This mix between Kung Fu and James Bond is very funny in a childish, unpretentious way. Actor Sal Borgese (the mute thief in the story) told me he did many more action scenes with the martial Arts director Cheng Yuanlong (later the legendary Jackie Chan), but they cut alot of material at the montage. If you are fans of old HK cinema you can have a good fun in recognizing many faces: Lo Lieh and Tung Lam were respectively the hero and a badguy in Invincible Boxer aka King Boxer aka Five fingers of death; Actress Shi Szu was an Opera performer promoted as the new Cheng Pei Pei (Pei Pei was the foremost martial actress in the 60's); Shi Szu didn't succeed so much but was a solid performer. Blink and you miss Yuen Biao as an henchmen. The tournament scene where Borgese and Cantafora brag in front of the public that Borgese can defeat Kung-Fu champion Lo Lieh, and then suddenly the two grab Robert Malcolm and throw him on the ring, with the result that the poor Malcolm is badly beaten instead of Borgese, is a riot!
