you should find many different editions of imamuras "warm water under the red bridge" with koji yakusho out there... theres a dvd of "black rain" coming in may in HK... there apparently a couple of other films coming soon in the UK, but i cant remember the titles : i think theyre in the "masters of cinema" range...
