Here's a real anomaly: a charming men-in-prison movie. Based on an autobiographical manga by Kazuichi Hanawa and accompanied by a serenely hilarious voiceover by star Tsutomu Yamazaki (Tampopo), Yoichi Sai's delightful film depicts daily prison life as a near-Zen experience-endless cleaning, woodshop projects, and military regimentation-punctuated by meals real, imagined, and remembered. If God is in the details, then these mild prisoners are holy fools. Like most great prison films, Doing Time is about a lot more than life behind bars. It's more about the simple, deep satisfaction of a job well done.
