However, the director decided that it would be better to make the movie in Japan where the cultural aspects of the setting would enrich the story. Therefore, he took the project to the Japanese movie companies after which production began. The high school setting in the original story was changed to an international school for the movie and apart from the staff and cast everything concerned with filming the movie used Japanese methods. This meant that the movie contained approximately a quarter of the English conversation as was in the original story.The release date for the movie was not disclosed for a long time following the announcement that it was to be produced.
