Great cast, neat spy thriller

David Hemmings, Ian Richardson (if he was filmed watching paint dry it
would be worth seeing. Plus cameos from Sam Wanaker and Ralph
Richardson. The players lift this Cold War yarn a good few notches
above the spy-as-superhero movies we see too often. You know there's a
twist coming, and I've seen enough to get most of them, but this one
managed to stay intriguing to the end. Well worth hunting down.
