Contrarily what another user review said here, this is NOT a Shaw Brothers movie, it was produced by the independent company Cheng Ming, since actor-director Jimmy Wang Yu divorced in a very traumatic way from the Shaws in 1970, so he was forced to relocate in Taiwan where he made his subsequent movies, including this really funny Wuxiapian plenty of action (with an encreasing use of a stunt-double for a little overweight Wang Yu). If you like MARTIAN arts cinema filled with high jumps and almost supernatural Kung-fu, you can't miss this one: not totally weird as Wang Yu's previous extravaganzas The One Armed Boxer or Master of flying guillotine..., and not as good as them, but still enjoyable. You must forget to be an adult and back to see this with a childish eye. Moreover if you, like me, are familiar with those actors, the presence of Kung-Fu cinema vets like Lung Fei (with no moustache, this time), Kam Kong (the blind Lama in Master of the flying guillotine...), Lei Chun (a regular in those matters), Wang Yueng Sheng (Okinawan karateman in One Armed boxer), the moustached bulky Sit Hon, Ma Kei (also in One Armed Boxer as Wang Yu's master) and many others, adds fun. Released 11/12/1977 in Hong Kong, also titled Revenge of the Samurai, and written by famous Martial Arts novelist Gu Long, author of the script in many Shaw Bros' classics like The Magic Blade, The Sentimental Sworsdman, Full Moon Scimitar and others fantasty-adventures directed by legendary Chu Yuen.
