 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.
