This is a brooding adaptation of a good novel by Robert Harris and I would highly recommend it. Anton Lesser is superb in the role of March, switching from the gentle, loving and violent and all points along the scale. The other characters also play their parts well too but I think he is key. It is quite clear that the crew making this went for atmosphere and it shows. The use of real background noises and music managed to create something that sounds naturalisic but was the result of effort. From the opening scenes when the phone call which starts the whole story off chimes in with the music, there is such attention to detail. The final moments are genuinely chilling. It's an interesting take on "what might have been" if Hitler had won WWII and how America would have reacted. If you like a good thriller, I would recommend this.
