Iron Bones.

Iron Bones, about a young lad that learns a secret Tai Chi type of style called the Wind Palm, where you can kill with chi blows. Sure, it's a little crazy, but the acting is a big cut above most martial arts movies and the sword fights are pretty good. And Sam the Seed shows up, sans wig, as a dirtbag Shaolin monk after the book. Han Ying Chieh, the big boss, is one of the thugs in the background.
