This is a very poor film but a very interesting story. Montgomery Clift looks worn and torn in this intelligent thriller that was to be his last film at only 45. Hardy Kruger makes an equally interesting character but more convincing for his vitality. They both find themselves pawns in a political game, both are involuntarily recruited, and they both have some difficulty winding their way out of it. Towards the end of the film it gets finally exciting like a real thriller, but you have to wait long for it. Fortunately a beautiful young lady also gets involved, and she is let alone by the bullies.

The main asset of the film is actually the delightful music by Serge Gainsbourg, which every time it tunes in gives some relief to a rather bleak and sordid story. It is in character very much like "Funeral in Berlin" of almost the same year but more sophisticated and interesting, while the Harry Palmer case is much more attractive as a film. Much of the flaws of the film are due to very poor direction - the directior has difficulties in bringing his actors to life. You must not be that formal and stiff, callous and expressionless in a film that involves great nervous strain, a love affair, brainwash ordeals and an escape for your life. Although the story is good and of great interest, the director fails to bring it sufficiently alive on screen to make it engaging.
