"First he caught one snake... Then HUNDREDS more!... Then he trained them all to kill!"
This is a Hong Kong horror movie/softcore porn movie from the 70's. Zhihong is a sick and sadistic young man in Hong Kong who is bullied, robbed, and brokenhearted, and turns to using snakes that follow his commands to kill people. He also uses some monitor lizards to attack a woman who is tied up and helpless in a horrible scene. I told you he was sadistic. This is one of the rare uses of lizards as weapons in a movie. These are probably Common Water Monitors, varanus salvator, which is the species native to Hong Kong.
