"We went back to the theme of nuclear weapons, since that was the theme of the original film. Japan has now learned three times what a nuclear disaster is, but at that time Japan had already had two. The problem was Japanese society was gradually forgetting about these disasters. They were forgetting how painful it had been. Everyone in Japan knew how scary nuclear weapons were when the original movie was made, but it wasn't like that by the 1980s. So in those meetings, we decided to remind all those people out there who had forgotten."
