Johnny To is considered one of the best action filmmakers in Hong Kong, and in this smart, stylized gangland thriller (2005) he looks at the messy inner workings of a triad as it prepares to elect a new “chairman” to a two-year term. (The movie gained some notoriety for allegedly revealing arcane details of triad rituals.) Expertly ratcheting up the tension, To depicts the members’ internal debates and negotiations with the police as friction between rival factions boils over into violence. With Simon Yam and Tony Leung. In Cantonese with subtitles.
