WHEN I first saw this film, in London, in 1958, I was bowled over. I had never seen a film like this before. It had a strange, hypnotic effect, quite unlike the films that I had seen previously and it left a lasting impact.I believe that Odile Versios Marina Vlady are sisters, if not twins. Certainly the interaction is amazing in its power to influence the viewer.If this has been converted to DVD - in Region 2 format - and in the original French language, I would love to hear about it where it can be purchased.
