This film has a very good cast of first rate actors.However they do rather struggle because the plotting is predictable.The spy is revealed fairly early with a consequent lack of tension.It was totally predictable that he would try to escape in a plane and the end result forecast without aid of a barometer.So that by the end the actors are just going through their races.
