The third and best feature (1994, 99 min.) of Krzysztof Kieslowski’s highly ambitious “Three Colors” trilogy concentrates on the theme of fraternity (Blue tackled liberty, White equality). The principal characters are a young student and model (Irene Jacob) and a cynical retired judge (Jean-Louis Trintignant) whose paths cross by chance in Geneva, and in a way their meeting comes to stand for a good many of the other accidental incidents threaded through this densely textured movie, including one that ties up many of the loose ends of the two previous films. The telephone and (to a lesser degree) the TV set both play substantial roles in linking these and other lives, but they are far from the only linchpins in Kieslowski’s poetic universe; among others are the color red and the filmmaker’s own sardonic identification with the mordant former judge, who eavesdrops on the phone conversations of his neighbors and seems to hate them and himself in about equal measure.
