Casting for the upcoming Revenge of the Nerds remake (or re-imagining) is heating up, and we now know who will be playing the main nerds. IESB reports Chris Marquette, Dan Byrd, and Efren Ramirez have signed on as members are the Lamda Lamda Lamda fraternity, with Marquette and Byrd playing the lead roles. They also tell us Kristin Cavallari will be joining Katie Cassidy as Kailey, best friends and sisters in the Pi Delta Pi sorority.

This marks Marquette's second time working with director Kyle Newman, as the two also paired up on Fanboys. He'll be taking on the part of Max Foster, lead nerd. Byrd will play his sidekick, Owen DiMarco (aka "horn dog"), the kind of guy who majors in women's studies. Not surprisingly, Ramirez will portray a foreign exchange student (a la Napoleon Dynamite) named Santiago. In a recent interview with Coming Soon, Ramirez noted his accent will be "quite like Mr. Deeds' John Turturro with the personality of Raul Julia in The Addams Family." Okay, that sounds a bit bizarre ... but I dig it. When asked whether any of the nerds will be based off characters from the original film, Ramirez replied, "They're all new."

So, what do you think about the new cast? Any chances they'll screw it up?
