Louis Garrel has the ideal face for this strenuously whimsical French musical romance, writer-director Christophe Honorés bittersweet tribute to Jacques Demys song-filled confections à la The Umbrellas of Cherbourg. Actor Garrel (The Dreamers), of the heroic nose and antsy emotionalism, plays unlucky lover Ismaël, a Parisian trying to deal with loss by bursting into song (and dance) on the street. Joining in are Ludivine Sagnier as his main squeeze, Clotilde Hesme as the other woman, and Grégoire Leprince-Ringuet as the other man. Composer Alex Beaupains songs are instantly forgettable but Garrels brilliantly daffy, moody performance is not. Completely impractical and not for everyone. The ideal 3 a.m. movie (100 min.).
