The whole storyline is different and completely unpredictable. Of course, the ending was done in Hollywood fashion, so that part was telegraphed. Even so, the movie was entertaining and enjoyable. I think if this was an American made movie it may have just been simply corny.
This is a French movie and requires reading English subtitles unless you understand the language. I couldn't find a preview with the subtitles.
