George Cukor directed this all-female 1939 classic, based on the Clare Boothe Luce play about gossip, adultery, and divorce. Great line alert, spoken by Joan Crawford: "There's a name for you, ladies, but it isn't used in high society . . . outside of a kennel." Check out this classic as preparation for, or in lieu of, the forthcoming - and, perhaps, doomed to disappoint - remake starring Meg Ryan, Annette Bening, and Eva Mendes.

Remake of Francis Veber's French comedy about an accident-prone rich girl who disappears in Mexico and the disaster-prone wimp sent after her on the theory that he'll find the same banana peels she did. Danny Glover is occasionally funny as the tough private eye babysitting Martin Short's clumsy searcher. (PG-13; runs through Sept. 18)
