My Best Friend (2006)

François is a middle-aged antique dealer. He has a stylish apartment and a fabulous life, but at a dinner with a group he considers his dearest acquaintances, he is blindsided by the revelation that none of them actually likes him. He's arrogant, self-centered and harsh, and they don't believe he knows the meaning of friendship. His business partner Catherine makes him a bet: if he can produce his best friend, she will let him keep the massive Greek vase he acquired that afternoon on the company tab. If not, it's hers. Having accepted the wager, François naively tears through his address book, trying to shoehorn an increasingly unlikely series of contacts into the all-important role. Moving through Paris, he keeps encountering a trivia-spouting, big-hearted cabbie named Bruno. Bruno's chatty, lowbrow ways grate against François's designer temperament, but he covets the other man's easy way with people. He convinces Bruno to teach him how to make friends and sets about learning the "three S's" - being sociable, smiling and sincere - though they don't come easy. Ultimately, François victory will depend on Bruno's naiveté in playing along, but what's the cost of cheating at friendship?
