Green Snake is a 1993 Hong Kong fantasy drama film written, directed and produced by Tsui Hark. The film is based on the novel of the same title by Lilian Lee, itself based on the Chinese folk tale Legend of the White Snake, which depicts the love story between the female snake spirit Bai Suzhen, named White Snake in the film, and the male Human Xu Xian, named Hsui Xien in the film. Green Snake depicts the romance between the two, but features both White Snake and her sister Green Snake, originally a supporting character in the folk tale, as the two main characters.
