Middle-aged soul meets middle-aged soul--despite their unlovely exteriors--in this Marry-style wisp of a French import. Philippe Lipenchky, 37, 240 lbs. and 6'4"" with the face of a potato, is known in the professional wrestling ring as the satanic ""Mephisto King."" Philippe is seemingly content in his bachelorhood, wrapped up as he is in his culinary skills and paintings of geraniums--both thoughtfully delicate in execution. Likewise Jacqueline Puisset, a 40-year-old book-store owner with a ""disordered face"" and a walleye, is resigned to good works with senior citizens, to being indulgent ""Tata"" to her sister's children. But when indulgent Jacqueline goes with her nephew to a wrestling match, Mephisto King (ritual loser) flies over the ropes, lands on her, breaks her leg. . . and visits her in the hospital. True, Philippe--who can place only one-fourth of his rear on a chair--seems to Jacqueline a ""blushing mountain."" Yet why does she feel abandoned when the ""gorilla returns to his native forest""? The two drift apart--Philippe endures a dreadful vacation in Tunisia, Jacqueline has a jaunt in Paris--but they'll eventually clang together, knowing they're really ""beautiful."" Cauvin has all kinds of fun with the pro-wrestling biz (a dressing-room phone is answered with ""Cro-Magnon here""), though Philippe's contours get more giggles than one really wants. All in all: featherlight, hyperbolic froth.
