Kommissar X - Drei goldene Schlangen (1969)

From what I've seen of the Kommissar X series, this one definitely takes the cake. The plot involves a kidnapping ring run by a wealthy Oriental "madam." American tourist women are kidnapped, drugged, and sent to a secret island, where they are kept strung out on morphine, while serving as prostitutes to rich tourists. Brad Harris and Tony Kendall team up to nip the operation in the bud, but constantly run into a barrage of thugs, gunmen, and Asian assassins. In my book, this is another reason why director Roberto Mauri is one of the more enticing directors of Italian cult cinema. He doesn't just appeal to the spooks, but to genuine film aficionados as well. His resume extends to many forgotten and obscure corners of the cinema. All in all, he is a wonderful director. This film is really great from a technical point-of-view, and features some very nice improvising by Harris and Kendall. Walter Brandi also appears in a fine role. Thumbs up for the Three Golden Serpents!
