Flash Point (aka City Without Mercy) is a 2007 Hong Kong martial arts action crime film directed by Wilson Yip, and also choreography and produced by Donnie Yen and starring Yen, Collin Chou, Louis Koo and Ben Lam. This was Ben Lam's final film appearance, who has retired from acting.
Yen portrays Ma Jun, a police sergeant who plants his friend and partner, Wilson, (Louis Koo) as a mole in a pursuit against a triad led by three Vietnamese brothers (Collin Chou, Ray Lui, and Xing Yu).
Flash Point was repeatedly hailed as a prequel to the 2005 film SPL: Sha Po Lang, which was Wilson Yip and Donnie Yen's first feature-film collaboration as director and star respectively. Yen denied the SPL prequel reports, claiming that Flash Point was a completely original film. Principal photography began in Hong Kong from November 2006 to March 2007. For his conception of Flash Point's major fight sequences, Yen relied on the use of mixed martial arts, working alongside an international group of martial artists. His work as a choreographer won him "Best Action Choreography" awards at the 27th Hong Kong Film Awards and the 2008 Golden Horse Film Awards.
Flash Point was released in Hong Kong on 9
