In 1926, Dreyer was invited to France to make a film. He mentioned three subjects of interest: Marie Antoinette, Queen of Louis XVI, Catherine Medici, Queen of Henry II, and Joan of Arc . Finally, he chose to adapt the story of Joan of Arc. In order to devote himself to creation, Delaier's family moved to Paris and began the preliminary data collection for about a year and a half. Since Joan of Arc was chased as a Catholic saint in 1920, France set off an upsurge in studying Joan of Arc. But Delaire was dissatisfied with the material he saw, including the novel with Joan of Arc as the protagonist. He looked up after the trial of Joan of Arc was captured and burned at the stake in the library of original records file, which contains 29 times the interrogation of words
.
After being thoroughly familiar with the trial materials, Delaire believes that the trial contains all the elements of Joan's life, so the film should focus on the trial, which is not a distortion of history, but a dramatization of history. He decided not to make a historical film that focused on the big scenes and massacres, but instead focused on the spiritual pursuits that Joan of Arc experienced during the trial. He hopes that the audience can learn about Joan through his films, experience her, integrate into her unfortunate world, and feel her fear and pain. Therefore, he concentrated 29 times in the history of the trial of Joan of Arc is among the last five times a day in the life of the trial, her trial is limited to the location of the city fort
