This project was originally conceived as the movie version
of popular Japanese manga SlamDunk! and that's not something new to
Jay Chou, who made his movie debut playing a character from another
wildly popular manga Initial D. Along the way, it was decided to
incorporate some kung fu into the movie, so hence the title, even
if the idea wasn't very original, with Stephen Chow's Shaolin
Soccer coming to mind with martial arts and ball games
combined.

But then the only similarity of this show and SlamDunk
is that both involve basketball.
