This film was released on Criterion Collection, and it's beautiful. It looks like it was shot and processed yesterday, it was that crisp. And the film's amazing, too.
Did he train you? Did he rehearse you? Did he tell you exactly what to do, what to say?!

This is probably one of the most beautiful restorations Ive ever seen. It almost seemed like a modern film shot it black and white, it was that clear. And the images were amazing.

she's got money, and America doesn't prosecute the rich
They'll hang you as sure as 10 dimes will buy a dollar

Yes, it would be a good movie even if all it had was the gorgeous B&W cinematography and score, but the story itself is spare but compelling. Cherchez la femme!
With regard to Mme Carala's (Jeanne Moreau character) guilt in court, I think the question is one of proof. Even though the French code of justice is not derived from English common law, it nevertheless includes a presumption of innocence, just as in Anglo-Saxon countries. The pictures prove she was having an affair with Julien, not that she planned or participated in her husband's murder. Even her suspicious behavior afterwards (wandering the streets asking for him, tracking down the real killers of the Germans) can be explained away by her trying to protect her lover. Perhaps we're meant to think that Julien ratted her out, but even then some independent proof would be needed, n'est-ce pas?

Romeo & Juliet were quick to kill themselves. I think they did have something to be worried about

why? she's definitely an accessory if not the power behind the scenes. they always give the person who planned the murder more time than the person who actually carried it out. the way they see it, she was the powerful woman playing some fool in her husband's office. anyways, the real question is, how quickly do those kids decide to kill themselves? it's ridiculous! anyways, still a fantastic movie overall.

Neil is right about the quality of the restoration and the score, and I really liked the movie (which I saw many years before). But: would you like to imagine what an American DA would say when the cops tell him he should prosecute the Moreau character for killing her husband? Or for being an accessory? Of course there would be a lot of laughter and then maybe some rueful cursing, but no prosecution, surely.
