In the moving first film of Krzysztof Kieślowski’s “Three Colors” trilogy — each part tells a stand-alone story — Juliette Binoche gives a tour-de-force performance as Julie, a woman reeling from the tragic death of her husband and young daughter. But “Blue” is more than just a blistering study of grief; it’s also a tale of liberation, as Julie attempts to free herself from the past while confronting truths about the life of her late husband, a composer. Shot in sapphire tones by Sławomir Idziak, and set to an extraordinary operatic score by Zbigniew Preisner, “Blue” is an overwhelming sensory experience.
