When James Marsters moved to Hollywood, he told his agent he didn't care if he became the "new Urkel."A classically trained Shakespearean actor, Marsters, 53, was happy with being a poor theater actor. But his priorities changed when his son, Sullivan, was born in 1996."I came to Hollywood to whore myself out," Marsters says, of Los Angeles, who's appearing at the Motor City Comic Con, Friday, May 13, through Sunday, May 15, in Novi.
