The late Bruce Baron once renamed this "Nina Farce"... well, I saw Ninja movies that were worse than this. Baron stars in this weird extravaganza as an undercover cop recruited in a secret squad leaded by Bruce Li. Another member is moustached stuntman Tong Kam Tong. They must rescue a princess kidnapped by colorful Ninjas hired by a Russian Barry White lookalike. Basically no-screenplay, just tons of fancy and funny action with a captivating music score by local composer Babida. Beald-head Tong Tin Hey plays an henchmen. Director Michael King was brother of famous director Johnny Mak (Long arm of the law). Jacky Chen Shao Lung (The growling tiger) is the Kung-Fu director. Bruce Li made one more movie (Pink trap) and then retired. Released in HK 12/16/82 it grossed a passable 1,385,425,000 HK dollars. I saw this in a theatre 1982 and still have affection for this joke of a movie.
