The Big Boss (Chinese: εε±±ε€§ε ; originally titled as Fists of Fury in the United States) is a 1971 Hong Kong martial arts film directed by Lo Wei (who also wrote the film) and Wu Chia-hsiang. Bruce Lee stars in his first major film in a lead role, and his first Hong Kong film since 1960. The film co-stars Maria Yi, James Tien, Tony Liu, and Nora Miao. Originally written for Tien, the leading role was given to Lee instead when the film's original director, Wu Chia-hsiang, was replaced by Lo Wei.
