Interesting in that it has a German lead, played by a German actor, who you actually sympathise with. Very much not a jingoistic war film, and not what you would expect. Veidt stands out in this as a an actor, his experience really shines through and he comes across as a more realistic, where some of the British actor comes across as 2D. Nice character study of a professional officer who sticks by his code, despite the circumstances. Atmospheric and well made, solid British war spy flick.
