影片《A》开拍于1995年，在东京地铁发生举世震惊的“沙林事件”6个月之后。这部试图从内部对奥姆真理教进行观察的纪录影片其整个制作过程耗时两年三个月。和一些先入为主的见解相左，影片的作者并不急于得出直截了当的结论；也不同于许多新闻报道中所提供的正反两极化呈现——这种方式往往将对立的“他们”（年轻的奥姆教皈依者）和“我们”（警察、媒体、你我自己）描述得犹如一枚硬币的正反两面；在森达也的镜头前，神圣和卑劣、公正和虚伪这样一些截然对立的概念跨越了界限分明的鸿沟而交汇在了一起。该片的目的不是为了一味地去曝露那些异教徒的阴暗，而是从一种相对的视角来反观我们自身存在的暴唳和缺陷，你的，和我的，从而进一步找到人性中黑暗的根源。

A2 is a continuation of director Tatsuya Mori's film A (1998), an incredible view inside the compound of Japan's Aum Shinrikyo cult after its leaders carried out the deadly sarin gas attacks on the Tokyo subway in 1995. Most followers had no idea that the attacks were being planned, or even that their new religion had violent aspirations. After the attacks, these followers were left to rebuild the religion where they had once found peace in the face of overwhelming, and understandable, condemnation from the rest of Japan. Central focus is placed on Hiroshi Araki, a young man who finds himself elevated to chief spokesman for Aum after its leaders are arrested. Araki faces extreme hostility from the Japanese public, who find it hard to believe that most followers of the cult had no idea of the attacks and even harder to understand why these followers remain devoted to the religion, if not the violence.
