Seth's goal was to attend Brown University, but he ends up going to Rhode Island School of Design (RISD) and continuing work on his comic book Atomic County.
The role saw Brody win four Teen Choice Awards from five nominations, from 2004 to 2006.
Seth is very sarcastic and uses irony to find the humor in the events that occur around him.
He has a positive nature, and although sometimes his humor is misconceived as ill-mannered, he tries to joke his way out of sticky situations and is more likely to laugh off the negatives and be overwhelmingly enthusiastic about the positives in his, and everyone else's, life.
Brody did not immediately get the part of Seth Cohen after his first audition because he improvised the dialogue.
However, the producers called him back a month later for another test, and he was cast in March 2003.
Seth is a very bubbly character, thanks to the likes of his "only true friend" Ryan, and is prone to not knowing when to keep his mouth shut, however this is more endearing and humorous, than irritating.
It was as much Seth's choice not to fit in, as it was the Water Polo players rejecting him, and a lot of that came from Brody, as well as a love for Death Cab for Cutie.
