Yes, it's one of those so many Eurospy made in the '60s, which amounts to a decent level, acceptable to a demanding spectator. Horst Buchholz (dead in 2003), one of the seven gunmen in "The Magnificent Seven"(1960), is here the beautiful boy who beats and shoot everyone and stays with the girl in the end. The girl is the beautiful Sylva Koscina(dead in 1994), the woman-killer Penelope in "Deadlier Than the Male", here an American agent. Klaus Kinski(dead in 1991), as a villain, as usual, appears too little. Gérard Tichy(dead in 1992), another villain, appears more than him. Last but not least, Mario Adorf, the best actor in the whole film, as in all the movies he played, a living legend, is another villain. Him and the director, Antonio Isasi, are the only still alive. The plot is cheap, as usual, a kidnapped nuclear expert, a lot of ransom money, a lot of Chinese spies, stupid Turkish policemen, etc. But is well done, not bad!
