For the past decade bookstores and movie theaters have been Rowling this, Radcliffe that. But a new word sorceress has emerged from the darkness. So now, let there be Twilight. Stephanie Meyer's teenage vampire saga is already a mega-success (the third installment knocked Harry from the number one spot, the final one is released next month), and studio execs are hoping this bloodlust trickles into theaters, when the adaptation hits screens this December. So high is the anticipation, that Entertainment Weekly just featured the film on its cover, officially launching Twilight mania. In a refreshingly candid interview, Michael Welch, one of the film's young stars, reveals how he was cast in the film, why if it tanks it's not his fault, and the big secret behind the acting business.
