High Quality Content by WIKIPEDIA articles! Flash Point (traditional Chinese; simplified Chinese: pinyin: Dao huo xian; Cantonese Yale: Dou fo sin) is a 2007 Hong Kong martial arts action film that was directed by Wilson Yip, and features fight choreography by the film's producer and star Donnie Yen. 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 gang led by three Vietnamese brothers (Collin Chou, Lui Leung-Wai, 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 sequel 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.
