"Le Diner de Cons" is one of those great comedies that the French know really well how to produce: The action is fast, the scenes are hilarious, and the viewer just can't stop laughing as totally extraordinary things happen in totally ordinary circumstances. The mastery in this type of films is that they need not be big-budget productions ("LDdC" has been actually shot mostly inside a single apartment), while they manage to achieve a very high rating for their impeccable viewing pleasure they bring to us.
"LDdC" is about a group of rather cruel friends, who have fun by organizing dinners in which they invite idiots and get amused by them. The winner is the one who will bring the biggest idiot, and Pierre (Lhermitte) thinks he was found the world champion in the face of Francois Pignon (Villeret). He therefore decides to invite him in his house for a drink, and then take him to the dinner. However, things do not go as planned, as during Pignot's stay in Pierre's house unbelievable things begin to happen...
Villeret is simply amazing in his role as Pignon, standing above everyone else in this film. This should not mean that the other performances are not good, however: In fact, everyone does a good job, despite the fact that most actors perform very short appearances.
"LDdC" is a movie that will make you laugh, but in fact, it will also make you think; behind the fun, the film conveys a very humane and meaningful message. Don't miss it! 9/10.
