仁義なき戦い
Fukasaku biographer Sadao Yamane believes "Battles Without Honor and Humanity" was popular because of the time of its release; Japan's economic growth was at its peak and at the end of the 1960s the student uprisings took place. The young people had similar feelings to those of the post-war society depicted in the films. Yamane also stated that for the rest of his career Fukasaku was approached many times by producers to create movies similar to "Battles", but always turned them down wanting to move on to films he found interesting.
