Actor Clark Duke entered the professional acting sphere during childhood, with an ongoing role as Elliot Hartman, one of two sons of congressional legislative assistant John Hartman (John Ritter, whom Duke resembled), on the popular CBS sitcom Hearts Afire (1992-1995). Thereafter, Duke took nearly a decade off to pursue his studies, but received renewed attention years later thanks to an off-camera friendship and professional partnership with the popular comedic actor Michael Cera (Arrested Development). That association began when Duke appeared alongside Cera in the Judd Apatow-produced, Greg Mottola-directed sex comedy Superbad, and continued via the pair's creation of the successful web series Clark and Michael. The program, done in an extremely dry, put-upon mockumentary style that recalled both The Office and Arrested Development, starred the actors as themselves, and depicted their adventures attempting to break through the impenetrable walls of show business. It drew a substantially large fan base and became something of a cult hit. Thereafter, Duke starred in the popular frat-boy-themed series Greek (2007) and signed on as one of the leads in the big-screen teen sex comedy-road movie Sex Drive (2008). Over the next several years, Duke would also appear in a number of big screen comedies, like Sex Drive, Kick-Ass, Hot Tub Time Machine, and A Thousand Words.
