An epic set against the breathtaking landscapes of ancient China, the film Crouching Tiger, Hidden Dragon is based on the book by Du Lu Wang, which is part of a five-novel cycle known in China as the Crane-Iron Pentalogy. The Weinsteins have also acquired the rights to turn the other novels in the cycle into motion pictures. The plot centers on two warriors searching for a magic sword. Their journey leads them to an amazingly athletic daughter of a nobleman. The film, directed by recent Oscar winner Ang Lee, was known for its complicated martial arts choreography, which was created by Yuen Wo-Ping.
