Andy On was born on May 11, 1977, in Providence, Rhode Island. A non-martial artist, Andy had always loved Jackie Chan movies and emulated his moves from flips and kicks at his home. In early 2000, while working as a bartender in Rhode Island, someone suggested he should become an actor. Andy, who didn't like the bartending job anyway, decided to go with his gut and head for Hong Kong to begin his career. He was approached by Chinastar founder Charles Heung and world renowned filmmaker Hark Tsui to take over the role of one of Jet Li's famous movie character, Black Mask, in Black Mask 2: City of Masks (2002). Andy went to the Shaolin Temple to train for a month in stretching and martial arts for the role. Despite the poor reviews and bad box office, Andy has continued to act and, in fact, improve in not only martial arts but acting as well. He was nominated for Best New Actor for his role in Siu nin a Fu (2003) (aka Star Runner) and shared the screen with the man who influenced him, Jackie Chan, in San ging chaat goo si (2004) (aka New Police Story).
