When Chow Yuen Fa was younger, he was described by a respected Chinese director as "The greatest actor in the history of Chinese cinema", I think no one thought another actor could surpass him, yet Tony Leung has since surpassed him by thousands of miles. He doesn't try to act when he is in character, if one watches "Infernal Affairs", one gets the feeling that this guy was trying not to act at all in playing this role, his gestures kept at the minimal.
