Originally Vielle qui Marchait dans la Mer, this elegiac French comedy is also known as The Old Lady Who Wades in the Sea. Based on a novel by San-Antonio (Frederic Dard), the film stars Jeanne Moreau as an ageing beauty, living with her travelling companion (and ex-lover) Michel Serrault in Guadeloupe. Though forced to hobble about with a cane, Moreau's infirmities do not slow her down in her chosen profession: con artist. She and Serrault have been responsible for some of the most ingenious swindles and extortion schemes in recent memory. While taking her morning walk on the seashore, Moreau is robbed by handsome young Luc Thullier. Not in the least outraged, she senses great potential in the boy, and begins training him for major robbery-while Serrault seethes in comic jealousy. The W.C. Fields-like terms of endearment bandied about between Moreau and Serrault will either charm or annoy you; we liked it.
