Flash Point (traditional Chinese: 導火綫; simplified Chinese: 导火线) is a 2007 Hong Kong action film directed by Wilson Yip, produced by and starring Donnie Yen. The film co-stars Louis Koo, Collin Chou, Lui Leung-wai, Fan Bingbing and Xing Yu. Yen plays Ma Jun, a police sergeant who plants his partner Wilson (Louis Koo) as a mole in a pursuit against a triad led by three Vietnamese brothers (played by Chou, Lui and Xing). Flash Point was repeatedly hailed as a prequel to the 2005 film SPL: Sha Po Lang, which was Yip and 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. In choreographing Flash Point's major fight scenes, 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 August 2007. It was a box office hit during its two-month theatrical run in China, despite receiving mixed reviews. It had also premiered at the "Midnight Madness" program of the 2007 Toronto International Film Festival. Flash Point was later given a limited theatrical release in North America on 14 March 2008, before being released on DVD by The Weinstein Company as part of Dragon Dynasty's collection of films.
