If ever a film deserved deluxe DVD treatment, it’s Polish director Krzysztof Kieslowski’s 10-part masterpiece. Each of the hour-long installments — initially made for Polish TV in the late ’80s — takes on one of the Ten Commandments by placing ordinary people living in a Warsaw apartment complex in profoundly complex situations. A girl finds out her dad is not her biological father; a doctor must decide to save one of two lives. Ironic stories of moral quandaries and metaphysical dilemmas are quietly brought to life by extraordinary actors, and the subtle power seen in Kieslowski’s later works (Three Colors: Blue, White, Red) is harnessed and unleashed here first. EXTRAS Roger Ebert’s featurette is a useful primer, but it’s the director’s extended interview and essay that shed the most light on the films.
