Very decent hollywood film minus the usual expected trappings. No happy ending nor overly predictable. More serious drama than I expected after seeing the trailer. The only drawback was Pitts' accent. He was expected to have an accent but in the movie, it was supposed to be sufficiently accurate to fool a native French speaker. Cotillard's character jokes that he sounds more Quebecois.. but even single words betrays his American accent.
Good film overall.
