A longer trailer (French only) is available here. Click here for the film's website. There is no US release date yet. From the Guardian, a bit of reflection on the import of the film here.
If you don't want to wait (or if like me, you'll pass on Sarah's Key), I recommend the far more subtle and challenging, Mr. Klein,
Mr. Klein is undoubtedly one of the masterpieces of the postwar French cinema; Losey's vaunted visual style is here fused with a brilliantly original scenario by Franco Solinas which captures in chilling detail the complicity of the French citizenry in the anti-Semitism of the Nazi occupiers. Of the few films which even tangentially touch on this topic, ... none has so clearly and effectively articulated the casual acceptance of anti-Semitism in Western Europe. Losey's achievement is magnified by the sophistication of the narrative exposition, which places the theme within the framework of an unconventional psychological detective thriller.
