My Best Friend (2007)

Francois (Daniel Auteuil), a Parisian antique dealer, has little time or desire for personal relationships. When his business partner (Julie Gayet) challenges him to prove that he has a friend, the buddy-less Francois tries to find one. When his pathetic attempts fail, he hires a cab driver (Dany Boon) to teach him how to make and keep a real pal.
