

When the show returns on Oct. 30, to its new timeslot on Thursdays at 9 p.m., Brody reveals that Anna comes back when school starts and "I get my little love triangle - get to finally have two girls, fightin' for Seth."
