Based on real events starred by a true bank robber named Eddie Chapman , this film packs action , suspense , warlike feats and being quite entertaining. First-rate main cast as Christopher Plummer as an amoral but sympathetic double agent adding a bemusing touch , Yul Brynner as a disillusioned German officer, Von Stauffemberg-alike , and a splendid Get Frobe as a cunning Colonel . Ample and stunning supporting cast with a magnificent Trevor Howard , and the beautiful Claudine Auger and Romy Schneider, among others . Here appears uncredited prestigious secondaries , such as Gordon Jackson , Howard Vernon , Bernard Fresson and Gordon Jackson . Colorful and evocative cinematography by Henry Alekan , Terence Young's usual cameraman (Mayerling , Poppies are also flowers) . Enjoyable musical score by George Garvarentz in a James Bond style . The motion picture was professionaly directed by Terence Young , but contains some flaws and gaps , though tension at times, as well . The film was realized in his best period when he made the classic Bonds films (Dr No, From Russia with love and Thunderball). In fact Young directed actors who played in James Bond movies as Claudine Auger-Thunderball and Anthony Dawson-Dr. No and also performed Gert Frobe who made Goldfinger and Terence wanted his Dr. No leading lady Ursula Andress to star opposite Christopher Plummer . Rating : 6/10 : Acceptable and passable.
