Upon learning that her promiscuous folksinger mother has died, an 18-year-old dropout (Scarlett Johansson) leaves the Florida panhandle for New Orleans and moves into her mother’s house, which has been willed equally to her and a couple of alcoholic deadbeatsa former English professor (John Travolta) and his teaching assistant (Gabriel Macht). This is mainly the girl’s story, though the numerous southern archetypes out of Tennessee Williams and Carson McCullers (who’s explicitly referenced) keep threatening to overwhelm her. Travolta in particular chews the scenery as the pontificating (and sometimes folksinging) Bobby Long, commanding attention despite his shopworn character. First-time director Shainee Gabel adapted a novel by Ronald Everett Capps called Off Magazine Street. With Deborah Kara Unger. R, 119 min. (JR)
