Tony Gatlif, whose Gadjo dilo completed his lyrical “Gypsy Trilogy” in 1997, has made a career of finding formally inventive ways to use music as a principal narrative element in his films. But in Exiles the ways in which it propels the narrative are not nearly as profound as in his previous films. An Algerian-born couple who barely know each other impulsively decide to leave France for their native land, employing assorted modes of transportation to get there. Most of the film concerns their travels through Spain, giving Gatlif a fine excuse to show some mesmerizing flamenco dancing and guitar playing. With Romain Duris, who also starred in Gadjo dilo. In Arabic, French, and Romany with subtitles. 105 min.
