Production:
The film is a tribute to director John Woo’s mentor, Chang Cheh. The stylish appeal also came from Akira Kurosawa influences. The main character Tsing Yi is an inspiration taken from the real-life assassin Jing Ke, who is historically remembered for his failed assassination attempt of Qin Shi Huang. The year the film was released is also the same year John Woo met Tsui Hark.
