I'm not a big fan of French dramas, which always seem very mannered, but I'm a huge fan of French comedies. My Best Friend is a perfect example: funny, interesting, and insightful. A narcissistic antiques dealer goes on a search for a best friend after his business colleagues accuse him of having none. He's driven around from potential candidate to candidate by a trivia-loving cab driver, who gives him lessons in being sympathique and tries to steer him toward the true meaning of friendship.
The star, Daniel Auteuil, is the French Robert DeNiro. Besides looking a bit like DeNiro, he has the same talent for being equally brilliant at drama and comedy.
