Carl Th. Dreyer's script for the Jesus film is now online. See the manuscript in English for Jesus of Nazareth on the Dreyer website.
For more than 30 years, up to the time of his death, Dreyer intensely worked on his Jesus film. He had completed a script as early as 1950. A contract Dreyer signed with a wealthy American, Blevins Davis, who agreed to produce the film, proved fatal. The Jesus film was never realised.
