Remo Williams: The Adventure Begins (1985)

"A hero who doesn't exist must save America from an enemy we never knew we had."

Tough Brooklyn street cop Sam Makin is unwillingly recruited as an assassin for a secret United States organization known as CURE, who fake his death and give him a new identity: Remo Williams. With his appearance surgically altered, Williams is trained to be a human killing machine by his aged, derisive and impassive Korean martial arts master Chiun.
