Mr. Ling is the fictional technicial liaison of Auric Goldfinger and the former quaternary antagonist of the 1964 James Bond film Goldfinger. Portrayed by the late British actor Burt Kwouk, the character would later be re-imagined for Activision's 2012 James Bond video game 007 Legends.
He is witnessed overseeing the operation of the industrial laser that nearly bisects Bond, and later, during the raid on Fort Knox, is seen supervising the priming of the atomic device intended to irradiate the gold reserves therein.
Near the end of the film, Goldfinger, disguised as an American army officer, callously guns down Ling to convince the incoming troops he is on their side.
Ling appears in the Goldfinger level and is first seen talking to Pussy, who wants the report on the gas containers, but he tells her that he only listens to Goldfinger and she tells him that he has thirty minutes. He later appears with Pussy and Goldfinger about Ling ignoring her and Goldfinger tells her that Operation: Grand Slam will go on with or without her help. He later appears in the passenger seat of Bond's Aston Martin DBS V12, holding him at gunpoint with a Walther P99 and tells him to drive back to the complex.
As he drove on, Bond tells him to fasten his seat-belt and quipped "I wouldn't want to lose a passenger." and pressed the passenger ejector seat button on the gear nob, releasing Ling from the car, His fate is unknown.
