This episode, the boys are joined by Gregory Maguire, author of the original Wicked novel, its series of world-building sequels and its newest installment, “Elphie: A Wicked Childhood.” Together, these three Sentimental Men chat about Gregory’s initial reactions to the musical, the second (and third) life that the musical has given his novel and how visiting the set while they filmed the Ozdust scene gave him a new appreciation for actors on film. PLUS, the boys try to convince him that he needs to do a stint playing the Wizard on Broadway.
