The Wizard of Oz is a 1939 American musical fantasy film directed primarily by Victor Fleming from a script mostly by Noel Langley, Florence Ryerson and Edgar Allan Woolf, with uncredited contributions by others. Made and released by Metro-Goldwyn-Mayer, it was based on the 1900 novel The Wonderful Wizard of Oz by L. Frank Baum, who died twenty years before the film was released.
Father Lawrence Mazzare owned a tape of The Wizard of Oz. While talking with Reverend Simon Jones over witch trials, Mazarre jokingly lament the fact that the Catholic Church think every woman is the 'wicked witch of the west' and wished they could change their mind after thinking about Glinda the Good Witch instead. Upon hearing this Jones mentioned Mazzare's copy of The Wizard of Oz and suggested on showing it on Grantville's television network that could curb the witch hunt hysteria. Mazzare agreed as it only works inside the New United States.
