In many ways Akira Kurosawa's Ikiru is a non-religious version of tales like A Christmas Carol or It's a Wonderful Life.
In many ways it is Akira Kurosawa's best film. Interestingly, it was released two years before Seven Samurai in Japan, but only made it to the US about 8 months before the later film did. It's fun to think about the universe where the West had more time to absorb and become obsessed with Ikiru, a universe where Spaghetti Westerns were actually Spaghetti Existential Civil Servant Narratives. Good times?
