Riki-Oh: The Story of Ricky (原題: 力王, Riki-Oh) is a wild, hyper-violent cult film that occupies a strange, unforgettable corner of action cinema. Released in 1991 and adapted from a Japanese manga by Masahiko Takajo and Tetsuya Saruwatari, the movie is a Hong Kong–produced, Cantonese-language spectacle directed by Lam Ngai Kai and starring Siu Chung “Sioux” Lam (credited as Louis Fan in some sources) as the near-invincible protagonist. It’s the kind of film that makes viewers gasp, laugh, flinch, and keep watching—part exploitation shocker, part B-movie masterpiece, part midnight-movie communal ritual.

Tone-wise, Riki-Oh refuses subtlety. It mixes righteous melodrama with gag horror and cartoonish villainy. One moment is thoughtful and stoic; the next, it’s a head-splitting, bone-snapping tableau meant to elicit both disgust and exhilaration. That tonal schizophrenia is precisely the reason viewers either love it or can’t finish it—yet many come back for repeat viewings.
