A fey tale of refined souls prospering in the slums of Tokyo, this 1970 film was Akira Kurosawa’s first in color, and he doesn’t let you forget it: the tonalities are so bold, so broadly symbolic, and so spectacularly deployed that they easily overwhelm the tiny sentimentalities of the story. With Yoshitaka Zushi, Tomoko Yamazaki, and Hishashi Akatagawa.
