Glad to see another Alain Resnais fan. I have to agree this short yet unequivocally powerful film resonates clearly the grotesque reality of the Holocaust. Based on this film, I would recommend everyone: Elem Klimov's Come and See, the greatest (anti) war film I've seen (a subjective opinion, but still once you see it, hopefully you'll arrive at the same conclusion), here's a short description: 'A boy is unwillingly thrust into the atrocities of war in WWII Byelorussia, fighting for a hopelessly unequipped resistance movement against the ruthless German forces. Witnessing scenes of abject terror and accidentally surviving horrifying situations he loses his innocence and then his mind.' - Imdb
Anyway, the last film I've watched was Bergman's The Passion of Anna - a great meta-film, his first 'proper' colour film - experimenting with nuances, form and ultimately the narrative (for example, interviews of the actors talking about their characters are carefully intercut into the film). The ending has to be one of my favourites so far.
