Black Rain is a superb film, but watch out for the DVDs currently being sold for as much as $300 apiece. I have the DVD, and it's terrible. Very tiny non-anamorphic image that has to be blown up to resolution-killing size. Acceptable sound. This is a primitive DVD that absolutely *has* to be rereleased.
BTW, I also own the laserdisc and the VHS of Black Rain. The VHS is a huge step upward from the DVD! And the laserdisc has far and away the best picture of them all—subtitles in the black, sharp, big picture, simple but very good soundtrack. Buy the VHS and avoid the preposterous prices these scam artists are demanding!
