Duel for gold (1971)

Soon-to-be legendary director Chu Yuan had just joined the Shaw Brothers when he helmed this thriller of bickering bandits. Audiences loved watching three pairs of cunning male and female crooks trying to steal a million gold taels from the Fu Lai Treasury House...not knowing that one of them is actually an undercover hero. Even without him, there's no honor amongst thieves, so the double-crosses and deadly duels come fast and furious, all choreographed by Hsu Erh-niu.
