The last time many viewers saw Dominic Chianese, his legendary Sopranos alter ego, Corrado "Junior" Soprano, was languishing with senile dementia in a rest home. This fall will find him substantially more compos mentis in the second season of HBO's Boardwalk Empire, which premieres September 25. According to the show's creator/executive producer (and fellow Sopranos alum) Terrence Winter, Chianese will guest in six of the season's 12 episodes as one Leander Whitlock, whom Winter describes as a contemporary of Dabney Coleman's Commodore. "He's almost unrecognizable," says Winter of Chianese's appearance. C'mon, we'd know that mug anywhere!
