This is basically a "funny" version of Agatha Christie's "Mousetrap". It follows pretty much the same plot, but with a different ending and the play has a mixed cast, this is only women. In sum, it is witty, filled with typical French private jokes, which are understandable and feel international, although if you are French or are used to French movies, you'll probably enjoy and understand it better. I think that the acting wasn't appropriate for this movie, though. This directing would have worked brilliantly as a play, as it stands, it doesn't really deliver and the musical numbers are largely unnecessary. I'm giving it 6 stars because some actors do save the movie and make it an enjoyable piece, were it not for them, this movie would have completely failed.
