This is not really an early Chabrol who had already been making films for over fifteen years but it does come just before he fully got into his stride and his golden period began with Le Boucher. Fascinating here to see Anthony Perkins with Maurice Ronet and the lovely Stephane Audran, not sure if he knew English or was dubbed but he looks fine. Trouble here is that Chabrol takes forever setting this up and we have to spend what seems an interminable amount of time as the rich are seen to party pathetically with their business transactions forever hovering. Once things do get going there are some great scenes and we struggle to make out who is doing what and for why. Could have done with some of that cinematic style early on but certainly worth a watch for the second half. Apparently referenced in Kill Bill 1 and 2 and I'm guessing that it is the final overhead scene shot in retreating fashion that could Tarantino's eye.
