Daniel Auteuil is antiques dealer François, a success at business but stilted in matters of the heart. At his birthday party, it becomes apparent he has no clue about the lives of his friends and associates. An expensive bet spurs him on to search for a best friend. Taxi driver Bruno (Dany Boon)--a warm-hearted game show savant--comes along just at the right time.

This is a charming, well-acted and nuanced film. It's not too slow nor too choppy. The characters are interesting and odd, but not stereotypes. The theme of friendship, knowing others, caring is poignant. And the light-hearted touch keeps it from becoming sappy.

I especially enjoyed how little signposts (the vase, the daughter, Bruno's parents, game shows, etc.) impose meaning, further the story and then reflect the theme again later in the movie. (Feels satisfying.)

Definitely a worthwhile, witty film to watch, and a great study of human character. This is one of those great foreign films that often get remade as a cheesy, generic, forgettable American film.
