In one scene, Daniel Bernhardt opens his coat at a club to a security guard to reveal he is armed. Keanu Reeves did the same thing later on in the Matrix. Daniel Bernhardt also worked on the Matrix franchise.
The man playing the tattoo artist is "Slik Rik" Milligan, who at the time was working at Studio City Tattoo in California. He was originally hired only to paint on the yakuza tattoos for the movie, but when a scene called for a tattoo artist he stepped in front of the camera. "Slik Rik" now resides in Hawaii and owns and runs North Shore Tattoo in Oahu.
