Similar film?
A few years ago I saw a film that I thought was, er, "inspired" by Black Rain. I only remember one scene, but I think the plot was similar - a US cop chases a gangster in Japan. The scene I remember was the hero going to a house of an older oyabun who was the gangster's enemy, to ask for help. The oyabun agreed but a while later the hero returned to the house and saw tons of cops outside: turned out the gangster got to the older oyabun and killed him.
I also think it may have ended with the cop catching the gangster and the gangster escaping, upon which the cop found him again and this time killed him... Anyone recognizing any film in this?
