If you loved Heart of Dragon, try My Lucky Stars
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Sammo Hung Kam-Bo, and they sit in Action / Comedy territory. If that's the register that drew you to Heart of Dragon, the second film will land in a comparable space — through a different lens.
What My Lucky Stars is
Two Hong Kong cops hop a plane to Tokyo chasing a jewel-fenced ex-cop. Left alone after his partner gets kidnapped by ninjas the straight-laced cop reluctantly reunites his orphanage gang, the Five Lucky Stars, for a rescue. They make it back in one piece give or take a few windows.
