Seth Rogen (born April 15, 1982 in Vancouver, British Columbia, Canada) got his start in show business at age 13 after signing up for a comedy class. With his trademark deadpan humour, he went on to win the Vancouver Amateur Comedy Contest at 16, then headed south of the border to continue stand-up and acting. Rogen snapped up his first starring role in the Judd Apatow/Paul Feig 1980s-set teen series Freaks and Geeks (1999-2000) with only two auditions. He played cynical, ascerbic "freak" Ken Miller. After the show was canceled in the middle of its first season, Rogen was cast in a similar role in Apatow's second, also short-lived series, Undeclared (2001-2002), and went on to write several episodes.
He has also written for Da Ali G Show and had minor roles in Donnie Darko and Dawson's Creek.
Rogen returned to the big screen in the 2005 Judd Apatow comedy The 40-Year-Old Virgin, and the director has plans to cast his protégé in a leading man role in a future film.
