Après la vie is a part of a very interesting cinematographic experiment. The other parts are two other films made by Lucas Belvaux: Un couple épatant and Cavale. The three films are set in the same city (Grenoble in the French Alps) during the same period of time and share the same roles. The point is, in each of the three movies the focus is on different people. The leading actors in one movie are the supporting actors in another one, and vice versa. Some scenes in the movies are exactly the same, some are the same but filmed from a different viewpoint, and most scenes are unique to one of the three movies. Belvaux has chosen three different genres: a comedy (Un couple épatant), a drama (Après la vie) and a thriller (Cavale).
So far, so good. The experiment works: after seeing all three of the films, a fourth imaginary film emerges in which all the different pieces of the puzzle come together. There is only one little problem: not all three films are good. The comedy is not very funny, the thriller is not very thrilling, and only the drama is in a way dramatic. I found Après la vie (about a cop who has to become corrupt because he needs dope for his drug-addicted wife) by far the best one out of the three. But perhaps this is because I saw this movie after the other two and knew the story already more or less. Cavale was the first one I saw and, to be honest, I had trouble understanding everything that happened (although a friend I saw the movie with had no trouble at all). But perhaps this is an inevitable consequence of the experiment. So if you want to enjoy an unusual experiment, go see all three movies. If you think that takes too much time and costs too much money, go see Après la vie - a decent drama - and forget about the other two. Unless you want to admire the breathtaking beauty of Ornella Muti: then Un couple épatant is your best choice because she has a leading role in this movie.
