Bakeneko: A Vengeful Spirit / Kaibyô nori no numa (1968)

Nabeshima Naoshige murders his lord, Takafusa Ryuzoji, seeking to gain power and steal his Lord's wife. To avoid her fate, Lady Takafusa drowns herself along with her cat in a nearby marsh. A decade later, Naoshige's efforts to steal another woman triggers a curse on him when she also commits suicide at the same marsh forcing him to suffer the consequences of his past actions. This a an awesome black and white samurai/ghost story with terrific fighting, and believable special effects. One of the better films in this genre, thoroughly entertaining!
