Seth Rogen

Seth Rogen was the young co-star of a critically-acclaimed but short-lived TV series, and now he's the star of the 2007 comedy hits Knocked Up (with Katherine Heigl) and Superbad (with Christopher Mintz-Plasse). A teenage comedian from Vancouver, B.C., Rogen got his big break in the 1999 Judd Apatow series Freaks and Geeks, along with cast members Linda Cardellini and James Franco. After the show was cancelled Rogen had some small movie roles (including in the 2001 Jake Gyllenhaal movie Donnie Darko) and followed Apatow to the series Undeclared (2001-02). Rogen served as an actor and a writer for the show, and from there he went to the writing staff of Da Ali G Show (2003-04, starring Sacha Baron Cohen). A well-received supporting role in The 40 Year Old Virgin (2005, starring Steve Carell) proved the popularity of his curly-and-burly, guy's guy persona, and Apatow wrote Knocked Up specifically for Rogen. He has also appeared in Anchorman: The Legend of Ron Burgundy (2004, starring Will Ferrell) and You, Me and Dupree (2006, with Owen Wilson).
