"Hot Diamonds In Cold Blood" is one of the weakest Eurospy movies out there, and this is coming from someone who enjoys this particular genre considerably more than the average person. What makes it even more disappointing is that it has an experienced genre cast; 3 exceptionally beautiful women (Diana Lorys, Alida Chelli, Rosalba Neri) are largely wasted in brief and underdeveloped (figuratively speaking of course, wink wink) parts, while both the hero and the villains are pretty bland. And there are also a few too many underwater sequences - the kiss of death for almost any action movie, since they are usually so murky and slow. The music score is about the only thing that drives this film forward. *1/2 out of 4.
