Based on a popular swordplay novel, this colorful and complex saga (whose Chinese title literally translates into the poetic Meteor, Butterfly, Sword) has enough conspiracies, stratagems, and sword fights to fascinate even novice kung-fu cinema viewers. The cast of Shaw Brothers' leading swordsmen and swordswomen are masterfully staged by Yuen Cheung-yan, the brother of Matrix and Crouching Tiger Hidden Dragon martial arts choreographer Yuen Woo-ping. The result is both a great action movie and an exceptional dramatic film.
Unfortunately the movie Killer Clans is not yet available on HBO Max.
