The attempt to cast French actor/writer/director Pierre Etaix as an unsung master of physical comedy is not misguided -- he really does have some marvelous gags, choreographed with beautifully paced precision. However, in "Le Grand Amour," his efforts are wasted on a tired, sexist premise. Etaix plays a successful businessman who has been married for 10 years to an average woman who lacks dazzle. And his mother-in-law is much worse. When his new secretary turns out to be a 18-year-old beauty, he falls in love at first sight and immediately considers leaving his wife for her. Does he have any chemistry with the girl? No. Do her own feelings matter? No. She's his for the asking. Apparently. If you can get past the story's oh-so-French chauvinism, there are some delightful laughs and at least two brilliant set pieces: one, a fantasy in which Etaix imagines driving his bed around the countryside with the girl by his side and, two, a bitter sequence in which he uses a room of items cut in half (even a piano) to show his wife what would happen if she left him and demanded half of his assets.
