At the ADV Films panel at Metrocon 2004, David Williams said the sparseness of news was because all information released on the project was agreed to be approved by all three parties involved: Gainax, WETA, and ADV. He did say the movie is moving ahead fine. They are currently working on script treatments and are down to a shortlist of directors. In a separate interview, Williams said that there has been no decision made yet as to whether the film will encompass the entire story of Evangelion or just the beginning.
