- Any On, Black Mask 2: City of Masks, Hong-Kong-US, 2002. Koos and Raymond Wong Ho-Yin were in the mix for Black Mask, in an indirect sequel to the Jet Li movie and character (masked vigilante Super Soldier). Finally, director Hark Tsiu decided to take a chance on On, an actor almost totally devoid of any martial arts experience. He was immediately dispatched by the movie’s action director, Yuen Woo-Ping, to a Shaolin Temple to study stretching and Wushu for a month. By 2021, On had completed 46 other movies. Wong Ho-Yin supplied the Cantonese voice for Robert Alen Mukes’ Snake.
