This movie is more like a theater-play: very much talking and hardly any action. All talking is done in French, and deals with a very haunting issue: in 1959 a former French resistance group reunites to search themselves for a traitor who killed one of them back in 1944. In this way a real Agatha Christie-like plot develops, all set in the long dark shadows of World War II and its horrors. Leading female star Danielle Darrieux gives a glittering performance, both in her talking and in her presence. The male cast around her consists of some of the greatest French actors at the time. 'Marie-Octobre' is not an easy movie to watch: you have to concentrate on it. If you do so, you'll be swept along onto its climax and surprising end.
