    • Trivia
      Olivia Hussey's second and last Hong Kong movie.
    • Alternate versions
      German VHS release by Concorde Home Entertainment was cut by two minutes and thirty-seven seconds to tone down the violence. Despite that, it didn't stop the government from banning the movie entirely in Germany. Fortunately however the banishment was lifted in 2007 and the FSK granted the completely uncensored version a "Not under 18" rating.
