Green Snake

Music & Lyrics by James Wong
Performed by Shu-Hua Chen,...and this one's very good. It's a retelling of the Chinese legend Madam White Snake, and while some of the effects aren't what a big-budget film would allow, Cheung and Wang convey a sexiness in their roles that make it highly entertaining.

Shaw Brothers made a version of the story titled Madam White Snake in the 60's or 70's. In 2001, there was a very lengthy Taiwan-produced TV series of the same name. So far as I know, neither of these are out on DVD.,
