Heroes of Shaolin

Heroes of Shaolin aka Heroes of the Wild is the Americanized title for the 1977 Hong Kong kung fu epic Daai miu si yue siu piu haak. Filmed in Taiwan, the two-part story was directed by William Chang and co-written by Chang and relatively unknown kung-fu film writer Chang Hsin Yee. Like many kung fu movies from the late 1970s, the main theme of the film focuses on revenge, but the story holds a unique twist that sets it apart from many other films of the era. The film is set in the Yuan Dynasty in the 13th century.
