Anecdotes

All the money from the film was given to Cheh Chang so he could retire. Rather than using it as retirement funds, Chang used the money to direct another film.

John Woo directed about 60% of the film.

The film was made to aid director Cheh Chang who was broke. When actors Danny Lee and David Chiang found out about Chang's financial situation, they developed the story that was made to be similar to Ying hung boon sik (1986).

The film began production as a benefit for the Hong Kong Director's Union.
