The film is an adaptation of the fourth novel in a pentalogy, or five-novel cycle, known in China as the Crane/Iron Pentalogy and written by noted wuxia (kung-fu) novelist
Du Lu Wang. The novels are "Crane Frightens Kunlun", "Precious Sword, Golden Hairpin", "Sword's Force, Pearl's Shine", "Crouching Tiger, Hidden Dragon", and "Iron Knight, Silver Vase". Much of the story is not about Li Mu Bai and Yu Shu Lien; they are in fact secondary characters who only become important later in the series. When a comic-book adaptation of the fourth book in the pentalogy was slated, illustrator Andy Seto re-watched the film to get inspiration for how to depict the fight scenes.
