the novel. Holzman observed in an interview with Playbill that: "It was [Maguire's] brilliant idea to take this hated figure and tell things from her point of view, and to have the two witches be roommates in college, but the way in which their friendship develops—and really the whole plot—is different onstage." Schwartz justified the deviation, saying: "Primarily we were interested in the relationship between Galinda—who becomes Glinda—and Elphaba... the friendship of these two women and how their characters lead them to completely different destinies." Other major plot modifications include Fiyero's appearance as the scarecrow, Elphaba's survival at the end, Nessarose using a wheelchair instead of being born without arms, Boq having a continuing love interest for Glinda and eventually becoming the Tin Woodman instead of Nick Chopper, cutting Elphaba's years in the Vinkus, the deletion of Liir's birth, Fiyero not having a wife and children, Doctor Dillamond being fired instead of being murdered, and Madame Morrible going to prison instead of dying. The book, lyrics, and score for the musical were developed through a series of readings. In these developmental workshops, Kristin Chenoweth, the Tony Award–winning actress whom Schwartz had in mind while composing the music for the character, joined the project as Glinda. Stephanie J. Block played Elphaba in the workshops (she played Elphaba in the first national tour and later as a Broadway cast replacement) before Idina Menzel was cast in the role in late 2000. Earlier that year, the creators recruited New York producer Stone, who began planning the Broadway production. Joe Mantello was engaged as director and Wayne Cilento as choreographer, while designer Eugene Lee created the set and visual style for the production inspired by W. W. Denslow's original illustrations for Baum's novels and Maguire's concept of the story being told through a giant clock. Costume designer Susan Hilferty created a "twisted Edwardian" style in building more than 200 costumes, while lighting designer Kenneth Posner used more than 800 lights to give each of the 54 distinct scenes and locations "its own mood." By April 2003, the show was in rehearsals. Following the out-of-town tryout in San Francisco in May and June 2003, which received mixed critical reception, the creative team made extensive changes before its transfer to Broadway. Holzman recalled: Stephen [Schwartz] wisely had insisted on having three months to rewrite in between the time we closed in San Francisco and when we
