Brilliant film. It's about a young couple going to a y2k party, she wants a baby there and then, he's not sure and through a little incident the chance is lost. He then accidentally finds a way into the future and encounters his son (Belmondo) who is starting to lose his leg because he's not made yet. The whole future family tries now with different methods to persuade him to change his mind or they are all lost. I say no more I saw it with english subtitles and missed probably some of the more in-jokes, but even though a thoroughly enjoyable experience. You have a film with a rather serious background ( reasons for having a baby or not, while thinking about the future), great actors ( have a look at the totally stoned brother), loads of enjoyable little sequences ( the beginning is great . I thougth first I was in the wrong movie; and then the next ten minutes relate very nicely to the title, pay attention to details there). The Paris in the sand is very well done with loads of details in the background. All in all if you have some French, go and see it.
