Have Sword, Will Travel (1969)
"Ti Lung is the armor of an 'armored carriage' taking silver to the capital. Along the way a mysterious knight stalks him, David Chiang. Though he appears to be the robber, he turns out to be his savior" -- Celestial Pictures
Chang Cheh in a more typically wu-xia mode appeals to me far more than his later films, and I liked this a lot. Echoes of Crouching Tiger, Hidden Dragon.
