About Cure

Cure is a 1997 Japanese psychological horror film written and directed by Kiyoshi Kurosawa. Starring Koji Yakusho and Masato Hagiwara, it follows a detective investigating a series of murders whose perpetrators all confess under strange circumstances, seemingly being driven to kill by an unknown force. As the story develops, the police realise all the murderers are in contact with a mysterious young man, who appears to have extreme memory loss. The film received positive reviews from critics and has been described in later commentary as influential on the late-1990s wave of Japanese horror cinema.
