The Idiot, based on Dostoevsky’s novel, is a 1951 Japanese film directed by Akira Kurosawa. Kurosawa writes:"I had wanted to make The Idiot long before Rashomon. Since I was little I've liked Russian literature, but I find that I like Dostoevsky the best and had long thought that this book would make a wonderful film. He is still my favorite author, and he is the one — I still think — who writes most honestly about human existence."
“Dostoyevsky wanted to portray a genuinely good man. It may seem ironic choosing a young idiot as his hero. But in this world goodness and idiocy are often equated. This story tells of the destruction of a pure soul by a faithless world.”
