The Ghost of Yotsuya (aka Yotsuya Kaidan)

A classic Japanese horror movie. The conniving mother of a Samurai warrior convinces her son to do away with his wife. He poisons her and kills her supposed lover. But the two come back from the grave and haunt him, seeking revenge. The scene where the dead rise from the swamp is amazing. And when the ghosts materialize, no samurai sword can fend them off. Chilling is an understatement. The climactic graveyard sequence is unforgettable. Wow. Creepy B&W cinematography. In Japanese with English subs. 35mm.
