Released to zero fanfare and tepid reviews - my most undervalued film so far this year, it's wonderful. Perhaps it is an ordinary spy thriller but that's just a framing device (like the beautifully shot and helmed dinner sequence) for what the film really is, a tragic love story. Chris Pine and Thandiwe Newton are sublime, subsumed with passion and regret, it's beautifully shot, sound-tracked and story-boarded - so the delicate pace drip feeds a continually changing and compelling world. The riveting story here isn't a who done it spy drama but the question that has defined each of the two leads lives, why did you break my heart? The answers are shattering.
