A businessman tries to belatedly learn the fine art of friendship in this comedy from French filmmaker Patrice Leconte. François (Daniel Auteuil) is an antique dealer who runs an upscale shop with his business partner, Catherine (Julie Gayet). François is a gently ruthless trader who will do nearly anything to make a deal, and when Catherine throws him a birthday party, someone points out that all the guests are business associates, not personal friends. While François protests that he does indeed have friends, Catherine calls him on it and makes him a deal -- if he can produce his best friend within ten days, he'll be allowed to keep a valuable vase he recently found for the shop, but if not, the vase will belong to her. François agrees to the challenge, but while going through his address book, he begins to realize he really doesn't have any especially close friends. Over the course of several days, François keeps running into Bruno (Dany Boon), a gregarious and friendly taxi driver, and while Bruno's personality rubs François the wrong way, he notices that the cabbie has a way of making (most) people like him. Eager to win his bet with Catherine, François recruits Bruno to give him a crash course in making friends and influencing people, hoping to find a buddy before his deadline. Mon Meilleur Ami (aka My Best Friend) received its North American premiere at the 2006 Toronto Film Festival.
