Summary: Occupied France the subject of a deft, breezy comedy? Believe it. "Bon Voyage" gathers a collection of romantics, fools, and survivors, and puts them together in Bordeaux in 1940. Loosely arranged around the ditzy figure of a famous grand-dame actress (Isabelle Adjani), these hapless creatures trip over each other very amusingly during the course of a couple of frantic days. The central character is actually a young writer (the winning Gregori Derangere), who's torn between panting after the actress or aiding the pretty daughter (Virginie Ledoyen, "8 Women") of an important scientist trying to escape to England. It would be hard to say that any of this amounts to anything substantial, but director Jean-Paul Rappeneau whips it together very attractively, and the Bordeaux location offers luscious views of a pre-war city. Rappeneau's delightful 1966 comedy "La Vie de Chateau", set in Normandy just before D-Day, treads some of the same turf. "--Robert Horton"
