Wai Ka-fai rewrote most of the script of
The Longest Nite with
Johnnie To. To and Wai had the film take place in Macau based on the chaos the area was experiencing at the time of filming. To took over directing the film after Patrick Yau had shot five scenes with Wai Ka-fai rewriting the script as they were shooting. Large portions of the film were shot in
Macau. The Hong Kong title of the film translates to
Dark Flowers, a slang for an underworld contract. ==Release==
