All reference sources cite this as the best of Christopher Lee's Fu Manchu movies. The movie begins with a well-executed (no pun intended) beheading scene, but the rest was very disappointing for me. For one thing, the Fu Manchu character in this movie is not cruel enough, the only instance of cruelty he inflicts on his prisoners is drowning a girl in a tank. Yes, the movie overall has a lavish look to it, but it lacks guts.
