 Loosely based on the Jackie Chan movie  _Kwai tsan tseh (1984)_ (qv). The main characters are named after  Jackie Chans and Lola Forners characters Thomas and Sylvia. When  the film was released in Japan it was entitled "Spartan X", and the  video game was named the same. However, when the game was released  in America, the name was changed to "Kung Fu Master" for its arcade  release, and then shortened to "Kung Fu" for Nintendos home console  release.
