Nobody dared in reviewing this Fantomas, directed by Robert Vernay. I don't know any great title by this director, except Le Comte De Monte Cristo. Fantomas Contre Fantomas is not a masterpiece, but is nervous enough, especially the ending. And for lovers of old France like me, we see a lot of settings in Paris that have completely changed today (Bercy, La Seine, La Bastille, ...) or disappeared (Michelin panels). These old movies are documents when shooting on location. That's why I love watching old french movies even if there are not masterpieces. Fantomas Contre Fantomas is worth a look. I don't know why this Fantomas is so unknown, it is unfair, because the ending is great and scary.
