as no one knows what really happened with the Beast(I know that for sure as it happened in my region), this could be an explaination. V.Cassel is SO GOOD in this movie, completely different from his other roles but he's really frightening. I really like it.
hmmm...the idea may be original, but there is an explaination neither of the beginning nor of the end. You don't know why, where, who and how it ends. Meanwhile, the mathematical theory is wrong(because they don't possibly know where the origin is!!) and some of the results are ununderstandable. Skip on it.
although you will automatically recognize it as a Woody Allen movie, it's far from being a great one. S.Johansson is bloody impressive, and so is W.Allen, but the story is too basic and you can easily foresee the end.
