Overwritten by Billy Crystal and Peter Tolan, overdirected by Joe Roth, overplayed by most of the cast, yet typically undernourished, this would-be satirical comedy, about a movie-star couple who have broken up but must give interviews together to publicize their final movie, seems very vaguely inspired by the screwball comedies of the 30s. Among the usually efficient actors (including John Cusack, Catherine Zeta-Jones, Hank Azaria, Christopher Walken, and Alan Arkin), only Julia Roberts and Crystal himself (who also produced) emerge relatively unscathed. They appear to be acting in a different, more reasonable movie than the others. 100 min. (JR)
