Espionage dramas which depend on bureaucratic characters engaged in prolonged conversations rarely make good movies and this is no exception. It's competent but never sparks any real interest and the plot seems a bit muddled.

There are a number of good names in the cast and they do the best they can with pedestrian material. Top billing goes to George Peppard who plays an Englishman but his American accent is explained by saying that he grew up in the United States. He's involved, in a vaguely romantic way, with two different women -- Joan Collins and Judy Geeson -- but not much comes of this. The ads hint at some hot bedroom action between Peppard and Collins but most of these scenes must have been left on the cutting room floor.

Location work in Greece and Istanbul is, like the rest of the movie, strictly routine.
