Originally produced in Hong Kong as "Tiger Storm" until the production ran out of money and shooting stopped. The footage was purchased by Keystone with the idea to complete the movie. However, upon review of the original material it was decided to scrap it all and start over. The only thing to survive from the original production was the action hero 'Daniels, Gary'.
The second movie that George Cheung, Julia Nickson, and Dana Lee were in together. The first being Rambo: First Blood Part 2 (1985).
