Finding great classic kung fu movies to watch on free streaming services can be tougher than it should be, with myriad options, alternate titles, and questionable quality. For example, one of my favorites is The 8 Diagram Pole Fighter, but you may be baffled when it starts playing, and the title Invincible Pole Fighter pops up instead. They are the same movie, just with a different title, which is commonplace in classic martial arts.
