"Trained to destroy! Hired to kill! Primed to explode!"

Little Godfather from Hong Kong (1974)

Bruce Liang plays a Chinese Kung Fu movie star, who during his free time carries on a one-man crusade against drug dealers. The villains trick Liang into signing up to appear in a new martial arts movie. The plan is to kill Our Hero while the cameras are running, and make it look like an accident.
