"Please play the song. You know, the famous one." Jewish restaurateur Laszlo and his restaurant pianist Andras both love the beautiful waitress Ilona. And she loves both of them, forming a bittersweet triangle mirrored by the passion and longing of Andras song "Gloomy Sunday," a tune that becomes a global hit and has a profound, unexpected sway over listeners. Gloomy Sunday, winner of major German film awards and an art-house favorite that ran 70 weeks in Boston, hits all the right notes with its poignant, glowingly shot tale set in Budapest during the Holocaust and, like Schindler's List and The Pianist, filled with the passion and pain of that tragic era. The song itself - recorded by Billie Holliday and other greats - is the stuff of legend, reportedly having a fateful real-life impact similar to that shown on screen. But it's love's power that is ultimately at the heart of this acclaimed film. And from the opening scene to the deft twist ending, that power is extraordinary.
