An extended version, in 2 parts (40 minutes longer), has been made but never shown in the theaters. It was only shown on TV. I think it improves the film, getting us to know the main characters better, especially Thierry, with all the scenes in his High School, not included in the main version. It gives more sense to the whole script, which then holds better than the shorter one. I have sent the update for this extended version to IMDb, and it has been recorded under the reference 050423-085733-754000. It includes the name of the actors playing the parts of Thierry's teachers, who are not acknowledged in the cast of the main version. I don't know is this extended version exists on DVD, but, if it does, I would recommend people to get it and watch it.
