this be truly a kung fu classic . this film appear to have influence martial art film for decade . the spanish guitar background music and the compete school and the impossibly high leap onto the edge of rooftop and catch thrown spear and cheat in tournament and the secret training for an exotic karate technique and theme of patience and perseverance and and more be copy by many later film such a the karate kid ( 1984 ) and hero ( 2002 ) and kill bill volume 2 ( 2004 ) and and kung fu hustle ( 2004 ) . i feel lucky to have first see this film in 1972 and shortly after it be release and just before kung fu film become mainstream and before bruce lee become a household name . i saw it with two buddy of mine in a downtown san diego theater frequent by sailor and and although the scene of the glowing red hand and gouge eyeball get some laugh and clearly the audience be get into it and a be our little group . it be a very memorable movie for me . decade later i could still recall several specific scene and even after i have forget the film title . this film be extra special to me now because one of those two buddy with whom i first saw it ( sailor kenneth lee hines of the kitty hawk ) have since pass away and so this film serve a a memento of that day together before we take judo and karate lesson in subsequent year . relative to kung fu film and i would rate this film a positive . but since i have to keep the large film audience in mind and i will more objectively rate it a positive and due to obvious technical flaw . i just recommend that neophyte viewer consider those technical flaw to be proof of it vintage nature and of it authenticity and and then merrily proceed to enjoy it testosterone charge mayhem .
