Ringo Lam
Filming began in late 1982 under the direction of Po-Chih Leong, director of the generally well-received "Hong Kong 1941". According to Ringo Lam around one-third of the film had been shot when Leong resigned after arguing with producer Karl Maka. In need of a quick and inexpensive replacement Maka gave the previously unknown Ringo Lam his big break. Later in an interview Lam explained, "I have no choice, I need food, so I do the best I can ..." Lam received sole directing credit for the film.
