The Polish Weronika, a classical singer with a heart condition, collapses during a performance, after which Kieslowski turns his gaze to the French Véronique, a music teacher who shares the same ailment (much like Kieslowski, who died after cardiac surgery in 1996). Véronique's life follows a similar track, while her affection for Alexandre (Philippe Volter), a puppeteer, suggests the working relationship between the actress and the filmmaker. It's Alexandre, after all, who draws Véronique's attention to the existence of her double (through a photograph she took on a trip to Krakow). In that sense, Kieslowski plays with art as much as identity. Instead of explaining the connection between the characters, he lets the mystery serve as its own reward.

In her commentary, Annette Insdorf (Double Lives, Second Chances: The Cinema of Krzysztof Kieslowski) outlines the reasons she finds the film so metaphysically rich, from the insights into Kieslowski's background to Sawomir Idziak's inventive cinematography. Other extras include interviews with Jacob, Idziak, and composer Zbigniew Preisner; a featurette; a profile of the director; the alternate ending (which feels extraneous); three shorts (the best is 1980's "Railway Station," in which Kieslowski presents a throng of commuters from the perspective of a security camera operator); and an additional short ("The Musicians") about a band of factory workers by his instructor Kazimierz Karabasz. Kieslowski admired this heartfelt portrait for the way it expressed "the human need to create." --Kathleen C. Fennessy
