The Castle of Fu Manchu

Dr. Fu Manchu (Christopher Lee) wants the Earth's oceans frozen, and he has a new device built to do it. Jesús Franco, shooting this fifth and final entry across Spain, Italy and West Germany, sets Interpol's Nayland Smith (Richard Greene) against him once more, with Dr. Petrie (Howard Marion-Crawford) at his side. Fu Manchu has threatened the world before, and he does it again, patient and sure that he is owed it.
