This is a very simple - in some ways - and sad movie. A long-divorced couple learn of the suicide of their son, with whom they have been out of contact for years. He sends them each a letter, asking them to spend a week together at different sites in Death Valley (yes, in the U.S.), with the promise that he will appear to one of them.
They meet. They encounter a few dull Americans. They spend a lot of time out in the desert. Lots of old dirty laundry gets aired. The end makes no sense.
When I was walking out of the theater in the small Breton town where I saw this movie - fewer that 10 people had showed up to see it -the usher told me that it was based on the story of the death of Gérard Depardieu's son, Guillaume, and that Guillaume had been his son by Isabelle Hupert. Not true. Guillaume was Depardieu's son by his first wife, Elisabeth, and he did not commit suicide. Nor, as far as I know, was he gay. So much for instant legend.
What was good, indeed very good about this movie was the acting by the two principals. They are both first-rate actors, and they do wonders with what is often not first-rate dialogue.
For what it's worth, it's also interesting to see them as they are now, with NO makeup or attempt to hide what time has done to two formerly very handsome/beautiful individuals. Depardieu has become downright enormous, and not in a good way. He looks downright pitiful in shorts.
There is also some beautiful landscape shots of Death Valley.
Not a movie I would see twice, at least in the theater. But not a movie to overlook, either.
