Alain Chabat is a very popular French actor. This movie constitutes his first transition behind the camera. Far from being a perfect success, "Didier" remains a fair and honest comedy.
Alain Chabat adopted a correct making that contains interesting clever visuals and ringing brainwaves. It succeeds in compensating a rather slight screenplay. It's based on a convenient situation: this is the story of a man (Jean-Pierre Bacri) who's very embarrassed because he's got to cope with several problems, especially professional. One of his friend asks him to take care of his dog, "Didier". One morning, "Didier" has become a man... Moreover, some parts of the screenplay make it conventional, Didier will find out (unwittingly) the solution to solve his master's worries and predictable (imagine the feelings of people who see a man on the street who behaves like a dog).
At last, the movie loses of its lure when it comes to deal with football (Jean-Pierre Bacri plays the role of an unlucky trainer). Despite everything, some dialogs and several sequences are funny enough to burst into laughter. The result isn't great but it's nice. It's also a movie with an ounce of fantastic. One last thing: Alain Chabat had the good idea by not revealing the truth about Didier's transformation into a man.
