After watching The Lady Hermit last year I somehow failed to dedicate my life to Cheng Pei-Pei in Shaw Brothers films, but now I've come to my senses.
This has it all: secret identities and secret rooms, Cheng holding off sixteen bandits (with a whip!), and my favorite, her and her uncle leaping to the top of the wall and then down on the other side, rather than walking through the wide-open gateway. The version on Prime is gorgeous, far from a given with these older films. To wuxia!
