Once Upon a Time in China
What they share
Both films are directed by Tsui Hark, and they sit in Action / Drama territory. If that's the register that drew you to Detective Dee and the Mystery of the Phantom Flame, the second film will land in a comparable space — through a different lens.
What Once Upon a Time in China is
You're Wong Fei-Hung in Canton. Western powers encroach. Aunt Yee comes home changed, and then loyalties fracture along new fault lines. Tsui Hark's direction is a furious riposte. The film ponders cultural collision.
