The entire movie 5x2 or Cinq Fois Due (maybe?) is in reverse. The couple is getting divorced and then every scene takes you to a step earlier in their lives until the day that they met. I'm not sure how you would know what was going on unless you read the back of the movie case beforehand. But I'm not the brightest bulb on the Christmas tree.

There's a great song in the movie that I can't get out of my head. I kept playing the scene over and over with the song because I got hooked on it. The tune part is good but the words are not in English so it's not like getting "Ring of Fire" stuck in your head. I keep humming that song, too. It's so bizarre.
