 Early in the production of the musical , the president of the Church of Scientology in New York sent a letter to the producer pointing out the Church 's history of litigation . This led Timbers and Jarrow to insert the word " Unauthorized " into the title , upon the advice of legal counsel . During the Los Angeles production , representatives of the Church of Scientology visited the production staff in the midst of rehearsals and handed out documentation of successful litigation against critics of Scientology . Parents of some of the Los Angeles cast members also received phone calls from Scientologists in the entertainment industry , asking them not to allow their children to perform in the musical .
