Dennis Law Sau-yiu (born 1963) is a Hong Kong film producer, screenwriter and director. He is the former chairman and executive director of Milkyway Image, and a founder of its subsidiary company Point of View Movie Production Co. Ltd. Films directed by Law include teen comedies such as The Unusual Youth and Love @ First Note, and martial arts action films that include Fatal Contact and Fatal Move.
Law studied filmmaking at university in Los Angeles. He holds a Bachelor of Arts Degree in Communications from Loyola Marymount University.
On his return to Hong Kong, rather than pursue his career in film, Law decided to go into real estate. He later befriended Charles Heung, who advised him to learn from veteran filmmakers such as Herman Yau. In 2003, Law befriended prolific filmmaker Johnnie To and became his financial partner at Milkyway Image, serving as a chairman and executive director. Law had many opportunities to travel to the world's film markets and festivals, meet film industry personnel from different parts of the globe, find out their views of Hong Kong cinema, as well as seeing To on set as a director. Apart from filmmaking, Law is currently a managing director of the Yu Tai Hing Company Ltd., which is a well-established private property investment and development group in Hong Kong.
